My drying area is a partitioned off section of the room my tents are in. It's got a window in it. I just made a wall out of foam board. I've got everything in there I need to maintain the temperature and humidity. My question is do you think I need an exhaust fan circulating new air into that drying section of the room? And if yes, how would you do it? I could either pull air out of it and let it suck in its air from wherever it can pull it in from, or I could push fresh air from outside into it. Or I was wondering if maybe I don't need fresh air for the drying process if I would be good without an exhaust fan? Just some regular fans circulating the hair around the room. If it helps when I get home from work I could I post a video and some pictures of my setup. Thanks for the help guys.
