Hey Cyclonite,

I'm a little unclear why you are using an AC inside the cab. If your running a cooltube for your light (what size?) then the cab should only rise abt 10 or so degrees above ambient temps, even with 1000w.

Next, need to know what your source of CO2 is. If it's a tank you can use a sequence timer to shut off gas while AC runs, but it will still pull the CO2 out of the cab that's already there.

Currently in a "quick, dirty and cheap" temporary grow I'm doing with a partner, I'm using a very oldtime method for CO2.... 1/2 gal jugs 1/2 filled with warm water, with sugar and yeast. We have about 6 currently sitting on the grow table (4'x8') with our plants. Cost less the $2.50 (for all six) and lasts about 2 weeks.
