I am getting ready to build my own carbon filter and I am looking into a 6" fan for my closet grow. I only have 2 plants but i'd rather be safe then sorry. Plus if this first grow goes well I will more than likely try 3 or 4 plants next grow because I do have the room. My closet has a 1ft x 1ft section of sheetrock removed near the floor for passive intake. The room its self is 43"W 26"D 64"H. So can anyone recommend a 6" fan I can use to attach to a carbon filter? I was looking at this but i am not sure about it.
