We both are on the same page with the co2 get up. Im using co2 in my grow and you see amazing fast results. Raising the temp over 30c and pushing your co2 from there. Plants take in more co2 with temps over 30c I usually push mine to about 54c and then let em breath for a while. You dont want them to drop to 0. And to much co2 can kill your plants. Also dont run your co2 when the lights are off, its a waste. Plants dont take up co2 when its dark phase.
