THANKS ALOT BUDDY , That really helped . Its says I need a 210CFM to exchange air completely every 5 mins but I got a good deal on a 424cfm so that means Ill be exchanging air every 2min and 30secs , that should help with keeping that hot air out the room/reflector

i got the same exhaust fan except it's 4'' from htg supply. works excellent. you can also get hoods with glass under them and the exhaust hooks right up to one side and sucks out most of the hot air before it even gets inside the room/tent. the hood i got is called the euro reflector http://www.htgsupply.com/viewproduct.asp?productID=49541
