Today I got something that I have been wanting for a couple of years now. A co2 generator and the various other stuff you need with it. Yippie! All Green Air brand, all from a hydro store. (I know, I'm crazy.) My wife isn't thrilled, but now I get to see if the claims of 20 to 40 percent increase in yeild are true, along with the claims of earlier bloom time. I'm not looking forward to the work involved in tearing apart my grow room and rebuilding it, but I am looking forward to finally getting this done.

I can't seem to find any information on the best place to mount the generator. According to the directions it doesn't really matter. It comes with a chain and hardware to mount from the ceiling, on the wall, or free standing. The Green Air web site doesn't address this, except to repeat the directions. I know that co2 is heavier than air, so I guess this means that I want to mount it above the plants, and not free standing on the surface under them. Do ya'll concure? And how high above the plants? Close to them, or way up by the ceiling. Calculations indicate leaving the generator on for 3 minutes will deliver 2000 ppm.

I don't know if this matters much, but the co2 is going in my flower section, which is about 3x3x9 feet, with the surface of the growing medium about 2 feet from the floor.

Any input would be great. I searched here and other places.

Next step: automatic dosers, then I'm pretty much done, I hope. Or does anyone ever really get done building their set up?
