[CHECKLIST] 10 Safety Tips in the Grow Room

Pipp Horticulture at Candre

Grow Room Safety Is Key

The indoor cannabis cultivation environment is an exciting place, one brimming with life and growth. You’ve no doubt hired a supremely talented team to run the operation, but general reminders about grow room safety are always welcome.  We’ve compiled 10 simple but essential tips for maintaining high safety standards in your grow rooms. These tips are meant to be regularly applied, as safety is an ongoing process. Encourage your team to consistently review and adhere to the safety protocols for your grow room.

1. Check Your PPE on a Monthly Basis

Personal Protective Equipment (PPE) may have garnered the spotlight during the pandemic, but workers familiar with food-grade manufacturing environments or horticulture spaces have long been aware of the importance of these products. PPE protects employees from exposure to hazardous substances, plant allergens, and other physical injuries. 

Monthly checks and immediate replacement of worn or damaged PPE are vital to maintain high safety standards. Doing so will ensure that workers are adequately protected against potential risks from fine plant matter. 

This not only complies with health and safety regulations but also fosters a culture of safety within the workplace. Culture is very important when it comes to safety.

Conduct monthly PPE checks and replace any worn or damaged equipment immediately.

2. Understand Stability with Mobile Racking

Mobile racks are an effective tool when laying out your indoor cultivation environment. Your team can really expand their use of space in the grow room, but they must also be mindful of safety protocols.

Staff training, even on something as routine as moving mobile racks within the grow room, is always important. This is especially true for new hires who may be coming from cultivation businesses that used different styles of vertical racks. Make sure that everyone in the grow room understands how to engage locking mechanisms on all mobile racking units when not in use to prevent unintended movement. Include those seemingly minor practices in SOPs: Lock the units in place after any adjustment. 

Mobile racks can be made available with an Anti-Tip Track, as well, which is required in seismic zones. Consider the reactions to the April 5 earthquake in New Jersey, which rattled workplaces along the coast. 

Implement a checklist for periodic safety checks of your mobile racks’ wheels and tracks.

3. Understand Weight Distribution and Load Capacity

On a similar note, make sure your team knows what your racks can handle. Understanding and adhering to the weight limits of racking units is crucial to prevent collapses or structural failures that could result in injury or damage. 

Actionable steps include clearly labeling each racking unit with its maximum load capacity and training staff on how to distribute weight evenly across shelves. Regular inspections should be conducted to ensure that racks are not overloaded and that heavier items are stored on lower or middle shelves to maintain stability.

Label your racking units with maximum load capacity.

4. Monitor Your Electrical Connections with Thermal Imaging

Given the extensive use of electrical equipment in cannabis cultivation, electrical safety is important to prevent fires, shocks, and equipment failures. Proactive inspections help identify potential hazards early. This protocol helps maintain electrical systems safely and efficiently. 

Lights can overheat if not properly installed, for instance, or if the electrical infrastructure is overloaded. Implementing monthly inspections allows for the early identification of potential hazards, such as frayed wires, loose connections, or overloaded circuits, which are common issues that can lead to serious accidents. 

During these inspections, use a thermal imaging camera to detect hot spots invisible to the naked eye, indicative of electrical overload or failing components. This proactive approach minimizes downtime and protects both the workforce and the investment in cultivation infrastructure.

Beyond your inspections, electrical safety in the grow room is similar to electrical safety in other environments: Don’t daisy-chain multiple power strips off of one another, for example. Be mindful of your circuit capacity, and don’t confuse your lighting equipment’s output equivalency for its actual power draw.

Perform monthly inspections of all electrical equipment and wiring, looking for signs of wear or damage.

5. Develop a Chemical Storage Protocol

Proper chemical storage and handling are essential to prevent spills, contamination, and exposure to toxic substances. 

Establishing a clear protocol, including a spill response plan, and reviewing it quarterly with the team minimizes the risk of accidents. Make sure that all new hires are aware of this protocol from the jump, too.

Proper chemical storage safeguards both employee health and the grow room environment.

Create a chemical storage and handling protocol, including a spill response plan, and review it with the team quarterly.

6. Stretch! (Seriously)

Consider a group stretch at the start of each shift. Ergonomic practices like that help prevent musculoskeletal injuries common in cultivation tasks that involve repetitive motion or prolonged standing. Your team is your most important asset; make sure they’re in top shape.

This simple yet effective routine can significantly reduce the incidence of work-related discomfort and injuries, enhancing productivity and employee satisfaction. This can be a simple way to add some fun team bonding to each day’s work.

Stretching can also elevate team morale. The high-demand nature of cannabis cultivation can place significant stress on employees, potentially impacting their mental health and productivity. Establishing a supportive workplace culture through simple activities that encourage a pause in the workday hustle can also prevent burnout in addition to  enhancing team morale.

Implement a 15-minute group stretch for the team at the start of each shift to reduce the risk of musculoskeletal injuries.

7. Prepare for Emergencies

You never know what can happen in a dynamic environment like your grow rooms. 

Conducting emergency response drills, including fire evacuation and first-aid scenarios, is critical to ensure staff are prepared for potential emergencies. 

These drills, ideally held twice a year, help familiarize the team with emergency procedures, improving the speed and effectiveness of the response to actual incidents, thereby minimizing potential injuries and damage.

You can get more specific with this training, too, down to the individual level. Conducting regular first aid training and emergency response drills empowers employees to act quickly and effectively in case of accidents, injuries, or health emergencies. Having a well-trained team can make a critical difference in minimizing the impact of such events, making this an essential component of any safety program. Making first aid kits easily accessible throughout the cultivation facility and ensuring that all employees know how to use them is also crucial.

Hold emergency response drills twice a year, and make sure your first aid kits are well stocked and easily accessible.

8. Place Sanitation at the Heart of Your SOPs

Daily end-of-shift cleaning routines for all tools and workspaces are essential for preventing the spread of pests and diseases within the grow facility. This might seem obvious, but it helps to put those routines on paper–and to communicate them clearly to all team members. This regular sanitation practice maintains a clean and safe environment for plants and people alike. It’s also good habit formation practice, which can encourage greater awareness of safety precautions throughout the rest of the facility. 

Establish daily end-of-shift cleaning routines for all tools and workspaces to maintain a hygienic environment.

9. Ramp Up Security

Regular audits of access control systems ensure that only authorized personnel can enter sensitive cultivation areas. This practice will safeguard against theft, contamination, and unauthorized entry. 

Rigorous security measures maintain the integrity of the cultivation process and protect valuable genetic material.

Audit access control systems quarterly to ensure only authorized personnel can enter cultivation areas.

10. Communicate With Your Team

Monthly safety and operations training sessions keep the team informed about the latest cultivation techniques, safety protocols, and regulatory compliance. Although those topics may not change monthly, each one involves a great deal of detail. Minor aspects of safety protocols or regulatory language can be overlooked as time goes on, so frequent communication is important to keep them top-of-mind.

Ongoing education empowers employees with the knowledge and skills to perform their tasks efficiently and safely. This fosters a proactive and safe workplace culture for all. 

Organize monthly safety and operations training sessions to keep the team updated on best practices and safety protocols.

4 Strategies for Even Light Distribution in Vertical Grows

4 Strategies for Even Light Distribution in Vertical Grows

Pipp Horticulture at Culta

The Right Lights for Your Grow

Any cultivation business’s expansion into vertical farming is a complex challenge. One of the main goals is to achieve optimal light distribution on each level of the grow. 

We  are here to address the interplay between light physics, plant physiology, and technological innovations. Those elements work together to deliver light to the tiers in your grow room, and it’s on your team to ensure that the light falls evenly and helps all plants grow as healthy as possible. 

Before we get going, is your business considering an expansion to a vertical environment within your facility? We’ve got helpful tips for building out a multi-tier grow

Light Physics in Plant Growth

Pipp Horticulture at CultaThe Inverse Square Law

At the heart of understanding light distribution lies the inverse square law, which says that light intensity decreases proportionally to the square of the distance from the light source. This means that light gets weaker the farther it travels from the source, and this weakening happens faster than you might expect.  This principle is important to understand in vertical grow environments. In vertical rooms, the variance in distance between light sources and plant canopies across tiers can lead to significant disparities in the actual amount of light received by plants. The measurement here is photosynthetic photon flux density (PPFD), which conveys how much light that’s actually used for photosynthesis is hitting a given square meter of space every second. You want an even PPFD across your room.  Growers can and should use mathematical modeling to predict intensity falloff and adjust light placement and intensity accordingly, ensuring more uniform PPFD across all tiers.

Light Intensity and Canopy Dynamics

Diving deeper, the Beer-Lambert Law provides a framework for understanding how light is absorbed and scattered within the plant canopy.  This absorption, influenced by the actual number of leaves on a plant, significantly affects the light available to lower canopy levels. By trimming and shaping the plants, you can make sure light reaches all levels, especially in tight, vertical growing spaces. Watch your plant’s leaf area especially up top, closer to the light source.

Lighting Technologies for Precision Cultivation

Pipp Horticulture at CultaTailoring Spectra with LEDs

The rise and advancement of LED technology has allowed growers to focus on precision in the garden. LEDs let growers manipulate light spectra to influence plant growth and development. 

