I haven't rolled CO2 yet, but I'm planning on it, and I can confirm from many, many discussions, that CO2 is best absorbed by plants that are in an elevated temperature range, 90-95 F.

Think of the benefits too, you run your AC unit less = more $$ in your pocket instead of the utility co. and with CO2 you have the potential to produce more product in the end.

I'm not saying don't do the AC, you're gonna need it too in SoCal.

Good luck with your project!

p.s. I have 2 master kush that are about a week or two from flower. As soon as I get back from Vegas, I'm cloning them.
