In my 4' x 2' x 7' tall closet, (400w MH plus occational CFL suppliments) I use a 12" circulating fan, and it works fine. 600watters get pretty hot tho. I'd set her up, and see if the heat will be an issue before making any decisions. You'll have to see what the carbon scrubber requirements are for CFM, too.

Are you just exhausting out of the closet into the room, or are you planning on routing it outside? Are you running a batwing, or a hooded reflector with glass and an exhaust vent? Just curious because what you can do is determined by what you have, lol.