By adjusting the spectral output, growers can elicit specific plant responses, optimizing growth rates, morphology, and secondary metabolite production (think THC, for instance, or a terpene like myrcene). Implementing LEDs with adjustable spectrum capabilities allows for dynamic light management tailored to different growth stages or specific plant strains.

Pulsed Lighting: How to Enhance Photosynthesis Without Adding Thermal Stress

Pulsed lighting has the potential to increase photosynthetic efficiency by delivering high-intensity light in short bursts, reducing thermal stress on plants. 

This technique, based on the understanding of photosynthetic saturation points and non-photochemical quenching, can be particularly beneficial in vertical setups where managing heat accumulation is a challenge. Consider running a trial on pulsed lighting with an R&D crop.

Architectural Design and Cultivation Techniques

Pipp Horticulture at CultaOptimizing Vertical Rack Design

The structural design of vertical racks should facilitate spatial efficiency and optimal light exposure. Both goals should be top-of-mind when implementing a new racking system.  Incorporating inter-reflective materials and strategic geometry can amplify light reach and uniformity. Choosing materials that scatter light instead of reflecting it directly can prevent bright spots and make sure light is spread out more evenly. Consider matte white paint, white plastic, or fabrics, and foils designed for grow rooms; these materials help bounce light around the grow space more evenly than shiny, mirror-like surfaces.

Advanced Canopy Management for Uniform Light Absorption

Techniques such as apical pruning, lateral spreading, and the implementation of rotational systems ensure that all plants, regardless of their position, receive adequate light.  Leveraging plant phototropism by periodically adjusting light source positions can promote more uniform growth across the canopy. By doing so, your team makes use of plants’ natural tendency to grow toward light sources, helping them grow evenly. Tune into Cultivation Elevated Episode 17, while host Michael Williamson sits down with Corinne Wilder, VP of Global Commercial Operations at Fluence, to discuss how LED technology has shaped vertical farming.

Integrating Supplemental Lighting and Precision Monitoring

Pipp Horticulture at CultaAddressing the Lower Canopy Challenge

The deployment of side and intracanopy lighting addresses one of the primary challenges in vertical cultivation—ensuring sufficient light reaches the lower tiers. These systems must be carefully calibrated to complement top lighting, avoiding over-saturation and ensuring that light intensity and quality mimic natural conditions as closely as possible.

Harnessing Data for Light Optimization

The implementation of advanced light sensors and environmental control systems enables real-time monitoring and adjustment of light conditions. Data analytics can be used to fine-tune lighting schedules, intensities, and spectra, based on the dynamic needs of the crop and the specific characteristics of the vertical environment.

Navigating the Future of Light Optimization in Vertical Cultivation

As the science of cannabis cultivation evolves, so do the strategies for optimizing light distribution in vertical farming systems. 

The integration of advanced lighting technologies, strategic architectural design, and precise cultivation practices offers a pathway to maximizing yield, efficiency, and product quality in these complex environments. 

Growers equipped with a deep understanding of the scientific principles governing light and plant interactions and a willingness to embrace technological innovations are well-positioned to lead the charge in this new era of cannabis cultivation.

European Cannabis Laws: What Is the Latest?

European Cannabis Laws: What Is the Latest?

Pipp Horticulture at Trichome

Where Is Cannabis Legal in Europe?

In mid-February, Ukraine President Volodymyr Zelenskyy signed into law a medical cannabis legalization measure. It was just the latest in a series of incremental cannabis reforms dotting the European landscape. 

Pipp Horticulture at CanneraldUkraine’s medical cannabis law will take effect later in the summer of 2024; in the meantime, Parliament will draft more specific regulatory language. Imports will be a critical source of the country’s cannabis supply, echoing other European countries’ paths to a legal market.

As the global perspective on cannabis continues to evolve slowly but surely, Europe emerges as a promising frontier for businesses.

With a patchwork of regulatory environments and an increasing acceptance of medical and adult-use cannabis, Europe presents opportunities and challenges for industry stakeholders looking across the pond.

Statista Market Insights places the expected 2024 value of the European cannabis market at US$10.2 billion–with a growth rate on the order of 14.32% over the next five years. 

Tune into Cultivation Elevated Episode 22, while host Michael Williamson sits down with Sia Baneei of Grow Motion, a Swiss cannabis cultivation company, to delve into the intricate world of the European cannabis industry.

For cultivators and retailers who have experienced the dynamic growth of the cannabis industry in the U.S., the European market may be the next big venture. Let’s explore the landscape of the emerging cannabis marketplace in Europe, highlighting the potential for growth, regulatory considerations, and how businesses can position themselves for success in this new terrain.

European Cannabis Laws: An Overview

Europe’s cannabis market is in a state of flux, with countries at various stages of legalization and acceptance.  Nations such as Germany, the Netherlands, and Portugal have made significant strides in cannabis reform, setting the stage for a burgeoning industry. Let’s take a tour. 
Pipp Horticulture at Trichome

Germany

Germany made global headlines in late February when the lower house of Parliament legalized adult-use cannabis in a limited capacity, the first legalization measure of its kind for a country of this size in Europe (Germany follows Malta and Luxembourg in legalizing cannabis on the continent). 

The vote clocked in at 407-226, and arrived only after several years of ping-pong between a hardline “no” stance on legalizing cannabis and a willingness to draft actual regulatory language. In 2024, the willingness to open the door to cannabis reform won out.

While cannabis will be legal for those 18 and older (and legal to grow), lawmakers declined to take up a taxed-and-regulated marketplace for now. The legislation does allow for cannabis “clubs,” which will provide a space for up to 500 members to buy cannabis grown at home by other adults. 

Health Minister Karl Lauterbach said the broader idea in Germany is to “fight the black market” and provide a measure of safety to cannabis use. “Whatever we do, we can’t carry on like this,” he told lawmakers, according to the Associated Press. “You can stick your head in the sand … but we won’t solve a single problem that way.”

Germany came into this year a leader in medical cannabis already, having legalized it in 2017. The country established a government-controlled system for cultivation, prescription, distribution, and imports, creating a significant market for medical cannabis products and associated equipment.

The Netherlands

Known historically for its liberal stance on cannabis, The Netherlands has tended to informally allow the sale of cannabis in coffee shops. In recent years, lawmakers have kicked the tires on plans to regulate the supply chain more formally. 

The state launched a pilot program to legalize the sale of adult-use cannabis  in December 2023, greenlighting coffee shops in the cities of Breda and Tilburg to sell cannabis grown by one of two licensed cultivators.

That marks the second European country to embark on a pilot program. The first country was… 

Switzerland

Switzerland arranged a trial program for adult-use legalization in 2023. The country’s Federal Office for Public Health initially greenlit six pilot projects (three of which are already selling cannabis legally to Swiss citizens). More of those projects are expected as the program picks up momentum.

A federal commission stated in 2023: “Cannabis must be controlled, legally accessible, but not be promoted.” That’s a fine line to walk for small businesses interested in growing an audience and developing a brand.

“The cannabis business in Europe is very, very difficult,” Grow Motion’s Sia Baneei said in a recent Cultivation Elevated podcast episode. Grow Motion is a licensed cultivator in Switzerland’s high-CBD cannabis market. “We live in Switzerland, and the rent for our facility is very, very expensive. That’s why we wanted to get the maximum of our facility and why we made the decision to work on three layers [in a vertical farming room design].”

That’s another challenge that businesses will face in Europe, perhaps more so than in areas in the U.S.: Real estate is at a premium, and industrial space is simply more limited than it is in the rural stretches of, say, the Ohio cannabis market. A mobile vertical racking system can go a long way toward maximizing grow space while maintaining safe and easy access to plants, solving critical needs in cramped quarters.

Portugal

Having decriminalized all drugs in 2001, Portugal has taken steps toward a regulated medical cannabis market and is seen as a potential hub for cultivation due to its favorable climate. Companies of all sizes have set up shop in Portugal, using the state as a formidable base of operations for corporate headquarters and cultivation sites. 

As of the end of 2023, the majority party in the federal government was developing a task force to closely look at cannabis legalization prospects. That party is not alone; support for broad legalization measures has increased across the government in recent years. 

Somai Pharmaceuticals founder and CEO Michael Sassano told Business of Cannabis, “Discussions like Portugal’s decision to move forward with studying to legalizing adult-use cannabis and other discussions around legalizing medical cannabis are being taken up by most EU countries more progressively than ever before. Much has to do with the potential U.S. rescheduling to Schedule III and the German descheduling of a narcotic. Global winds are changing fast, and Portugal is still very much at the top of the list as a potential new country moving towards legalizing cannabis”.

The Czech Republic

The Czech Republic announced its intention to legalize cannabis, but that plan does not include any real tax-and-regulate system that would allow sales. The country decriminalized possession for personal use in 2010, meaning that this current plan would effectively reiterate the status quo and apparently add provisions for cannabis use in social clubs. After a show of political support for a regulated market from some political leaders, this “compromise” plan leaves licensed corporations and suppliers mostly on the sidelines. That said, we anticipate more information to come in 2024. 

The lack of a formal market structure will be hotly debated this year. 

“The existence of a commercial and strictly regulated market with licensed growers and stores is a basic prerequisite for the successful reform of anti-cannabis laws, as is evident all over the world – from Colorado to California to Canada or Switzerland and the Netherlands,” CzecHemp manager Lukáš Hurt said in a translated press release. “Thanks to regulation, it is possible to significantly reduce the revenues of the illegal market and at the same time obtain funds for effective drug prevention and education.”

