Exhaust Fans

[golfnrl]

Hooray! She said I could add another grow tent in the grow room!. So, I bought another Gorilla tent. 4 x 4 x 8 (ok, 7'11") . I'm looking at exhaust fans. My set up doesn't allow for venting outdoors so there won't be any long duct runs. Fan noise is the primary concern for me. I'm considering both 6" and 8" fans. I'm leaning more toward the 8" so that I can run it at a slower speed. Any favorites or recommendations? Lots of good options, me thinks.

An 8" fan is too much for a 4 x 4. I use variable 6" fans in 4 x 4s and I turn them all the way down, still getting more than enough negative pressure. An 8" fan turned down is enough for a 4 x 8.
