I remember seeing in a grow video, I grow chronic i think it was, where he took baking soda and vinager and mixed them together. They both started to bubble up creating co2, probably do a search to find a more detailed explaination.
t3chyo Reviewed by t3chyo on . how do you regulate the CO2? Would i be able to spray seltzer water on the plants (carbonated water...with CO2) to deliver CO2? does anybody do this? i can't think of any other way to deliver a good amount of CO2. Rating: 5
