if you tried using the 1.5's it would probably take a good hundred thousand to get up to the proper levels for the needed amount of time.
keeko Reviewed by keeko on . CO2 cartridge question I've got a question about getting CO2 into your grow room. What about cracking open the small CO2 cartridges that you use to play paintball? Each one has 1.5g of Co2 under pressure (im pretty sure about that) and I know you can buy crackers that you use for whip-its...which i could sub out for my room. Does anyone know anything about this? How much co2 would you think to use? IDK how economical this is, but we have a lot of paintball guns so there is quite a collection of the little buggers Rating: 5
