Fantech makes great fans...
ask the guy at the store about them working well with speed controller..

ask about noise and vibration at lower speeds...

Your grow space is very small .... a 265 cfm fan will only need to come on for 10-20 seconds every 5-10 minutes... you could also hookl up a temperature sensitive swtich as opposed to a speed controller..

Then your fan will come on only when it gets hot in the grow chamber.

BREATHING is FUN
