Greenhouse Fans

[CariC]

Hi everyone. I'm in the process of setting up my first greenhouse. It's an 8.5 x 8.5 with one roof vent and one side louvre. Both open automatically when the temperature rises.

I'm currently looking into circulation fans, and I was wondering if anyone could recommend some good ones. What should I look for in a fan? How many do I need and what's a good size? Any help would be greatly appreciated!

I consider the Schaefer circulation fans to be the best quality (but with a corresponding price). A single 8" fan should be enough for your greenhouse but I would suggest a 12" Schaefer fan since it can be used with a speed controller. There are much less expensive speed controllers than the ones shown here.
