Guys, we all know why CO2 is used and it's benefits. I have seen recently a video on Youtube where a guy who uses a CO2 set up mentions that if you don't have this option you can spray Soda Water on your budding plants. Im wanting to do this and wan't to know. Should I keep my spray bottle in the fridge. Will the temperature being cold shock my plants. Should I just keep the Soda Water at room temperature in the spray bottle. Will I loose too much of the CO2 in the Soda Water if it isn't kept refrigerated. Some much appreciated advice please. Peace dudes.
