I have the autopilot co2 monitor, and titan co2 regulator. 20lb co2 tank. My grow room is 1008 cubic feet. Co2 shuts off when lights out. But the have questions… the ball float on regulator what should I adjust it to? And what should I set my autopilot to ? My grow room is sealed room.
Would the ball float be at 15? If I wanted co2 at 1200ppm? Seems like it would empty tank quicker or is that not how it works? Also on the co2 tank do I open full or just crack it open a little?
