I have been wanting to set up two grow spaces but don't want to dish out much more cash. I came up with this way to ventilate two 3'x3'x5' tents, one which would hold my 250w and one that would hold ten 23w cfls, using my single 6" inline fan rated at 400 cfm and my one carbon filter. The filter has a capped end so I can't put it in the middle of a duct run. Instead I will build a small box that will hold the filter and the inline fan will pull through the filter and push through a short duct out the window. The box itself will have a 6" duct entrance. Here will be a 200cfm booster fan blowing into the box. The fan will be hooked to a y split. Each Y split will be connected to a duct that runs to each tent. The tents will have 10" passive intakes and small oscillating fans.

Which tent are you using? My 3x3 GL120 has 8 inch ducting sleves for intake. Either way with a 400cfm fan hooked up to 6 inch ducting, I think you would be fine running 8 inch intake. But that's just me
