So will it be enough to have this fan to fully ventilate 4x4 grow tent? http://www.ebay.co.uk/itm/4-Hydropon...EM&refid=store As I understood it can push air in & out, is that correct? Or only out? Thanks
I'm going to use 400w hps bulb btw.
QFT!!!!I personally recommend the Panasonic Whisperline series of fans... My box fan is several times louder than the Whisperline!
