yep, I have 2 muffin fans-100 cfm at the bottom of the closet. 250cfm inline exhaust fan at the top. So a total of 3 fans but only 2 really deal with the heat, the other small fan just blows air over the plants so they grow strong. I had to make sure there was no air leaks or the fans wouldnt create any suction. peace ollie
