i would stongly disagree with the above statement on the sun being better then a 1000's wttr, as i have read the sun has 10,000 lumens per squarefoot, which up to you and how u want to destibute your hid's, so small grow with a 400wtter will do the same in a 4x4 space as the sun. Just a neat fact.

Yeah man get a cool tube and a blower and ur set. a blower alone could work depending on you space. i dont use vented hoods and my heat has always been ok even in a 4x2 space with 6 foot head room and i didnt exactly duct propperlly
