I have one more thing to finish my setup. Lots of info here at GC but kinda need up to date suggestions Here is the setup so far 4 x 4 x6.5 Tent (Virtual Sun) 400 Watt HPS/MH With non cooled reflector hood saw these two combos but have no idea if there are any good. Amazon: Amazon.com: New Hydropronic 6" Inline Fan With Carbon Filter Combo Odor Control Air Quiet: Patio, Lawn & Garden Ebay: 6" Inline Fan 6" x 25' Ducting and 6" x 24" Carbon Filter Package | eBay I like the price range and free shipping. Does any one have any experience with these or maybe a few other suggestions. I Will be purchasing a setup come Feb 1st 2013. Budget is $175.00 Thanks MoonRocky
Those combos are great. Just follow the right setup procedure for max cooling. If I was you I would spring for a nice fan to point at the fixture / top of plants to help cool. But you should be fine with a 4x4 with 400w if you have proper exhaust.
