Hi there, I've set up a budbox and the temps are getting a bit too high so I think the best way to go would be to get a cool tube. Recently I bought a 4 inch fan/filter but now that I'm in the market for a cool tube, they all seem to be 5 or 6 inches! Would it be ok to just use my 4 inch fan with this cool tube, I could duct-tape my existing ducting on there somehow: http://www.basementlighting.com/Merc...age=1/PROD/RE6
I know there are guides and I could make my own but I'm useless at all that stuff. Anyway, any thoughts?