France

France began a medical cannabis experiment in 2021, offering free products to thousands of patients. The trial program was expected to sunset in the spring of 2024, but for now, the Minister of Health is open to a plan that will gradually transition that arrangement to a more formal (yet still “temporary”)  medical cannabis regulatory structure for the next five years. 

This plan is in flux, so we anticipate learning more soon, but France has shown a willingness to broaden its access and industry sophistication with this news. 

The UK

While not a member of the European Union, the UK has also made strides in step with its neighbors. Following its 2016 departure from the EU, the UK legalized an extremely tightly regulated medical cannabis program; the UK’s National Health Service has not developed this program much further than allowing limited prescriptions.

That said, the industry is livelier in the UK than it might seem; the country ranks among the largest exporters of medical cannabis products in the world. 

Across Europe, the recent shifts towards decriminalization, and even recreational legalization in some jurisdictions, signal a broader change in societal attitudes towards cannabis. 

This evolving regulatory landscape presents a fertile ground for innovation and investment but requires a nuanced understanding of each country’s legal framework.

Navigating Regulatory Complexities

The demand for medical cannabis in Europe is on the rise, driven by an increasing body of research supporting its therapeutic benefits and a growing awareness among the population. This uptick in demand signals a burgeoning market for cannabis-related products and business solutions.

Pipp Horticulture at CanneraldHowever, the path to expansion is not without its hurdles. International treaties and the U.S.’s own complicated relationship with cannabis will complicate any expansion plans for growers or retailers with an eye toward Europe.

The continent’s diverse regulatory landscape means that what works in one country may not apply in another. For businesses looking to enter the European cannabis market, understanding and navigating these regulatory complexities is paramount.

Compliance with local laws and standards for the cultivation, storage, and distribution of cannabis products is critical, underscoring the need for adaptable and compliant solutions. To succeed in Europe, suppliers must tailor their offerings to meet the specific needs and regulations of each market.

5 Best Practices for Your Cannabis Mother Room

5 Best Practices for Your Cannabis Mother Room

Pipp Horticulture Cannabis Mother Room

Be Good to Your Mother(s)

Your indoor cannabis cultivation facility is operating within a highly competitive market. While the point of harvest may seem like the most important link in your production process, you may want to revisit the management of your cannabis mother room. That’s where your business houses its real long-term value. 

The mother room is where your team nurtures the mother plants, which, of course, shape the future of every plant you’ll grow. These mother plants are carefully selected cannabis plants kept in a vegetative state and not allowed to flower. The primary purpose of maintaining these mother plants is to provide a consistent and reliable source of clones or cuttings. These clones are genetically identical to the mother plant, ensuring uniformity in the traits and quality of the plants grown from them, such as potency, flavor profiles, and growth characteristics.

An efficiently managed mother room ensures a steady flow of high-quality clones to fill the other rooms in your facility. 

Your yield and profits begin here.

Mother Room

A successful mother room strategy blends the precision of genetics with the art of cultivation, ultimately developing a shield for your business against the unpredictability of nature. In a market that values both diversity and the reliability of old favorites on the shelf, the ability to sustain and replicate specific cannabis strains with accuracy is invaluable.

So, what goes into a successful cannabis mother room?

A robust mother room operation employs advanced environmental controls, precise nutrient management, and rigorous hygiene protocols to ward off pests and pathogens, ensuring that each clone represents the best possible start for the next generation of plants. We’ll explain five helpful best practices to bear in mind below.

These tips will streamline your team’s cultivation process and cut back on the risk of crop failure. This level of control and efficiency translates into faster turnaround times, higher yield potential, and improved product consistency, ultimately contributing to a stronger market position. 

The success of a commercial indoor cannabis cultivation business is intricately linked to the performance of its mother room.

[#1] Double-Stacked Cannabis Mother Room Racks

Let’s get into the actual layout of your cannabis mother room. How are these plants supported? Where are they located within the room?

More often lately, our team has seen cultivators double-stacking mother plants and maintaining them for shorter lifespans (as opposed to running a single-level layout with plants that might be sustained for longer time periods). Some cultivation businesses might prefer to hold onto mother plants for upward of a year or more, but the shorter lifespan encourages more supple cuttings and a more agile cultivation team in general. This also limits the risk of pest and pathogen spread. 

In a 2023 webinar, Pipp’s Director of Horticulture, Anders Peterson said that double-stacking has proven benefits.

Pipp HorticultureGenerally, I’ll keep my younger mothers on the top level, which is typically a shorter elevation, as far as its height,” he said. “The bottom elevation, which will be taller in height, … can hold my more mature mothers.” 

Maintaining younger mother plants in your cycle balances the diversity of the room and allows for higher quality: We’ve noticed grow teams getting a significant increase in “A-grade” cuttings versus the older mother plants. Double-stacked mother rooms help house additional genetics in a smaller space, allowing you to allocate square footage for flower production.

There’s a balance, of course, in serving the market with tried-and-true genetics that will sell easily and providing dispensaries with more cutting-edge cultivars that might be a bit more experimental or nuanced in their demand curves. A diverse, double-stacked mother room lends some of that flexibility to your business.

PRO TIP: Good ventilation is essential to prevent microclimates within the tiers. Use oscillating fans and ensure your room's HVAC system is capable of circulating air effectively throughout the stacked racks. Proper airflow helps to maintain consistent temperature and humidity levels across all levels, minimizing the risk of mold and pests.

[#2] Optimal Environmental Conditions

Pipp HorticultureYour facility runs on the efficiency of its environmental control system, but you must add a layer of redundancy by personally checking on the actual variables (temperature and humidity, foremost) on a regular basis. Automated systems are fine and increasingly prevalent, but your team should not solely rely on them. The value of the plants in your cannabis mother room is simply too great. Reliable handheld sensors (for variables such as temperature and relative humidity, among others) can be used to double-check and verify the automation and control platform data.

This may go without saying, but it’s worth underscoring the importance of daily touchpoints with your mother plants. In between cuttings, the maintenance of your plants is absolutely critical. 

Keep your mother plants in veg by maintaining an 18-hours-on/6-hours-off lighting schedule. Inspect and clean all light fixtures to ensure optimal output–and do whatever you can to prevent light leaking in from the hallway. In fact, implement a rotation schedule for light bulbs to maintain consistent light intensity and spectrum. 

That point about equipment maintenance is especially important in your mother room. Here’s a quick checklist of items you’ll want your team to manage on a clear, regular basis:Pipp Horticulture

  • Check the efficiency of your ventilation system on a regular basis. Effective air circulation is the backbone of maintaining stable temperature and humidity levels in your mother room, (i.e., maintaining stable genetic lines!) and warding off mold and pests. Change your HVAC filters on a regular basis.
  • Check the sensors in your mother room to ensure accurate temperature and humidity monitoring. This goes back to that idea of redundancy and the human touch; you can’t rely solely on your automated data feeds. To maintain the accuracy of these systems, regular calibration should be part of your maintenance schedule as well. This ensures that your plants are always growing in the ideal conditions they need for optimal health.
  • Check on your airflow system in this room. If your ventilation system is in good shape, your fans will achieve even air distribution for your mother plants, keeping their veg cycles in a state of stasis. If you’re looking to give your plants an extra boost, consider implementing a CO2 enrichment system. This step requires the ability to closely monitor and control CO2 levels to avoid any potential harm to your plants.Pipp Horticulture
  • Establish a consistent watering schedule that’s responsive to the visual cues your mother plants give you. Paying close attention to their appearance and growth stage will guide you in adjusting their water and nutrient intake. 
  • To that end, daily inspections of your mother plants are critical. Be on the lookout for any signs of stress, pests, or disease. Regular pruning not only helps in controlling plant size and shape but also encourages healthy growth.
  • Lastly, do not overlook nutrient management in your mother room. Each strain and individual plant may have its own specific nutritional needs, and that’s paramount to the proper maintenance of the genetic line. By implementing a tailored feeding regimen and regularly testing the soil or hydroponic solution for nutrient content and pH levels, you can adjust your feeding strategy as necessary. Early detection of nutrient deficiencies or excesses, along with prompt treatment, is fundamental in maintaining the health and productivity of your mother plants.

[#3] Strict Sanitation and Hygiene Protocols

Pipp Horticulture Cannabis Mother RoomPerhaps more than any other room in your facility, the sanitation of your cannabis mother room is of critical importance. This is your genetic bank vault, after all.

Set up a daily surface cleaning routine for this room, and keep your team members up-to-date on SOPs. This includes entry protocols (and possibly uniforms and footbaths). 

On that topic: While we all enjoy giving tours to curious news media and to interested stakeholders, you should never tour visitors through a mother room. Allow only a limited number of staff into your mother room. Protect it at all costs!

Use only one pair of pruning shears per mother plant, and don’t cross-contaminate them. The risk of hop latent viroid (HpLVd) is ever-present in facilities, and a pathogen like that could decimate your mothers (and thus your bottom line). Regularly sterilize all pots, trays, and other equipment used in this room. Any equipment relating to the mother room should not be used anywhere else in your facility.

To ensure a sense of uniformity across your plants and across time, develop a pruning schedule to manage plant size and shape. Training team members in proper pruning techniques is crucial to ensure they promote healthy growth without stressing the plants.

