Good question. I will be harvesting soon and am now going to be drying in a new room that is an addition and doesn't have central temp controls. I will be around the same temps. I am also curious! I always was under the assumption you want a cool,dark place...and heard of people putting fresh harvest in the fridge to bring out more trichs. So maybe colder is better. IDK I'm half asleep and baked but hope to see a definitive answer.
