Exhaust fan upgrade??

[godspeedsuckah]

I have a 1hp (180cfm) exhaust fan which I duct my 400w hps through. Tomorrow I am going to be picking up a 600w and would like to exhaust them together; should I upgrade my fan to keep temps in check, or is a 180cfm enough to handle a 600 and 400w? My closet is 2.5'w x 8'l and the temps are a comfy 72 currently.

No way. Upgrade.

This is the one i was looking at. would this be enough?

Srry was out. 265cfm. Sure. IMO, I would go with 6" CAP fan for same price.

Its 435cfm.... More is better. Gives you room to "grow" a bit too, if needed.

Thanks for the help. I will go with at least 435cfm.
