Determining the Amount of CO2 to Release into the Growroom The first step is to determine the capacity or size of the room in cubic feet. Measure the length X width X height of the room. A room that is 10 X 10 with an 8 foot ceiling is 800 cubic feet. Determining the amount of CO2 that must be released to bring the growroom to 1500 ppm is done by multiplying the number of cubic feet in the room by .0015. 1.2 cubic feet of CO2 gas is required to enrich the air in the room to the desired 1500 ppm of CO2. this is part of the suggestion that i got from a master in marijuana seeds and he shared his great knowledge with me.
