I'm going to purchase a vortex. I have 208 cubic feet (total room that is in shape of L). I'm going to make a scrubber (bodom's) and I am venting into the attic which will be only a couple feet away from the light. I will be running 800w in one reflector. Will the 172CFM 4 inch vortex be enough, or should I go to the 6 inch 440? The light has a 4inch hole, but if I am correct, I will have to use a reducer in any case since I believe the proper set up is light, scrubber (which uses reducer, correct?), fan, out into the attic.....if that makes sense. I have passive intake. I'm thinking about drilling a hole in the wall and moving the ballast outside the room and allowing more intake less heat...necessary?

Let me know, I'm itching to get the fan, lol.

Thanks, :jointsmile: Bree
