No fans directly on your plants. You want air movement. Not direct air on them. It's all about indirect air movement. If you place a fan directly on them you will cause wind burn. It makes the plant transpire more quickly drying up the foliage. They don't like that. Nice tent dude. What strains ya running?I was wondering was this good positioning for the fan it’s a 3x5 this was the easiest spot to put it on also without pushing the tent pulls outward
