i dunno what you mean carbonated water?? dont feed that to your plant... the roots need o2, the plant above the ground needs co2... proper ventilation / air exchange will provide enough co2 easily... and if you want to give the roots a boost, bury an airstone at the bottom of your pot to increase o2 to the roots
I don't think the plants are actually watered with the stuff. I have used the charged water method, and it is ok. I have misted plants with it to add a little CO2 before the lights came on. Not a bad way to add a little humidity, and CO2 in one shot.
