2013-04-14· I have been in this game for a long time and common wisdom has always been to keep your CO2 levels at 1500 ppm for best results. Recently when doing some research I ran across a thread that says not to go over 1200 ppm and that 1100 was ideal. …
The Mauna Loa Observatory in Hawaii, which has tracked atmospheric CO2 levels since the late 1950s, on Saturday morning detected parts per million (ppm).
CO2. 250-400ppm. Normal background concentration in outdoor ambient air. 400-1,000ppm. Concentrations typical of occupied indoor spaces with good air exchange. 1,000-2,000ppm. Complaints of drowsiness and poor air. 2,000-5,000 ppm.

As seedlings or newly rooted clones they won't use up too much more than 400-600 ppm ( natures co2 ppm is 300-400ppm outside), as they plants grow raise the co2 ppm up towards 1000ppm when you are flipping to flower or 2-3 weeks of growth if they are clones. As they flower raise it up more and max out at around 1800-2000ppm co2. Some peeps max at 1500ppm. That is low for full sized flowering ...
