    I have a 30 cubic foot grow box that I am trying to determine a ventilation scheme for. I already have 4 inch duct work and the materials to make a carbon filter. I was wondering what to use as far as fans are concerned. I was thinking about using a computer fan in line with the duct work, but was uncertain about how to power it. Any suggestions?

    best bet get a 4in inline fan

    Agreed^^^^ 4" inline 160-170cfm should suffice. I don't trust computer fans.
