Depending on the size of the room I think just a small ac would bring your temperature down to the 60s and dry the air enough. As long as there’s no windows you wouldn’t even need a tent. Then just a small fan
My drying tent is pretty simple, just a tent and a AC Infinity T6 exhaust fan and one circulation fan (bottom of tent, always on for air circulation). I set the T6 to run exhaust when RH in the tent goes over 60, it runs constantly for first couple days and then cycles on/off as needed until the buds are at the desired level of dry.
Only issue I see with it being in your grow room is the temps, cold is better than warm, I’m usually at 65-68F and 60RH for drying.
Hey! A humble request for a newbie who is currently growing and looking to harvest in January. Can you please post a picture of your dry tent setup? Thank you @Hellraiser ! I love the movies by the way! Especially the original !
