    could u use one fan for a grow box if u put one fan in the box sucking the air out. if u still have the fan hole for the fan to take air in it should suck in automatically if u are taking air out shouldnt it?

    does ne on think this would work?

    yes it works. its called pasave air intake and it works very well!

    a passive intake also helps make a vacuum to help seal the doors;)

    we tried this but the temp was too high! having an intake and exhaust fan reduced temp by about 10*c
