whens the best time 2 stop using co2?

[dankhead]

ive read that co2 in flowering can be detrimental. should i not supplement co2 during flowering at all?

Use it all the way through flower until the last two weeks, then cut it off completely. 1200-1500 ppm.

run your co2 only during your "ON" time. make sure its off when they sleep. Thats a no no.

I neglected running the co2 because I have a shat ton of fresh air coming thru. It'd be nice to know at what point makes co2 harmful to grows

I run it start to end. Lots of speculation around, I just don't see the logic in cutting it off late in flower. The plants stop breathing when they get older or something? :D I'll be happy to learn so if anyone can explain how it EVER can be detrimental, (In a sealed room) please let me know. Maybe wasteful but propane is cheap... :)
