Thanks for the replies, especially about the manual co2 gauge. I talked to a dispensary owner in Boulder who runs 95 degrees with 2000ppm's. He also uses co2 in veg and in cloning but the c02 level and temps are lower for the clones. However I won't bring my temps over 85 to start out with because I've seen multiple co2 grows stick with that maximum temp.

Can anyone recommend a reasonably priced co2 setup? I'm about to buy a 50lb tank and a regulator but I'd like to find a good price on a co2 controller/monitor
TurboALLWD Reviewed by TurboALLWD on . Ideal Grow Temp for 5,000ft elevation(sealed room) I need advice from experienced growers on the ideal temperature for a sealed room using co2. I've heard that it's lower than the normal 80-85 degrees. Rating: 5
