You need took a little further into why the plant needs CO2 to survive. The plant can only absorb C02 during the dark period of the plants life. When the lights are on it's useless. It's best to flood the growing chamber while the fans are off so the plant can absorb the C02. It still blows my mind that people don't bother to read about growing. It's not that hard, there are plenty of books and there is this web site. Basically you can find anything there is about growing and how to do it.

"Photosynthesis (English pronunciation: /foʊtoʊˈsɪnθəsɪs/; from the Greek φώτο- [photo-], "light," and σύνθεσις [synthesis], "putting together", "composition") is a chemical process that converts carbon dioxide into organic compounds, especially sugars, using the energy from sunlight"

Are you sure you know what you are talking about?

first off co2 only is used in the light period never in the dark. second co2 is like herion for people once you use it you always need it and if you stop giving your plants co2 they will go into a withdraw like state and die. third unless you have a big setup and are trying to make a living from it co2 is pointless for the hobbiest. there is alot to using co2 you need 1500ppm of co2, to get that correct you need a meter, and solinoid, your grow space must be somewhat air tight or the co2 will fall to the floor and disapate, your plants will and can recieve a higher dose of nutrients which costs more and if your conditions are good to start with there is not that much difference in overall wieght compard to the cost of everything you've been spending. I have tried the co2 boost it does work but not enough for me to buy another for that price and I know the guy who invented it and I got it for free, so what does that tell you. Take your co2 bottle and buy a kegerator its a better use for the co2. be careful when you just squirt the co2 in your area remember we don't breathe co2 we need oxygen to live if you squirt to much you can pass out from oxygen depravation and fall into a layer of co2 and die. use caution be careful and good luck.
