ok im growing in a small stealth cab and its like 2x2x2ft. I just installed my home made carbon filter and a new 4.5 in. computer fan that moves a lot of air. It worked all good but the catch was I could now only have 2 26w cfls and if the cab was closed all day the temp would climb up to 90f but Ive been keeping it at around 77-85. I really want more light but I caint deal with all the heat it puts out. So im thinking about getting this 90w tri-ban ufo and I was wondering if it puts out as much heat or less then two 26w cfls?(this might only be able to be answerd by a 90w ufo owner) Im trying to get the maximum amount of light and yeild without getting a nosiy in-line, I already baught one and it was to loud and it would like take up 1/3 of my grow area so I returned it.