That pruning plan leads us to…

[#4] Cloning Procedures and Record Keeping

Pipp HorticultureCloning: where the true magic happens in your facility.

Follow a consistent cloning schedule, and make sure you’re building this schedule on sound reasoning (take your six-inch cuttings and rootings at the right time to maintain plant health). Document all records associated with each plant and its clones. Those records will inform later improvements in your mother room.

Observe the quality of those clones over time. How are they performing as they move through growth cycles? Those plants’ health will help you understand your mother plants’ health. Investigate and address right away any declines in cloning efficiency or quality.

PRO TIP: Implement regular data backup procedures to prevent loss of valuable genetic and cultivation records. Ensure that your digital tracking system has robust security measures in place to protect sensitive information and comply with regulatory requirements.

[#5] Regular Training and Education

Lastly, like most other activities in the cultivation space, work in the mother room is an ongoing education. Encourage your team to stay informed on the latest cultivation and genetic trends in cannabis.

Even in cultivation team meetings that don’t specifically address the mother room on the agenda, try to connect what’s happening in the mother room to broader developments in the business. Make sure that all employees are aware of what genetics you’re maintaining.

Coordination with the flowering team and sales staff is crucial for managing a cannabis mother room; you don’t want to be cutting clones of a cultivar that is not selling, or for a cultivar that is piling up in your finished product storage room. 

Mother rooms dictate the flow of product to the rest of your facility and ultimately to your sales channels.

The mother room team can greatly influence the culture of your business; and promote a culture of shared knowledge across the facility. Make sure that your mother room team is keeping other cultivation teams informed on any changes at the individual mother plant level.

How to Build a Flower Room For an Indoor Cannabis Facility

How to Build a Flower Room For an Indoor Cannabis Facility

Pipp Horticulture

What You Need To Know About Your Cannabis Flower Room

The flower room is the soul of the indoor cannabis facility. It’s where all tours with business partners and excitable local press corps members ultimately culminate, garnering wide-eyed looks of excitement. It’s where all the best traits of a cannabis cultivation company are on display. But those moments only scratch the surface of those rooms’ capabilities. The flower room is where a cultivation business turns plant material and ambition into revenue and growth.

Pipp HorticultureWhile “yield” has remained a cornerstone metric for cultivation businesses’ success since the dawn of the industry, this basic fact is only becoming more pertinent. Price compression, oversupply, rapidly evolving consumer demand trends: There are factors at play that demand new efficiencies coming out of the flower room. Yield is more important than ever, and your team can achieve great metrics by dialing in flower room design and operations. The design phase is a perfect opportunity to consider your broader flower room strategy, of course, but you can implement new efficiencies as you learn more about what works for your business. 

So, what sets any cannabis flower room apart from one another? Aside from the people working in those rooms, there are several fundamental aspects of good flower room design that must be accounted for in the early planning stages–and optimized on a regular basis once operations have commenced.

Consider:

  • Spatial Configuration and Plant Density
  • Integrated Environmental Control Engineering
  • Proper Air Flow and HVAC
  • Light Mapping and Design
  • Irrigation and Fertigation Infrastructure

Get those core concepts wrong, and your team will miss out on opportunities for stratospheric growth and output. Get them right, though, and you set yourself up for success. After all, what comes out of your cannabis flower room is all about what goes in. 

Spatial Configuration and Plant Density

Pipp HorticultureEnvironmental controls, efficient HVAC equipment, sufficient lighting: We’ll get into those technological aspects in a moment. Even more important than your software and hardware, however, is the actual floor plan of your flower rooms. People need to walk through these rooms scouting plants, cutting down plants, transporting plants, and ultimately turning over the room entirely for the next cycle. That’s a lot of movement! And your plants must be spaced evenly to ensure healthy, consistent growth and optimal yield for your business. You want to get the most out of your room, but not to the detriment of individual plants’ health. Your airflow and lighting plans will have given you a good base from which to arrange the actual benching in your flower room. How many plants can you sustain, given your equipment?

Consider mobile vertical racking systems to maximize this density while preserving the room’s foot traffic flow. You won’t waste an inch of space by adding mobile carriages  to your vertical racks, which eliminates fixed aisles between each rack. Mobile carriages will also provide a degree of flexibility when it comes time to expand your canopy or revisit your floor plan outright. Even the best-laid plans in indoor cultivation will be amended as your team hones their operation. By investing now in a more mobile solution, you’ve just bought yourself some serious room to grow in the future.

Plan to fill out those vertical racks with grow trays that allow you to seamlessly connect the technology that we’ll get into in a moment: your lights, your airflow, your irrigation. Picking the right grow tray might seem like a small step, but it’s a fundamental part of your workflow.

PRO TIP: Different genetics result in different phenotypes. If you’re considering a fairly diverse portfolio of cultivars, implementing  vertical racking will allow you to place smaller plants higher, leaving more room on lower racks for taller plants. This height disparity can get very tricky when you’re managing airflow and lighting across a single plane of benches.

Integrated Environmental Control Engineering

It’s not enough anymore to have functioning environmental controls. The competitive nature of the cannabis marketplace insists that operators implement some form of integration and automation into their systems. Your team needs real-time data. As you design and build your flower rooms, you must plan for this integration.

Pipp HorticultureThe cornerstone of a successful cannabis flower room is its environmental control system. We’ll get into the specifics of HVAC, lighting, and irrigation shortly, but first, we must point out the importance of linking these technologies. Automation and data analytics go hand in hand with the actual horticultural practices of your flower room. 

Your team will be in and out of your flower rooms, scouting individual plants, but so too will your environmental control systems analyze real-time data and identify trends among your crops. How are your plants responding to subtle changes in lighting or airflow? Which individual plants are receiving too much or too little light at a given moment? That data, as one minor example, is critical to understanding your flower room. By leveraging this data, growers can fine-tune their environmental parameters for optimal yield and quality.

So, where should your team begin? Develop your flower room design around programmable logic controllers (PLCs) that automate environmental inputs on a real-time basis. Ensure that your sensors are appropriately placed around the room to provide those PLCs with a comprehensive data set. Most data collection can also be conveyed via a given software provider’s app, allowing you and your team immediate access to real-time data and, of course, to sudden emergencies. This data can and should inform your cultivation decisions. Understanding that app should be an important part of your cultivation team onboarding process.

Every plant coming out of your flower room represents a small portion of your company’s bottom line. The data you’re receiving about how those plants are growing can help your team make decisions about what to grow and what to sell (and when to sell). This data collection allows a savvy cultivation team to draw a competitive flower room edge.

Proper Airflow and HVAC

Pipp HorticultureAirflow is critical to a cannabis flower room, where microclimates lurk and threaten the health of your plants. This is especially true in a vertical growing environment. While all inputs are critical in your flower room, airflow may be the one variable that can be the most limiting if you fail to execute for your facility’s and plants’ needs. 

Good air circulation can go a long way toward preventing the spread of more nefarious problems like pests and pathogens. Your HVAC system must exchange the air in your flower room several times per hour, balancing clean oxygen and CO2 levels for optimal plant growth. This means that your HVAC system will be working constantly in the background, so efficiency in your hardware is key.

Use HEPA filters in your ventilation system to remove any airborne pathogens. Indoor cannabis cultivation spaces, no matter the square footage, must be paragons of cleanliness and sanitation. If you’re designing a room as part of a new build, you can incorporate this from the start. 

Retrofit projects come with much more pressure on this particular point. Make sure the actual room you’re planning as a future flower room has the HVAC and ventilation capabilities to house flowering cannabis plants safely. Always bear in mind that we’re talking about plant material grown for human consumption. 

WANT TO LEARN MORE? Vertical Air Solutions’ patented In-Rack Airflow System provides uniform airflow in a multi-layered rolling rack platform.

Establish a regular maintenance schedule to keep that ventilation system as clean as can be. Delegate specific maintenance responsibilities to team members on a rotating basis so that everyone can dial in their understanding of the system. When it comes to energy efficiency, HVAC is one place where you can really invest for long-term savings. Work with your equipment provider to identify energy-efficient units and map out the cost of those units over time.

PRO TIP: Manage heat load from other pieces of equipment (more on lighting in a moment) and measure the capacity required to maintain a consistent temperature and humidity level in the room. Variable-speed fans can provide the flexibility needed to maintain those levels throughout the day.

Light Mapping and Design

Lights get the spotlight in cannabis cultivation, and perhaps deservedly so. A good cannabis flower room design will include light mapping projects as the buildout gets underway–and well into operations. Where will you place your light fixtures for optimal plant growth? How will you know which setup is ideal for your crop?

As you’ve noticed thus far, a keyword in flower room design is “consistency.” You can use software to map a room’s light intensity. This will give you a more refined picture than simply using your own eyes to gauge your room’s setup. You need to understand how much light a given plant is going to receive from all light fixtures that “touch” it. These programs coordinate each spot’s given light intensity by measuring light from as many as nine angles around the plant. This will give you a better sense of the uniformity of your light distribution. Much like you can avoid microclimates with uniform airflow, you can avoid hot spots with uniform lighting. 

