Go with the 250w and use a 5" fan and filter combo on a speed controller to run it slow during colder times and it can then be cranked up during summer.

your going to need a aircooled hood or cooltube i would think or your going to have way too much heat inside...maybe if you had a really good exhaust fan pulling the heat out of the top....

hopefully thats enough. my 240cfm 6 inch inline barely cools my 2x4x5 tent with a aircooled hood.

which only cost like 25 bucks on amazon btw. you can get cheap fans that work way better than most home made fan units like your talking about. believe me ive tried that lol

well lets just say my 2 x 4 tent will get up to 110-125F if my 400 watt is not properly air cooled.
your looking to be around 70-80F

A four-inch fan with enough cfm, like a CanFan, will do the trick. Computer fans are designed to work in a low-to no-load environment. You want an axial that can pullll ... and when you realize you need charcoal, it'll be something you're glad to have ... all jmo. cn
