Set the room first
Prepare early
Test darkness, airflow, temperature, and humidity before harvest day, not after the plants are down
Drying space layout
Hang lines, net shelves, or shallow trays so every flower can touch moving air
Undisturbed zone
This is where finished buds rest until they are ready to jar, not a busy walkway
Shallow layers
Boxes and trays should be a thin layer so moisture can leave, not a packed heap
Air and moisture gear
Circulation fans
Keep air moving around the flowers, not blasting one cola for hours
Ventilation
Exchange moist room air for drier air as water leaves the plants
Dehumidifier
Pull water from the room when outdoor air is too wet to dry cannabis
Cool supply
Ventilation should bring in cool, dry air rather than a hot, wet draft
Targets that work
Cure band: Hold about 60 to 70 F (15 to 21 C) and near 50 percent humidity while cells still finish.
Dry band: At 50 percent humidity, most flowers take a week or two, depending on size.
Faster dry: Dropping humidity toward 40 to 20 percent speeds water loss once the cure phase is done.
Cool coil: An air conditioner set near 65 F (18 C) both cools the drying space and wrings water from the air.
If mold appears
Humidity cut
Drop the room to 40 percent humidity or lower right away
Warmth bump
Raising temperature toward 75 F (24 C) slows many molds and lets air hold more water
More air
Increase airflow and spacing so wet pockets cannot sit still
No sealed wet bags
Never park moist flowers in plastic while you wait for the room to catch up