Get familiar with the calculator for photosynthetic photon flux density (PPFD) and ensure that you’re covering the canopy. Within that coverage in your flower room, you want to recreate the sun’s own diurnal rhythm as closely as possible. While your veg room will operate on something close to an 18/6-hour cycle, your flower room will be on a 12/12-hour cycle of darkness and light. (Consider, too, the potential power of inter-canopy lighting.)

PRO TIP: Be mindful of light pollution streaming in from hallways. It might not seem like a big deal when so many more consequential investments are being made early on, but photons leaking in from the hallway can have an outsized impact on your plants’ health. As an added precaution, consider using green light spectra (near 530nm) in the hallway outside your flower room(s) to limit any problematic spillover effects. 

Irrigation and Fertigation Infrastructure

Freedom GreenIrrigation and fertigation are critical aspects to your flower room design and to the finished flower you’re harvesting. Perhaps nutrient recipes are more proprietary than light maps. Nonetheless, anyone working on designs for a new indoor facility’s flower rooms or for a series of retrofitted flower rooms must consider the source of water and the delivery of that water (and those nutrients).

Once again, consistency will drive this facet of your flower room plan. Automated drip irrigation systems or hydro setups can deliver uniform amounts of water and nutrients to each plant with minimal interruption to the floor plant mentioned in the previous section. You don’t need hoses lying around your flower room; you need solutions. 

Within those systems, make sure your environmental controls include monitoring of pH and electrical conductivity (EC) to continue that consistent nutrient delivery. Overwatering, underwatering: Nothing good comes from being imprecise with your irrigation system. 

Cannabis Flower Room Efficiency Checklist

  1. Pipp HorticultureRegularly check and maintain the HVAC and ventilation systems to ensure the CO2 supply is working correctly. Systematize this process as part of your team’s SOPs.
  2. Inspect your lighting fixtures, first through your environmental control data and then by physically examining any units that need maintenance. Clean them regularly.
  3. Same with your fan units: Keep the room’s air moving efficiently by maintaining fans and air filters regularly.
  4. Maintain a highly detailed sanitation protocol.
  5. Ask your cultivation team members what they think about the literal floor plan: How easy is it to get their jobs done within the flower room(s)?
  6. Check your irrigation and fertigation systems for any unexpected issues, and ensure your plants get the right amount of nutrients.
  7. As a senior-level management team, periodically review how well your flower room is running and look for ways to save energy and resources.
  8. Ensure all team members are well trained in your company’s flower room safety SOPs and regularly review and update operational procedures.

5 Things US Cannabis Operators Need to Know About GACP & GMP

5 Things US Cannabis Operators Need to Know About GACP & GMP

Pipp Horticulture

Setting the Standard

Good Manufacturing Practices (GMP) are vital quality assurance standards ensuring product consistency and safety across industries. They prevent errors, safeguard worker health, and protect the public. GMP is essential in pharmaceuticals, food, cosmetics, and more. This blog explores GMP principles, the absence of GMP guidelines in the US cannabis industry, and how businesses can prepare for future regulatory changes. We’ll also discuss GMP’s influence on architectural design and introduce Good Agricultural and Collection Practices (GACP) for medicinal plants, emphasizing GMP’s continuous pursuit of manufacturing excellence.

1. What is GMP?

GMP, or Good Manufacturing Practices, is the quality assurance process in product production that ensures product consistency and quality. GMP guidelines and compliance are critical for quality assurance, worker safety, and protecting human health. GMP prevents errors and inconsistencies that cannot be eliminated through quality control of the finished products and consumer goods. With GMP, it is possible to be sure that every unit of medicine or consumer goods manufactured is of the same quality as the units of medicine tested in the laboratory.

Key Principles of GMP:

  • Creation and enforcement of Standard Operating Procedures (SOPs).
  • Comprehensive documentation of all procedures and processes.
  • Validation of SOP effectiveness.
  • Development and implementation of efficient working systems.
  • Development of employee competencies.
  • Regular maintenance of systems, equipment, and facilities.
  • Prioritizing cleanliness to prevent contamination.
  • Ensuring quality is central to the design, development, and manufacturing workflow.

2. Why are there currently no GMP guidelines for cannabis in the United States?

In the United States, the Food and Drug Administration (FDA) recommends guidelines for anything food, cosmetics, drug, or pharmaceutical-related. These guidelines consist of processes, procedures, and documentation that ensure manufacturing consumer goods are consistently produced and controlled according to set quality standards. Unfortunately, as the federal law currently states, the use, sale, and possession of cannabis containing over 0.3% THC by dry weight remains illegal as a Schedule I drug type under the federal Controlled Substance Act of 1970, despite laws in the majority of states that have enacted legislation permitting exemptions for various uses, including medical, industrial and recreational use. 

Because cannabis is currently a Schedule I drug type (sadly, the same category as Heroin and MDMA), federal agencies, such as the FDA, have not developed GMP guidelines for licensed and compliant cannabis operators. As a result, state lawmakers and cannabis business owners are forced to navigate this new and rapidly evolving industry without any standardized guidelines. 

On August 29, 2023, the Department of Health and Human Services (HHS) recommended rescheduling marijuana from Schedule I to Schedule III under the Controlled Substances Act (CSA) to the Drug Enforcement Administration (DEA). However, in the near term, this recommendation is unlikely to significantly impact the cannabis industry because the Drug Enforcement Agency must now conduct its review and decide whether to follow the HHS recommendation. It also does not legalize cannabis. State-licensed cannabis businesses will still be operating in violation of federal law. However, in the long term, the FDA could provide specific guidelines or subject cannabis to existing regulatory authority.

3. What can cannabis business owners do to be
GMP-ready as legislation changes in the future?

Cannabis operators can get critical insights into what GMP guidelines may potentially look like in the future for the US from global cannabis companies that are certified EU-GMP. Some of the differences between EU-GMP and US-GMP are that the EU-GMPs require manufacturers to have a pharmaceutical quality system (PQS), encompassing a broad range of quality management activities. The US-GMPs emphasize the establishment of a quality control unit (QCU) and use quality systems but do not have a specific requirement for a PQS.

Basic Requirements of EU-GMP:

  • All manufacturing processes are clearly defined, systematically reviewed in the light of experience, and shown to be capable of consistently manufacturing medicinal products of the required quality and complying with their specifications.
  • All critical steps of manufacturing processes and significant changes to the process are validated.
  • Appropriately qualified and trained personnel.
  • Adequate premises and space. 
  • Suitable equipment and services.
  • Correct materials, containers, and labels.
  • They approved procedures and instructions by the Pharmaceutical Quality System.
  • Suitable storage and transport.
  • Written instructions and procedures in unambiguous language tailored to the provided facilities.
  • Operators undergo training to ensure the correct execution of procedures.
  • During manufacture, operators create records manually or use recording instruments to demonstrate that they followed all steps required by the defined procedures and instructions, ensuring the expected quantity and quality of the product.
  • Any significant deviations are fully recorded and investigated to determine the root cause and appropriate corrective and preventive action implemented.
  • Manufacturers retain production and distribution records in an understandable and accessible form, enabling the tracing of the batch’s complete history.
  • The distribution of the products minimizes any risk to their quality and takes account of Good Distribution Practices.
  • A system is available to recall any product batch from sale or supply.
  • The team examines product complaints, investigates the causes of quality defects, and takes appropriate measures to prevent the recurrence of defective products.

4. How does GMP impact architectural design?

GMP can significantly influence the layout of a cultivation, extraction, and manufacturing facility and the selection of construction materials and equipment. The industrial architect must design the facility per the GMP regulations when applicable. Facility design for a GMP-compliant warehouse includes having designated areas for raw materials, finished goods, quarantine products, rejected products, etc. The warehouse must be dry, clean, and well-lit. The storage conditions shall be as per the material requirements.

Features to Incorporate in Facility Design:

  • Design and construct the facility to ensure hygienic production conditions.
  • Building materials, when applicable, should be easy to clean and sanitize.
  • There should be no way for the entry of insects, pests, birds, vermin, and rodents.
  • The facility should be spacious.
  • The facility has to be at a location where there are no fumes. The design should prevent any fumes or infestation of the product.
  • There should be covering on walls and floors, and surfaces should have cleanable surfaces.
  • The facility area should be free of cracks and open joints to avoid dust collection.
  • There should be segregation between departments and, in some cases, bio-secure vestibules for changing out personal protective equipment (PPE).
  • The facility infrastructure design should have a dedicated HVAC system based on area classification.
  • The facility should have a flexible layout.
  • The design must provide well-lit, ventilated production areas with air control facilities.
  • Design the drainage and plumbing system to prevent backflow and ensure adequate sizing.
  • Avoid open drains.
  • The construction process should not cause any negative impact on the environment.
  • The facility should have a provision for secure, hazardous, and inflammable materials as per the regulations.
  • Design a proper fire protection system.
  • Piping, electrical fittings, and other utilities should not create a recess.
  • Provide coloring and direction of flow on service lines.

5. What is GACP?

The World Health Organization (WHO) developed GACP, or Good Agricultural and Collection Practices for medicinal plants, in 2003 to enhance the safety, efficacy, and sustainability of medicinal plant material used in herbal medicines in the market. Specific to the cannabis industry, GACP consists of the practices used during agricultural production, which includes processes and procedures in the following stages: Tissue Culture, Mother/Stock, Propagation, Vegetative, Flowering, and Harvesting. Typically, the drying stage and all manufacturing after drying is where the transition happens from GACP to GMP.

