4 4 tent c02 for high 30-35 degree heat?

instead of forking out on expensive power bills to keep the grow below 30 can i add c02.

my tent is 4 by 4 avg temp is around 30 in this climate. i see a lot of people saying you need to get up to 1200 1500 ppm of c02 to make the plants want and handle high temp however a lot says if you reach this number of ppm you need a tent bigger than 4 4 ..

I am hoping i could pull this off with compress c02 with a regulator in my tent and take advantage of the hot heat and maybe tone down the c02 in the winter so I Can swap from 30-35c to ordinary 25-30 range (close as I Can get it without ac in the winter)

is this possible ?

Well the low end of your range is perfect for LED lighting since it lacks IR to warm the leaves. Perhaps with LED you could keep temps in that range as well. With LED you can run 86 or 87 F canopy temps with normal CO2 levels without issues.
