Well, I didn't get to flowering yet, but that filter looked man enough to handle the job. Input was 5 inches in diameter and filter itself was about 8 by 20 inches. And because it goes to chmney I am not worying about smell at al but it might be different case with you. But I think if you browse net, you can find all the info about the flow and how well it works which is what i did. Also I do have one more fan, just a small baby one (underneath microwave) blowing air in, but that one I don't use that often, because you can hear it and it drives me crazy. The one in chimney is much bigger but quiet. The small one I just turn on when I go to work just to make plants moving a bit to make them stronger. I would leave it on all the time if I knew it affects temperature but unfortunetly it doesn't.
hope it's any help to you...
and hope you have less yelow leaves than me...
cause it's a bloody science

I did the same thing as you. Cheap light first than cheap fan. Than I tossed away cheap light and bought more expensive one and at the end I had to buy proper fan. Should do that on beggining. See, if you dont have a space like me, or you. You have to keep air moving and eve the big fan, when you run ducting more than a few meters, or not in a straight run you can reduce flow quite rapidly. So if you can buy the biggest fucker you can accomodate and afford and your temp will be sorted. I should buy bigger one myself, but I allready spent enough and I am just on limit of temp and it seems to be ok regarding heat. Bloody nutes are doing my head now!

take that out of your chamber and that should help the temperature situation.

yes it is always best to have the ballast in a different room with separate airflow i actually drilled a hole in my ceiling and put it up in the addict. but my walls are sheet rock
