CO2 has been used in grow operation across the planet to produce larger flowers on cannabis plants for years now. It will definitely give your plants a boost, but you have to be careful with the ratios you use. Too much is actually stressfull to the plant. In tandem with that comes PAR readings(amount of light available for growth) and co2 ratios. To high of a par, or too strong of a light without co2 is also stressful. Its an interesting thing to mess with, and its relatively similar with mostly all plants, not just cannabis.
