I'm in your boat, I only have a wall between other mates so I must keep it to a minimum, I'm just glad you can't hear the ballast from my hps, but now I must think of a pretty slick way to get the ventilation going without making noise.

I was actually planning on drilling through the wall, and housing the fan and scrubber *outside* the closet inside a little speaker box, and then running tubing back through the wall into the closet right up to the light to remove the heat. Hope something like that will be possible though.

Edit: Isn't there types of sound proof dry wall you can buy?
