If you’re new to growing cannabis, you’re probably figuring out a lot of things as you go along. When those big buds show up on your plant, you probably can’t wait to get a taste of what you’ve worked so hard to create. There’s only one problem. Name a single time you’ve ever smoked wet pot.
Growing your cannabis is only half the project. The other half is finishing your cannabis. Using it is your ultimate reward. Drying cannabis is the first step in finishing it. The process of cannabis from seed to bowl takes a while, but it’s well worth the effort.
Why does cannabis need to be dried?
Even when the flowers have fully formed on your cannabis plant, they aren’t quite weed yet. Cannabinoids continue to transform after the buds have been harvested. The buds on your plant are packed with THCA, but not a lot of THC. If you were to smoke them green and fresh, nothing would happen.
THCA transforms into THC after your plant dries and cures. It needs to undergo those final processes before it’s ready to use. As tempting as fresh-picked pot sounds, it’s probably not what you actually want. You have a little more work to do if you want to enjoy your weed in its prime. You worked hard to grow it, and you deserve to use it when it’s at its best.
How to dry cannabis
If you came into growing cannabis from a gardening background, you’ve probably worked with kitchen herbs. Basil, oregano, and rosemary all need to be harvested and dried for storage. Drying the herbs preserves them and adds to the complexity of their flavors. If you’ve ever tried and failed, you know how heartbreaking it is to wreck a whole crop of everything you needed to make marinara sauce. Cannabis is no different.
You can dry your cannabis by removing whole branches or by removing just the buds. It’s simpler to remove just the buds, but it can be harder to tell when they’ve fully dried. When you remove the whole branch, it’s usually easier to tell when your cannabis is completely dry.
For whole branches, you can hang them from the ceiling. You can remove the leaves and manicure your buds before you dry them. For just the flowers, manicure them and place them on a drying rack.
The room you dry your cannabis in needs to be dark. It has to have sufficient air circulation and a maintained humidity level of about 50%. A dehumidifier can help you with the humidity level, and a tool called a hygrometer can measure the humidity in real-time. Accurate data will help you make adjustments to the humidity, which will usually involve adjusting the dehumidifier up or down.
The air should be moving around as much as possible. An air conditioner or an industrial fan can accomplish this part, but you want to make sure that it doesn’t get the room too cold. About 70 degrees is perfect. It won’t keep the weed chilly enough to preserve it without drying it, and it won’t be hot enough to cause the compounds to break down prematurely.
Cannabis can take up to two weeks to completely dry under ideal conditions. Cannabis on the branch will take longer to dry, but it’s also easier to check its moisture levels. If you can bend and snap the branch like a twig, it means that most of the moisture has left the plant.
The buds should shrink in size as their water content diminishes, and it’s not unusual for the outside to start to feel a little crunchy. When you have snapping branches and flowers with a crisp exterior, your weed is probably dry enough.
Making sure your weed is adequately dry before you cure it is extremely important. If you try to cure weed that’s still too wet, trapped moisture can make your flowers rot. There’s no coming back from that. On the other hand, you don’t want your weed to be too dry before you cure it, because it will shrivel away to nothing and degrade the THC to CBN, a non-intoxicating cannabinoid. You need to find the sweet spot.
You’ll have a few opportunities to check the dryness during the early stages of the curing process. Catching the signs early on can help you salvage your weed. If humidity levels aren’t looking right, place it back in your drying space for a day and try again.
