Hi I’m using a co2 burner in my grow room and I keep ppm between 1400/1500.. the question I have,do the room need to stay at that level the whole time the lights are on..the burner goes off at night..I have to replace my tank often if I keep the levels that high the whole time my lights are on

CO2 with light. Most growers seem to turn it off at night. I skimmed through this article and it has some good info with sources: https://ggs-greenhouse.com/blog/5-reasons-why-co2-levels-are-controlled-at-night
