That fan alone might be enough for ventilation...thats a big fan.

You gotta figure out the cubic volume (HxLxW) of your growroom and then check the CFM(cubic feet per minute) rating of the fan. You want a fan that can exchange your total volume in a certain amount of time.

Since im not really expert at this, im not sure how fast it has to be exchanged. Something like 5-10 minutes i believe.

Also, a fan like that is loud, might have to soundproof it.
