Just bought a 1000watt hps

I was wondering what you guys think i shood do for cooling. i have an intake duct coming in from the outside air, and i was thinking i can put that directly to the hood and have the exhaust go outside the room into the attic

my question is, who much cfm of fan do i need for my 1000 watt hood? 250cfm just for the hood enough?

My 100 watters dont reall add to much heat to my rooms and I dont use glass or air cooled hoods or cool tubes.How big is the area I usually dont use smaller then 8x8x10 rooms without issues.

you mean 1000 watters right?

anyone have a ventilated 1000watt hood?

i have four air cooled 1000 watters, and i have two hurricane 630 cfm, one fan for for each two lights, that i exhaust in a notha room, but if i could do it again i would get the 8'', for better air flow, there like a 100$ more and it goes up to 650 cfm
