I use the exhale co2 bags as a supplement but don’t think they’re big producers of co2. I don’t measure it but the bags last about 2 grows for $30 so I figure why not

And have you seen any difference, any bushier growth, fatter, denser buds perhaps?

I’m not the best at keeping track of improvements but I would say my grows have gotten better since I’ve added that bag. I’ve also learned a lot more so can’t say with certainty. If you can afford it, it’s worth trying for sure I’d say

homemade CO2 factory… alcohol byproduct CO2 filtered through water pushed into the grow room, all by itself… however not my idea, just adopted from our good @snAke

Super cool.. and have you already noticed changes regarding pistil production or bud density, or thicker stems or leaves, like a shinier, green, and thick waxy color? I don’t know, maybe some opinion or difference between using CO2 and not using CO2, because I have the same system, a one-liter bottle for the bubbling water and another 6 L bottle for yeast fermentation with sugar. But it looks super cool, I use it with IV tubing because I think the thick one didn’t handle the pressure, right?

This is basically the same but without water filter. The only problem I have with it, is not having any control over the ppm.

A hermetically sealed grow room is da biggest thing missing 
But CO2 should help.
Just remember about respiration, when plants produce co2 and require oxygen instead.
Again, Im pretty inexperienced witt this stuff.

Oxygen is required for respiration 24/7, which does produce CO2, but doesn’t produce the volume required for photosynthesis during lights on . . . a net consumer of CO2 so we may want to supplement.
Photosynthesis requires CO2 and produces more than the volume of oxygen required for respiration 24/7 . . . a net producer of oxygen.

someone like me would just read carbondyoxide for every chemical and missinterpret
