Introduction

  • Hosted by Michael Williamson and Anders Peterson from Pipp Horticulture.
  • Episode focuses on curing cannabis, part of a three-part series on harvesting, drying, and curing.
  • Discussion blends traditional methods, scientific advancements, and industry best practices.

Understanding Curing & Its Importance

  • Drying vs. Curing: Drying is a rapid moisture reduction, while curing homogenizes moisture content.
  • Curing enhances the terpene profile, reducing the “grassy” chlorophyll aroma over time.
  • Enzymatic activity and degradation of compounds like chlorophyll play a key role in quality.
  • Environmental factors like temperature, humidity, and light exposure impact the curing process.

Different Curing Approaches

  • Some commercial growers treat the entire drying room as a curing space.
  • Traditional methods include curing in bags, jars, totes, or turkey bags.
  • Burping (controlled opening of storage containers) is used to release excess moisture.
  • New technology is emerging, such as auto-burp systems and sensor-based monitoring.

Science & Variables in the Curing Process

  • Ethylene gas plays a role in the ripening process (similar to bananas and tomatoes).
  • Vapor Pressure Deficit (VPD) impacts moisture release during curing.
  • Cannabinoid changes: Overexposure to oxygen converts THC to CBN, making cannabis more sedative.
  • Environmental consistency is critical – differences in humidity, temperature, and air circulation affect the final product.

Challenges & Best Practices in Curing

  • Different strains (cultivars) require different curing approaches.
  • Sorting buds by size and density helps create consistent drying and curing conditions.
  • Packaging matters – nitrogen purging was used in the past, but it sometimes reduced flavor quality.
  • Commercial growers need to maintain uniform environments in trim rooms to avoid unintended drying during processing.
  • Modified Atmospheric Packaging (MAP), commonly used in the food industry, could play a role in long-term cannabis storage.

Industry Insights & Future Research

  • Many growers still rely on experience ("feel") rather than scientific testing.
  • More research is needed on ethylene gas’s role in curing and optimal curing environments.
  • Tobacco and food drying industries offer some insights, but cannabis curing is unique.
  • Technology like Curepuck and sensor-based burping solutions could improve consistency.

Closing Thoughts

  • Curing is the key differentiator between good cannabis and high-quality cannabis.
  • The science behind curing is still evolving, and industry collaboration is needed to refine best practices.

Episode 39_Landing Page

Summary:

In this episode, the hosts dive deep into the intricacies of cannabis drying, sharing expert insights on best practices, airflow management, and the common pitfalls to avoid. They discuss the importance of controlling temperature, humidity, and airflow to ensure consistent, high-quality drying. Key topics include the pros and cons of different drying setups like racks vs. carts, how to avoid microclimates, and the importance of maintaining a controlled environment. The episode highlights the often-overlooked impact of drying on the final product and offers practical tips for improving the process, from designing the drying room to understanding moisture management.

Drying Room Basics:

  • The drying process is key to producing high-quality cannabis, and airflow is a critical factor.
  • A drying room setup typically involves multiple people, with one or two focused on managing the drying process.
  • Adjusting airflow is essential, especially during the "poofy" phase when the crop is wet and holding a lot of moisture.
  • Over-drying can happen if fans are not positioned properly. Airflow should not be directed directly at the crop but rather across the room to avoid excessive drying.

Fan and Airflow Management:

  • There’s debate about whether it’s better to push or pull air through a drying room.
  • The ideal airflow design often involves drawing air through the room, avoiding direct fan placement on the crop itself.
  • The design of a high-end drying room (e.g., Conviron Chambers) uses perforated walls to evenly pull air through the crop, enhancing consistency.

Carts vs. Racks:

  • Racks, when compared to carts, offer better airflow as there is more space between tiers to circulate air effectively.
  • The height of racks (12–18 inches between tiers) provides space for better airflow, especially around the thicker colas that retain more moisture.
  • Carts, on the other hand, do not allow for as much airflow between plants, which can lead to uneven drying.

Drying Room Design:

  • Proper drying room design should ensure minimal disruption to the drying process, such as ensuring fans are well-positioned and avoiding microclimates created by improper airflow.
  • Lights should be kept off and doors kept shut to maintain consistent conditions inside the drying room.
  • Sealing the room properly (including door sweeps and thresholds) helps maintain a stable environment.

Quality Control in Drying:

  • A consistent, controlled drying environment is crucial for preserving the terpenes and quality of cannabis.
  • Over-drying or improper drying can degrade the product and affect its final quality.
  • Taking the time to measure and map out temperature and relative humidity (RH) across different areas of the room can help optimize the drying process.

Curing and Final Product:

  • Drying and curing are interconnected, with the drying phase playing a major role in the final product’s quality.
  • The podcast hosts emphasize that drying should not be overlooked, as it has a big impact on the product's outcome.
  • They mention potential future research through the Cannabis Research Coalition to help improve drying techniques and share more data on the subject.

Closing Thoughts:

  • The podcast encourages listeners to experiment and find what works best for their setup but also emphasizes the importance of following key drying principles for the best results.
  • The hosts highlight that, while drying is a complex process with some subjective elements, good practices and attention to detail will lead to high-quality cannabis.
