Co2 "exhale bags" or similar. What's your opinion?

Do they work? What's your experience with them?

There is a section on grow bags......I do that thang , however I do get tired of hyperventilating and passing - out . I should hire some young kids with a good set of lungs to do this dirty deed .

Lots of anecdotal claims pro and con, but I didn't see anyone who did head to head grow reports where the only variable was CO2 bags.
OTOH I've seen the results of a controlled environment with regulated atmospheric conditions but that's a $7.5M grow room. Even for them it's probably overkill because they'd have commercial quality results anyway.

[edit] and that's tanks not bags

Same Shit

Waste of money, i have a good CO2 meter and the difference is hard to even measure. Me just being in the room for a few minutes raises the ppm more.
