I have been having problems with powder mildew. I wanted to increase my ventilation so I purchased an 8" hyper fan (710 cfm). I'll post a picture of my current setup, I haven't installed the new fan, I was going to switch it with one of the other fans but I can't decide where to put it. But now that I research and do.some calculations I feel I may have too much air circulation? Is that possible? Sent from my SM-N920V using Tapatalk My room is 4x8x7. It's a tent.
