I saw once someone spraying their plants with carbonated (sparkling) water, saying that it was a good way to increase C02 intake in their plants.
Is there any truth to this?
Depends on the ph, im not into hair brained ideas, I use things I know work for me, such as distiled water etc....but great ideas come from experiments, ill let others try lolz.
ed rosenthal said that it would have minimum effects. if you think about it, the plants would only be able to use the tiny bit of co that is released and then its gone. you would have to mist constantly and then you would have big problems. look into dry ice.
