however when the co2 breaks off from the water, it gases the area around the plant, providing a co2 rich environment, which i believe would reach the stomata.. so i would say to do water the soil with the mineral/carbonated water (ie seltzer) and isolate the plant, so that the co2 builds up around it instead of going off into the other space..
