CO2 bags?

If you know how to grow you don't need to waste money on CO2 for such a small increase in final yield...

I agree when the lights are ON, sorry if you misunderstood me, PEACE!!!!

I have the co2 buddy boost. Not sure how much it helps but I have a small locker grow and the bag takes up to much space and it stinks the hell out of the room it's in.

Yea, I feel they do/might help in seedling and vegation stage and not in flower, but the main concern is the area coverage, if done right they will work
