The small co2 generator I'm looking at puts out 3 cubic feet per hour and runs 100 degrees cooler that others. It doesn't say what degrees it runs but with A/C and a timer I can figure it out for the size of the room. A meter would help a hole lot in the beginning just to tune in. you can put 3 more burners in at 30 bucks a piece to bring it up 12 cubic feet per hour for bigger rooms.

We are trying a sealed room now with a propane burner and it has helped in the last of flower but I think a little late next run in a few weeks will tell for sure. Already have A/C so heat is not a problem.

Does anyone know what the right temps you can bring it up to ? That is of coarse if you keep your water cool.
