I think it would bubble off too fast, so you would have a good level of CO2 for a few minutes, then the plants would use it all, or it would out gas. You would have to dose it every few minutes all day long.
Anything you get to auto-dose usually will have the carbonated water exposed to the air, so it will lose the CO2 anyway.
