Inline fans

Is a 6 inch 440ccm inline fan too much for my 3x3x7 tent? or will it work fine

anyone??

Should be fine. Depends on your setup and how many bends etc tho

Get a variarc transformer (speed controller) to dial in your fan. a bigger fan is never a bad thing, room to expand!

I ran a variable speed controller in my 3x3 with a 6 inch fan and it worked great. All you need is one of these.

It will work fine. I crammed a 6" scrubber into a 2x2x4 and have my fan on the outside of the tent. I run it on 2/3 - 3/4 speed most of the time.
