I'm getting MH lights (to add to my PCs), so I know I'm going to need to install some fans in my canopy. Does it work to simply install the fans hanging on the back (blowing out?), or do I need to cut holes in the sides and install them there? Do you generally blow air in or out?
 
Go the page two on this sectiion and a little ways down you will see a post i made about fans and mh. If you have any questions just let me know.
 
fans suck hot air out ! blowing air in can cause cool spots on the bulbs which can damage them i guess !
