How do you guys keep a consistent temp when drying your flower? I have a portable A/C unit in a small bedroom, with a small exhaust fan blowing cool air into the tent. But the temp fluctuates up to 72° degrees sometimes. I have it on 66° with a small dehumidifier in the tent. I'm afraid the portable unit won't make it through the two week drying period, working at that temp 24/7.
