Yes you want that ideally.

However, as much focus as you place on exhaust, you need to place on the air intake temps.

So, I wouldn't put up a 1K watt bulb in a garage or attic.

But if its indoors and the incoming air is say 75 or lower, by all means its fine.

As for your exhaust, always go on the safe side...get the bigger unit 465CFM...you can always also buy a "Variable Speed Controller" to hook up and tone down the draft if needed.
HARDDON Reviewed by HARDDON on . 1000watt hortilux in a c-22 Is it possible? I'm looking at building a new cab soon and I was thinking of this combo. -C-22 -1000watt hortilux in a vented hood connected to a carbon scrubber -265cfm dayton or 465 not sure is the 265 is enough. -Mylar -Probably at least one active intake but more than likely 2 With a set-up like that or similar would it be possible or would it be too much to try and keep the temps down even with the hood? Any input would be greatly appreciated! Rating: 5