Main Objectives of GACP Guidelines:

  • To contribute to the quality assurance of medicinal plant materials used as the source for herbal medicines to improve finished herbal products’ quality, safety, and efficacy.
  • To guide the formulation of national and regional GACP guidelines and GACP monographs for medicinal plants and related standard operating procedures.
  • To encourage and support the sustainable cultivation and collection of medicinal plants of good quality in ways that respect and support the conservation of medicinal plants and the environment in general.

Key Takeaway

GMP compliance is a continuous journey, not a destination. Regular audits, swift identification of potential deviations, and corrective actions are all part of this process. Embracing a culture of continuous improvement and having a team that understands and implements the principles and components of GMP are the first steps towards ensuring ‘Good’ Manufacturing Practices become ‘Great’ Manufacturing Practices.

10 Essential Tips for Creating a Controlled Environment Agriculture (CEA) Facility

10 Essential Tips for Creating a Controlled Environment Agriculture (CEA) Facility

Vertical Air Solutions

Setting up a Successful CEA Facility

Controlled Environment Agriculture (CEA) has transformed the agricultural landscape, offering innovative solutions to traditional farming challenges. As urbanization increases and the demand for locally grown, pesticide-free crops increase, CEA facilities are gaining prominence. But setting up a successful CEA facility requires careful planning and foresight. Here are ten expert tips to help establish a thriving CEA operation.

1. Create a Comprehensive Plan

Setting up a Controlled Environment Agriculture facility requires a well-thought-out approach, accounting for many factors ranging from finance to nuanced design and engineering elements. One cannot overstate the importance of a comprehensive plan in ensuring your CEA facility’s efficiency, sustainability, and profitability. Investing time and effort into crafting a comprehensive plan can be the difference between the success and failure of your CEA venture. This plan should include: 

Business Plan

Start with a thorough business plan. This Business Plan should be the roadmap that guides your journey. Understand your target market, identify supply gaps, determine the crops you plan to produce based on market demand, and research the competition. 

The business plan should outline your marketing strategy, pricing model, and sales approach. Consider external factors that might influence your business, such as regulations, competition, market fluctuations, technological advances, and environmental concerns. Building flexibility into your business plan can help you adapt to unforeseen changes.

Financial Proforma

This is a critical component of planning that will have implications throughout the operations lifecycle. A financial proforma provides projections for revenues, expenses, and profitability. Your proforma should include estimates for initial startup costs, operating costs, anticipated yields, and selling prices. You must also factor in technology costs, testing, labor, genetics, nutrients, advisors, sales and marketing, and utilities. 

This document is crucial not only for internal budgeting but also imperative when seeking external financing or investors. Remember to regularly revisit and adjust your financial proforma as real-world data from your operations flows in.

Facility Design

Designing the facility is one of the most crucial yet challenging components of setting up a CEA. Whether you’re conceptualizing an indoor vertical farm, greenhouse, or another type of CEA environment, the design should optimize space, ensure efficient and ergonomic labor, minimize utility consumption, and promote high yields. 

Consider light sources, ventilation, environmental control, pest control management, and workflow. A well-thought-out design can significantly influence the efficiency and productivity of your CEA setup. If possible, involve experts or consultants in this phase to benefit from their experience.

2. Define Your Goals

Defining clear and measurable goals ensures success, strengthens morale, and maximizes resources when setting up a CEA facility. Before diving into the technicalities, clarify your objectives. Are you aiming for a specific ROI, year-round production, specific crop production, organic, and or GMP certification? Your facility’s design, technology, and operating procedures should align with these objectives. Early in the planning stage, it is essential to identify the type(s) and volume of crops you intend to cultivate. Each crop will have unique environmental needs regarding light, humidity, temperature, CO2, and nutrients. Once you’ve identified the crop, set clear yield objectives. Your infrastructure, technology, and financial investments will largely pivot on this decision. By defining goals clearly and precisely, informed stakeholders can align to ensure their facility’s resilience, profitability, and community impact.

3. Choose the Right Location

While Controlled Environment Agriculture facilities offer greater environmental control, location still matters and can impact nearly all variables operators manage. Here are a few factors to consider:

Energy Availability

Understand your power requirements. Ensure you have access to consistent, affordable energy sources. Lack of power can significantly impede optimization or worse.

Water Quality

Access to clean water is crucial. Test water for contaminants and consider and establish a purification system based on the results.

Logistics

Proximity to suppliers and markets reduces transportation costs and ensures product freshness.

Labor Force

Ensure access to the appropriate labor force at rates within the allocated budget.

4. Plan for Scalability and Future Expansion

When planning your facility, defining your goals, and selecting a location, don’t neglect to consider scalability. Planning for scalability and future expansion in a Controlled Environment Agriculture facility is a multifaceted endeavor that can save significant time, effort, and money. Developing a modular design is a practical approach to ensuring scalability, designing, and constructing in a way that allows for easy expansion or integration of new sections. Your modular design involves conceptualizing the physical structure, electrical, plumbing, and other systems to be expandable. Operations can add new modules or zones with minimal downtime and impact on existing processes.

A scalable CEA facility doesn’t just refer to infrastructure and technology; it’s also the team operating it. Continuous training programs ensure a prepared workforce to handle expansions and adopt new technologies. Focusing on workforce development ensures that personnel are ready to take on managerial roles as the company scales. Scaling operations often require significant capital. It’s crucial to have a clear financial roadmap that outlines the resources needed for future expansions. Scaling operations may entail setting aside a portion of profits for reinvestment, exploring external financing options, or partnering with investors who understand the vision of the business. Finally, it’s essential to have mechanisms in place to gauge market demand constantly. Scalability should be in line with market needs. By establishing strong feedback loops with distributors, retailers, and end-consumers, the CEA facility can fine-tune its expansion plans to better align with market dynamics.

5. Optimize for Space

Optimizing space in a CEA Facility is paramount, given the premium costs associated and the need to maximize yields to ensure profitability. As urban farming and indoor agriculture continue to gain traction, operations are constantly searching for innovative techniques and technologies to maximize output in limited space. A groundbreaking innovation in this space is the development of mobile vertical farming racks. Mobile vertical grow racks allow farmers to utilize unused aisles and vertical space, which is particularly relevant in urban settings where horizontal space is often limited. By stacking crops on top of one another, these racks can dramatically increase yields in a fixed area and their mobility allows for additional space optimization by eliminating static aisles and improves plant maintenance, harvesting, and cleaning.

Catwalk systems are another space-saving tool for CEA facilities. They’re advantageous operations where accessing the top tiers of vertical farming racks can become a challenge. Catwalks provide growers with safe and convenient access to all vertical indoor farming setup levels. This ease of access can also speed up farming operations like pruning, scouting, and harvesting. Mobile carts have become indispensable tools in modern CEA setups. These carts are designed and customized for seeding, transplanting, or harvesting tasks. Due to their mobility, they allow workers to move seamlessly from one location to another, carrying all the necessary tools and supplies with them. Utilizing mobile carts saves space and significantly improves operational efficiency, wasting less time moving back and forth.

6. Ensure Proper Air Circulation

One of the essential components contributing to the success of a CEA facility is ensuring proper air circulation and sanitation. Efficient air movement is vital for plant health and crucial for temperature, humidity, and contaminant control, influencing crop yields and quality. The ambient airflow system is at the heart of maintaining an ideal growing environment. Ambient airflow creates a gentle, consistent movement of air that minimizes hot, cold, or stagnant spots and ensures an even distribution of heat, humidity, and carbon dioxide (CO2) around the plants. Proper ambient airflow can also help prevent the growth of mold and other pathogens by reducing the moisture build-up on plant surfaces.

When well-designed, ambient airflow systems can significantly improve plant health and productivity by creating an environment where plants can optimally perform photosynthesis and transpiration. Multi-Level Airflow Systems: For multi-tiered growing systems, multi-level airflow becomes essential. Unlike traditional single-layer operations, multi-tiered systems have unique challenges, as each layer might have slightly different microclimates. The multi-level airflow system addresses these issues and ensures that each tier gets adequate air movement. Design and install these systems to ensure every plant receives a uniform air supply. Additionally, these systems help prevent diseases and pest infestations specific to each level. By effectively understanding and implementing these systems, growers can expect crop quality, yield, and overall plant health improvements.

7. Automate for Consistency

Automation in a CEA facility can encompass a multitude of systems and processes. Consistent automation could range from simple temperature and humidity controls to complex nutrient dosing, CO2 enrichment, and integrated pest management systems. By automating these processes, growers can ensure that plants receive the exact amount of water, light, nutrients, and other necessities at the right time. Such precision maximizes crop yield and quality and minimizes resource waste. When external conditions, such as temperature or sunlight, fluctuate, automation systems can adjust internal conditions to maintain the desired environment, ensuring that plants remain unaffected.

In addition to enhancing crop growth, automating processes can lead to operational efficiencies and labor savings. Modern automated systems often come equipped with data analytics capabilities. Allowing growers to monitor trends, make predictions, and refine their cultivation strategies to minimize utility and nutrient use while adjusting for optimal conditions. Having access to this information not only reduces costs but also lessens the environmental footprint of the facility.

