Thanks , yeah I use 3 computer fans one is a cpu fan it's the fastest, I use that one and another one to suck the air out. I have one fan at the bottom to blow air in, I have been using it to blow on the plants but I'm letting them rest. It gets super hot if I turn a fan off like in the 90's. With all the fans the temp is usually 80f I have a thermometer in there.
