you dont need that specific hood, just any aircooled hood, they are enclosed with glass, bulb inside and sealed so you can attatch a high velecoty fan via duct to suck or blow the hot air out without sucking air out of your room, this will seriously help with heat issues as 1000watters get crazy hot. i think your plan is good with 6 pots under 1000watt lamp, like i said before i choose to put 4 pots under each 600w. with my experience you would want to use no less than a 450cfm fan per 2000watts. thats the bare minimum/ i run 3 x 600;'s per 450cfm fan, and if i could do it again i would get my hoods to come with 8inch flanges and not 6inch, and i would get 8inch fans and ducting for better air flow thru the hoods. air cooled hoods will also allow you to use co2 down the road without sucking it all out
