Yes, it really does help. Unfortunately the walls are up and I really am left to go down the road I am on as far as space goes.

Here is another question I have. I am keeping the room sealed to be able to keep the Co2 as close to ideal as possible. I was wondering if people ever did this. So I have seen the HPS fixtures that have both an inlet and exit for like 6" duct work. Does anyone have a sealed room that has a close loop system just to vent the heat from the fixtures. I know I did not describe that clearly. What I mean is they have and inlet into the sealed room that is connected to duck work that goes from one fixture to another, then to a vortex, then out of the room. The reason I was considering this is to vent a majority of the HiD heat out of the space without sucking atmosphere out of the room. Is it possible to seal the duck work well enough that is would not pull air from the room.

Here are a couple pics, like I said walls are up for the most part.
