How to Properly Dry Your Cannabis

Low and slow: your guide to cannabis drying techniques

Have some patience. There are many different variables to consider when drying cannabis, but the most important tool you can possess when learning how to to dry marijuana is patience. In his aptly named blog, “The Guru of Ganja,” Ed Rosenthal asserts, “for buds to be proud of, think ‘low and slow.’ Drying and curing flowers takes time and patience, but the finished buds are worth the wait.” Now that you are armed with unwavering patience to develop the flavors and aromas while removing moisture for the proper dry and cure, let’s look toward the elements need

How to Properly Dry Your Cannabis

Keeping a Low-Temperature Environment is Key in the Cannabis Drying Process

We now know “slow” refers to the amount of patience cultivators must have during the drying process. So, what does Ed Rosenthal mean when he says “low”? Low refers to temperature. The biggest predator of terpenes and cannabinoids are the elements of nature, evaporation, humidity, and friction. Terpenes evaporate at different temperatures. Some evaporate at temperatures lower than room temperature. Our first recommendation is to turn the thermostat down to 60º F (15-16º C).

Cleanliness as a Constant in Post Harvest Production

  • Wear gloves when drying and trimming harvested cannabis. Encouraging cleanliness throughout your team and maintaining a clean environment and is paramount to preventing bacterial and fungal growth.
  • Use liners when collecting freshly harvested plant material. The more contaminants you introduce into the drying room, the more your cannabis will be compromised. Drying and trimming rooms can become dirty very quickly. Mold growth will contaminate and force you to destroy product. Using liners in your totes and drums will prevent cross-contamination when storing cannabis.
  • Implement cleaning procedures. Employers of large-scale grows should have cleaning of these post-harvest production areas in their Standard Operating Procedures. Farms concerned with getting products out the door, and less concerned with the quality of their products, have dirty, impatient drying rooms and employees. Remember, you are curating a medicine with very intentional purposes.

How to Prevent Rapid Drying

When considering the airflow in your drying room, practice patience. Focus on the air circulation of the room. Position fans to create an even airflow and distribution. Do NOT position a fan to blow directly on a plant or at a wall. Rapid drying will result in a severe drop in quality. Now, let’s learn how to dry cannabis flowers!

How to Properly Dry Your Cannabis

  1. Create an optimal environment in the room

Your plants should be in a cooled temperature room with clean, cool-mannered people prepared to handle the plants for further trimming. Therefore, the drying room should be a dark, cool room with temperatures of 60ºF and relative humidity levels of 55-60%. Higher temperatures and humidity will promote bacterial and fungal growth while lower temperatures won’t dry the cannabis fast enough, potentially harming your efforts when you begin burning your buds.

  1. Start trimming your plants prior to harvesting

Trimming starts before the cannabis plants are harvested. Before the end of the flowering period, you should prune to allow for optimal light distribution across your canopy.

Cut larger fan leaves.

After harvesting, cut out any of the large fan leaves that remain and hang the whole plants or large branches from a drying rack. Keeping most of the vegetation, smaller fan leaves and the sugar leaves, on the drying plant will allow for a long, slow dry because of all the extra water you’re leaving on the plant that is locked into the vegetation. Remember your mantra, “low and slow.”

Hang your plants properly.

When hanging your branches from the drying racks, make sure nugs are properly spread out and are not resting against each other to prevent mold growth. Cleanliness needs to be accounted for in every step of the drying process. Even plants can contaminate plants. Have employees check for quality and mold/mildew growth frequently when drying and curing cannabis.

Pro Tip: Use drying racks to hang cannabis instead of trays.

Trays are used after wet trimming. Wet trimming causes huge quality loss – the nugs will dry too quickly and lose terpenes. Trays limit the amount of exposed surface area and lead to an uneven dry. Trays are also more labor intensive, as the buds need to be turned constantly to prevent flattening one side.

Allow at least seven to ten days to dry.

Practice patience. You want to allow the plants at least a 7-10 day time frame to dry; some farms even allow for a 14-day dry. With a slower dry, the plant will retain a larger and wider terpene profile, preserving the fragrance and medicinal benefits of the whole plant that would be lost in a rushed dry.

Opt for dry trimming over wet trimming.

Once the cannabis is dry on the outside and the stems are starting to snap, it is time to trim. We recommend a dry trim rather than the wet trimming mentioned in other cannabis drying articles. Trim all remaining fan and sugar leaf off the buds. Save the sugar leaf to be processed into concentrates or infusions.

Now, your cannabis needs to be sweat.

The process of sweating cannabis is often overlooked and yet it is a crucial step in the drying and curing process. While the buds are dry on the outside, there is still condensed moisture in the core of the bud that needs to be sweat out. By allowing the moisture at the center to be drawn out and redistributed throughout the entire bud, you’ve taken an important step toward mold prevention and preserving those aromatic, flavorful terpenes.

Transition your nugs into the optimal cannabis climate.

How to Properly Dry Your Cannabis
