I'm not an expert but there are two reasons, as I understand... one, plants contain photo-sensitive chemicals (chlorophyll, etc.) that you don't want reacting to light during the cure. The second, and probably the most important reason, is that THC will degrade with light expossure.why should it be dark when drying (hanging) buds does light affect it???
and what should temp be around in room?
thank you for replys