8. Invest in Training and Continuous Learning

Setting up a CEA facility is a multifaceted undertaking that demands an in-depth understanding of various interdisciplinary domains. It amalgamates knowledge from botany, engineering, data science, and even business. As such, training and continuous learning become crucial components for the success of any CEA initiative.

Initial Training

When first embarking on a CEA venture, the team should undergo intensive training on the fundamentals of the system. This type of training could range from understanding plant physiology and its specific requirements for optimal growth to mastering the intricacies of the CEA technologies. Light intensity, nutrient mix, temperature, and humidity must be controlled and optimized. Mistakes in managing these variables can result in crop failure or suboptimal yields, making training a critical investment for long-term viability.

This training isn’t just limited to technicians or the individuals directly handling the crops. Stakeholders at all levels, from managerial to marketing, should fundamentally understand the operations. This training ensures everyone is aligned, leading to efficient decision-making and problem-solving.

Continuous Learning

As with any technology-driven industry, the world of CEA is constantly evolving. New research provides insights into better crop management practices. Technological advancements introduce tools and systems to optimize plant growth and reduce operational costs. Given this rapidly changing landscape, continuous learning is not just beneficial; it’s imperative.

Team members should regularly attend workshops, seminars, and courses. Many academic and research institutions offer specialized programs focused on CEA. Online platforms have become treasure troves of knowledge, with webinars, courses, and forums dedicated to CEA best practices. Leveraging these resources can provide a competitive edge.

Collaborative Learning and Networking

CEA facilities can benefit immensely from networking with similar operations elsewhere. Collaborative learning opportunities can be invaluable, where facilities share successes, challenges, and learnings. Collaborative efforts could lead to shared research projects, the pooling of resources for better training tools, or even joint ventures in exploring new markets or crop possibilities. Leverage the collective knowledge of the CEA community to overcome individual challenges and push the envelope on what’s achievable in controlled environment agriculture.

9. Implementing IPM Program

Implementing Integrated Pest Management (IPM) programs in Controlled Environment Agriculture facilities is essential for ensuring crop health, optimizing yields, and overall success. Due to the controlled nature of these environments, there’s an opportunity to adopt a comprehensive and proactive approach to pest management. IPM focuses on a holistic approach, combining various strategies to manage pests and pathogens rather than relying solely on chemical pesticides. In a CEA facility, it starts with preventing pest entry. Pests mainly gain access via new plants, materials, or humans. Regularly inspecting and quarantining new plants, ensuring the facility is airtight, and having proper hygiene, cleaning, and sanitation protocols can help prevent pest entry.

Continuous monitoring is crucial for an effective IPM strategy in a CEA setup. Use yellow or blue sticky traps to monitor flying insects’ presence and population levels. Once pests are detected, it’s vital to identify them accurately. Not all insects or microorganisms are harmful; some might even be beneficial. Accurate identification ensures that the response is appropriate and effective. Beneficial insects, like ladybugs, predatory mites, and parasitic wasps, can be introduced to manage pest populations. A controlled and sealed environment maximizes the efficacy of releasing these biocontrol agents.

In a CEA facility, growers have the advantage of adjusting environmental parameters, such as temperature and humidity, to unfavorable levels for pests. Physical controls, such as barriers, screens, or UV light traps, can be installed to prevent or reduce the entry and movement of pests. While the emphasis in IPM is to minimize chemical use, sometimes it becomes necessary, especially when pest populations reach threatening levels. In such cases, select pesticides wisely. Preferably, choose those that are least toxic, have minimal residual effect, and are safe for beneficial insects. Rotation of different modes of action can prevent resistance development in pest populations.

10. Continuous Evaluation and Adaption

CEA facilities and associated growing methodologies significantly advance modern agricultural practices, emphasizing precise control over environmental conditions to optimize plant growth and production. This technology-driven approach to farming can be applied in greenhouses, vertical farms, or other indoor facilities and hinges upon continuous evaluation, improvement, and adaptation to optimize crop outcomes. Essentially consistently monitoring and adjusting conditions in real-time to meet plants’ specific needs throughout their growth cycles.

Continuous evaluation in CEA is an ongoing process of collecting and analyzing data on various environmental parameters. By regularly tracking these variables, growers can identify patterns, anomalies, or inefficiencies that may impact plant health, growth rate, or yield. CEA operations often integrate many tools and systems to facilitate the perpetual cycle of monitoring and adjusting. Sensors continuously measure soil moisture content, ambient environmental conditions, and nutrient levels, feeding this data into centralized control systems. Automated irrigation systems can adjust water delivery based on real-time moisture data, ensuring plants receive optimal hydration with minimal waste.

Similarly, climate control systems can regulate temperature and humidity, ensuring they remain within desired ranges. Remote monitoring and cloud-based platforms have become increasingly prevalent in CEA, enabling growers to supervise and manage their facilities from anywhere in the world. Remote monitoring and cloud-based platforms facilitate quicker decision-making and allow for collaboration among experts in different geographical locations.

Conclusion

As our world continues to change, efficient, sustainable, and optimized agricultural production becomes imperative. By following the ten essential tips outlined in this blog, you’re ensuring a well-established foundation for your CEA facility, promising higher yields, optimal plant health, and a significant reduction in resource waste.

Setting The Stage – Key Differences between Single-Tiered HPS vs. Multi-tier LED Cultivation

Many new moving parts may not integrate when starting and operating a new multi-tiered cultivation facility. By pre-planning and focusing on KPIs, you can stay ahead of your competition by making data-driven decisions. First-time commercial growers should consider having support from an experienced team member or consultant with a proven track record in mobile vertical grow racks. Cultivators with a collaborative approach with teammates and consultants with divergent but complementary skill sets typically result in best-in-class operations. Be prepared to pivot, as the market is constantly shifting. A common concern from a single-tiered high-pressure sodium, HPS, cultivator thinking about going multi-tier is concerns about reaching quality and yield goals.

The main difference between the two is the amount of the anticipated yield. The best single-tier HPS cultivators receive between 90 and 120 grams per square foot, roughly 200 to 260 pounds per harvest. Our typical LED cultivators are between 65 and 80 grams or more per square foot, slightly less than single-tier, but the number of grams will be per tier. Combining those two tiers means we have 132-160 plus grams per square foot, equating to about 285 to 350 plus pounds per harvest. These numbers may not seem like too big of a difference, but when looking at the difference in revenue, three-tiered LED cultivators are getting 190 to 240 grams per square foot; this ends up being about 530 pounds in the same room as a single-tiered HPS cultivator who was peaking at 260 pounds.

Something we also see as a limiting factor to quality and yield that we typically see within multi-tier is the room design itself, specifically around the mechanical system or HVAC design, and poor airflow. If your grow uses HPS, you typically focus on climate and root zone strategies. Those strategies are not very easy to take and apply to LEDs. With LEDs, you will need to slightly change all of your growth parameters to account for a different lighting spectrum. With LEDs, you can push your plants harder with different growth parameters. You can now raise your room temperatures with LEDs to achieve the same leaf surface temperature and VPD.

Key Performance Indicators (KPI’s)

Key Performance Indicators, KPIs, are how cultivators gauge performance and improve operations each harvest. Using data-driven cultivation with your KPIs helps keep a lot of the guessing work out of growing and allows you to make quicker and more decisive decisions on what is occurring in your garden. There are many KPIs and cultivation metrics to follow, but three main components can typically have the most significant impact on your business. The three components are yield returns, turns or harvests per year, and labor metrics.

1. Yield Returns

Historically when referring to yields we were referring to pounds of sellable product per light. Now, a universal metric to discuss yield is in grams of sellable product per square foot of canopy (or grams per square foot).

Those who have mastered the art of efficient room designs are consistently achieving remarkable yields of 80 grams per square foot in every cultivation cycle. It’s important to note that the key factor separating growers in the lower yield range is the need for mechanical system design, HVAC, and dehumidification improvements. By addressing these crucial aspects, growers can unlock their true potential and reach new levels of success.

2. Turns or Harvests Per Year

We encourage cultivators to have minimal downtime in between harvests. Ideally, this means a next-day room reset after you have harvested your plants – harvesting all of the plants in one day or shift in that flowering room or zone, cleaning and sanitizing that room ideally, same day or the very first thing you do the next morning. Cultivars could even have an evening shift in between if that’s an option, then you’re resetting and repopulating that flower room the very next day.

Cultivators should have minimal downtime between harvests because when you have nine-week flowering cultivars, that will equal 5.8 harvests per year. Each day that you’re not flowering has a significant ramification in potential revenue loss. For example, a 10,000-square-foot flowering canopy estimated at $1,000 per pound would equate to $6.3 million a year. If you take a week for turnaround time between rooms, even five days, that will end up being 5.2 harvests per year, coming out to be $5.7 million yearly.

3. Labor Metrics

Labor is hands down an operator’s most significant expense and can be the most difficult to manage. Labor contributes to roughly 30 to 40% of the cost of production. There has been a shift in tracking labor from a KPI standpoint. We would typically see how many growers there are per light.

A standard number would most likely be about one grower per 50 lights. We look at it in terms of employees per square foot of flowering canopy. Common industry practice is one cultivation employee per 800 to 1200 square feet flowering canopy.

Production Phases

Mother Room 

One of the most significant shifts we’ve seen in mother plant production is moving away from single-tier mother plants to a multi-tier mother plant structure. Instead of growing large mother plants, growers utilize small to medium-sized plants to stagger production. The benefit of working with small to medium-sized mother plants is that you can maintain the mother plants’ health easier and receive more uniform cuttings. All the different uniform cuttings from the side and inside of the mother plants have different metabolism and strength toward lighting.

