cool thats good to know thanks,i had plans of running co2 at night cuz i dont have to run exhuast as much,but now i wont lol

so are you saying if your above 10,000 lumes with floros you could still benifit from co2? i got 12,000 lumes in a large upright freezer could add 3,000 more mabye

also do you think air coming in from a basment would have enough co2 in it,not
to even bother with adding more?
thanks man ,peace
