Hi. im useing constant carbon doixide at 3 cubic feet a hour. my temperature is 68 to 72 degrees.. i know that to warm of a temperature (especially) in flowering is not good... this being said, my question to all you growers that use co 2 is.. what is the proper temperature to have when useing co 2. thanks...

I've used 86-90 in my flowering room for 6 months, and around 82-86 in the veg room. And I was around 1500ppm co2 in the veg and 2000ppm in the flowering room.
There's 108 different opinions of what the proper temperatures are. I don't know if there is a 'proper' temp really. You can read and read about what ideal conditions are, and then you'll see some grower use something totally outside of that range and get killer yields with no issues.
