They they are with all the other box fans. Its black and yellow and yes they move a heck of a lot of air fast! :thumbsup:
chongman420 Reviewed by chongman420 on . Exhaust fan? Is there any cheaper way to find a 300 CFM fan than paying $150-$200? Would taking apart an Oscilatting fan (so that it is just the cage, motor and fan blades) and installing it into the sealed growbox work? Or buying a wall mount fan and putting it in the box work?
