I have a 2'x4'x5' tent with a 6'' max pro and filter attached. However, I kinda got ahead of myself and cracked 4 different strains in it. Now I'm concerned that I might have to run it full blast to keep down the smell. Anyone know if I can just run it on low for smell control? I already built an mdf box around the fan and use a controller, but can still hear this thing running through the door. Thanks guys.
