You can expect to lose about 3/4 of the weight of freshly cut buds as the water dries out. Drying weed at the optimal humidity and temperature levels will ensure a slow dry. It is important to dry as slowly as possible, because if you dry too quickly the bud color, taste, and smell will be negatively affected and you risk over-drying your buds as well. You can easily maintain the proper humidity level in a grow tent or drying room using a humidity controller connected to your exhaust fan or dehumidifier. Since drying weed will give off moisture and raise the RH within a small tent, you can set the controller to turn on your exhaust at 55% and then turn off when the RH hits 45%. We use an Inkbird IHC-200 humidity controller (around $40 on Amazon) and it works great for drying weed plants. Never dry your cannabis plants in the microwave, food dehydrator, or an oven unless you really want to mess with the flavor, smell, appearance, and smoothness of the buds. Any method that dries too quickly will make your buds’ quality less than it could be with proper slow drying techniques at the best humidity and temperature levels. Excess heat will negative affect the terpine profile of your buds, which in turn will affect their taste and smell. Exact amount of time it takes to dry marijuana plants depends a lot about the environment where you dry them.
Drying in high temperatures will cause drying to occur quickly. Low humidity levels will also dry your buds out quickly. It usually takes between 5 to 10 days to dry out marijuana to the proper level.
