When to start Co2

[nemgrower202]

Hi
In a closed co2 grow room do you start co2 supplementing in the first stages of flowering or do you start the co2 from beginning to end of crop since its a closed room?
Thanks

I run Co2 all the time but at differing ppm. 400-600ppm for seedlings then as i push the light around 800-1200ppm for mid veg and flower. I drop my co2 later in flower like last 2 weeks back to 800ppm

I just run it at 1500 ppm all the time. To be honest my cost to fill a bottle is either 10 or 15 bucks so the cost is not an issue.

Cool, and do you guys really see a noticeable difference with the co2? I've never tried it before but now i have a setup for it and wondering if it worth the hassle.

If you have the lighting to make use of the Co2 you will see a difference.

I run co2 in a tent 1300ppm, all stages, temps and light need to be pushin it.. I may be mistaken, usable co2 will increase with those parameter..
