Hi all, a friend of mine is doing a grow just now in the grow tent I gave him which measures 1mx1mx2m (DRstreet 100) and is vegging under a 250w metal halide and will be flowering under a 400w hps. I have loaned him an extractor fan (made for the bathroom, £10 on ebay) but we aren't sure if it is powerful enough, it moves 70m3/ per hour. Would this be powerful enough or should he invest in a more powerful fan? Intake is passive, and there is a 7" oscillating fan inside:stoned:
