which is better to mount fans from each end of the canopy with one blowing air in and one blowing the air out, or mount them in the top of the canopy blowing downward. I have a 48x18x15" tall canopy. Ill be installing retro 2x250 MH and 2x110 VHO. If you have any pics or advice do's and dont's, all would be appreciated.

Is the canopy fully enclosed? Or is the back open? If the back is open, which most are, then you'd probably be best off by mounting one on each end and have them both blow in. If your canopy is fully enclosed then two blowing in and two sucking out would work. It also depends on the fans and how quiet you want them to be.
