Dry Tent Temp 67F, Options?

67.3 f is not bad for drying if anything its almost perfect. I dry anywhere from 18-25c or 64-77f, my ideal would be 15c but I never get that unless I open the doors in the winter so 18c is my new go to. I try and keep RH around 60% with some small airflow happening. If no airflow then aim for RH to be 55%, no mater the temp RH should not be below 40 or above 60. someplace in between. To low = drys to fast, to high = potential for bud rot. The RH of the air its pulling into the tent / dry room should be lower then the RH of the tents ambient air. I set my tent up to dry the weed with pools of water on the bottom and program the smart exhaust to turn on low when RH hits 60%+ then by the time it auto shuts off the RH is back down to 40-50 and it does this for about a week or two. I only rely on my central AC and however cold the apartment is, I don't cool the dry room specifically and my shit turn out nice and dank. Good Luck!