Production Schedule for Mother Plants:

Typically, you see a production schedule for a grow operation, but rarely do you hear of a mother production schedule. The plants you choose as your mother plants should not be the leftover or aftermath of your veg batch moving into flower; they should be the healthiest of all the plants possible because that is the foundation for the future of all your batches. One trend gaining popularity is a clone-to-kill model or a cut-to-kill model. The advantage of a clone-to-kill or cut-to-kill model is you can only take cuttings off the plant once, and then you destroy that mother plant. These models give you some of the healthiest clones, but the downside is that the plants themselves take up valuable space, so you must create square footage when planning. The benefit of a multi-tiered environment for your mother plants is you can most likely shrink your mother room and have more mother production. When you shrink your mother room, you free up critical floor space for other parts of your operation.

Vegetative Room

In the vegetative phase, this sets the pace for your production cycle, determining how your plants will perform and flower. In this phase, uniformity and consistency batch to batch is critical. Vegetative strategies and lengths vary for every facility based on pot size, plant counts, targeted finished plant height, or tier heights. If you’re growing a lot of new genetics, we recommend measuring the internodal length every few days to track the growth rate and then begin grouping similar cultivars. Depending on how much each cultivar tends to stretch and the height of your growth tiers and flower, you can then vary your veg time from three days up to two or three weeks to get your desired finished plant height. The more dialed in your climate and root zone parameters are in your veg room, the faster your plants will root and grow more shoots, reducing your total veg time and allowing you to get more terms per year out of your cannabis facilities.

Plant Stress

All canopy management or plant training techniques have a cost regarding plant stress, which can add up if you must be more careful and timely in your plant process flow. Compounding stress events can result from multiple stress events all at once. For example, transplanting the plant into a new substrate, skirt or trimming up the bottoms of the plant, topping the plant, adjusting growth parameters like lighting, intensity, what type of lighting, the environment can be different, and humidity as they transition from bench to flower.

Flower Room

When operating a multi-tier flower room, transitioning the plants to flower and timing the stretch is crucial. Before moving plants from the veg room into the flower room, it’s best to preset the flower room’s climate to match the VPD conditions in your veg room. Preseting the room will help limit the stress on the plants during the transition. Once your plants have transitioned into flower, you can expect rapid growth over the first two to three weeks, with plants tripling or quadrupling in size. This rapid growth is the stretch phase of the flower cycle. The goal is to have the plants finish about six to twelve inches away from the lights at harvest, depending on your fixtures.

It’s best to start pinching the taller nodes and weaving branches through the canopy trellis right after transplant to get everything uniform in height, then continue pinching, bending, and trellising throughout the stretch to help with the stretching phase. Your defoliation strategy is also essential and used throughout flower defoliation. Plucking or removing leaves from the canopy to thin it out will help with humidity and airflow issues, along with reducing the number of leaves that have become sinks for valuable plant resources.

Harvesting Strategy

Harvesting is always an exciting time in the cultivation process, but it can be unorganized if not thought through and having a plan set in place. It is always a good practice to do a walkthrough of your flower room one to two days before with whoever is managing that flower room and then to meet with whoever’s working that harvest to have a plan moving forward over the next couple of days to streamline the harvesting.

One technique many people have found helpful in the multi-tier environment to make harvest day and cleanup easier is the dried-down or die-on-the-vine strategy for the last 24 to 48 hours. To utilize this strategy, dimming your lights will lower the signaling senescence and reduce all irrigation. This strategy leverages the transpiration process to dry your plants to get a jumpstart on the drying process before you move them into a dry room. The dried-down or a die-on-the-vine strategy can help dry rooms with undersized humidification capacity. By leveraging transpiration, there is less wet weight to move off the upper and bottom tiers on harvest dates. This strategy can mean the difference in a large flower room of a thousand total pounds you must move in a day, whether that is your substrate weight or the actual biomass itself.

Utilizing Pipp Horticulture’s modular drying carts to help wheel into the flower room to collect the plants for harvest will help minimize plant damage. You can wheel the plants into the dry room, and cultivators can dry them directly on the carts or transition them to drying rack hangers and a whole plant hang technique. It’s essential to wait until all plants are out of the room before cleaning and sanitizing. Handling and moving opened-up substrates, like cocoa, can add particulate fungi and bacteria to the air, contributing to high microbial testing of unfinished flower.

Size the room for your facility layout and dry rooms so that you can harvest a whole room in a single shift, ensuring the entire harvest will fit within a single dry room. If you cannot hold a single crop in a single dry room or do it within a single day, it’s better to have two smaller dry rooms to avoid the issue of plants drying at different rates at different speeds.

Harvesting & Drying Checklist: 10 Things to Know

Harvesting & Drying Checklist: 10 Things to Know

Drying Racks

Work Smarter, Not Harder!

In a vertical, multi-tier farm, efficient and effective harvesting and drying practices are essential for maximizing productivity and maintaining the quality of cannabis crops. This blog post will explore some best practices that can be implemented to optimize these processes and ensure successful outcomes in a vertical farming environment.

1. Prune Excessive Foliage

During the last week of the flowering stage, remove the majority of fan leaves and excess foliage while leaving the bud sites undisturbed. By doing this before harvest day, you minimize labor tasks and make the process more manageable. Additionally, it promotes better airflow and a more consistent moisture removal rate throughout the drying room.

2. Pre-Harvest Preparations

One harvest method many growers have found useful is to dim the lights and cease irrigation events approximately 24-36 hours prior to cutting the plants down. By leveraging transpiration during this period, growers can jumpstart the drying process and reduce the load on the HVAC system in the dry room during the initial stages of drying. This method also reduces the overall wet weight of the harvest, including the plant and its substrate, resulting in cost savings and a faster harvest process (i.e. less physical weight for your staff to move from the upper tiers).

3. Minimizing Touches & Transfers

Every touch and transfer increases the risk of product damage, degradation, and contamination. Minimizing unnecessary handling and movement of plants is essential. Aim to complete the harvest and transfer of a single crop into a designated drying room within a day to maximize efficiency and preserve product quality.

4. Utilize Modular Dry Carts

Invest in modular dry carts that facilitate the transfer of plants from the flowering area to the dry room. These carts simplify the movement process, minimize plant damage, and maintain organization within the facility.

5. Choosing the Right Load-In Strategy

Evaluate the benefits of both single load-in and continual load-in strategies. While a single load-in approach (one harvest batch into a single drying room) provides better control over the drying environment and consistency, continual load-in strategies (multiple harvest batches into the same drying room) can support continuous production. A single load-in approach is preferable but choose the strategy that aligns best with your facility’s goals and available resources.

6. Whole Plant vs. Hook n’ Hang

Regardless of the drying method chosen—whole plant or “hook-and-hang”—maintaining consistent plant spacing is vital for even drying. Initially, the drying space may appear crowded, but as moisture content decreases, sufficient spacing is created, allowing for efficient drying and airflow. Whole plant hanging is the preferred method by most growers as it tends to result in a higher quality product, reduced labor tasks on harvest day, and simplifies track-and-trace compliance duties.

7. Maintaining a Controlled Drying Environment

Invest in a properly sized HVAC system with sufficient latent load sizing to remove moisture effectively. The drying rate is influenced by factors such as the total wet weight of the harvest, room temperature, dehumidification capacity, airflow, and time. Increase room temperatures slightly (HVAC systems and dehumidifiers remove more moisture at higher temperatures) if the drying rate is too slow but be cautious to avoid excessive heat that may lead to terpene loss. To preserve product integrity, keep the dry room door closed and lights off as much as possible. Minimize unnecessary entries into the room, allowing for a consistent and undisturbed drying environment.

8. Moisture Content & Water Activity

Tracking moisture content (MC%) and water activity (Aw) levels is a great way to standardize your drying process, reduce your risk of product loss, and maximize your revenue. In the early stages of the drying process, the goal is to get your crop’s water activity below 0.65 to reduce the risk of pathogen proliferation and product loss. Use these readings to fine-tune and optimize your HVAC setpoints, either increasing or decreasing your drying rate by modulating temperature.

9. Achieving the Desired Moisture Content

Target a moisture content between 10-14% for optimal product quality and smoking experience. This range ensures proper drying while preserving terpene profiles and cannabinoid potency. It is a delicate balance; higher moisture contents increase the total sellable weight of your harvest while slightly lower moisture contents increase the total cannabinoid potency on your lab results (less water weight per gram).

10. Minimize the Mess

Harvesting and drying cannabis can be a messy process, but taking certain precautions can help minimize the mess and maintain cleanliness within your cultivation facility. For example, when the drying process is complete, it is best to “buck” or remove buds from stems directly in the dry room. By doing so, you confine the mess to a room that is already in need of cleaning, rather than creating a mess in another clean area of the facility. This approach simplifies cleanup and reduces the risk of cross-contamination between different cultivation spaces. Educate your staff on the importance of maintaining cleanliness during the drying process. Provide training on proper handling techniques, emphasizing the need to work carefully and avoid unnecessary spills or messes. Encourage team members to clean up any spills promptly and maintain a tidy workspace throughout the drying process.
