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 around. It can't hurt, but do you know how much it could help???

ha, i don't use it often, but that's what i use. unless you have a sealed room, co2 is pretty much a waste. all the equip. is expensive. all you really need is good airflow/exchange. i use a hand held bicycle tire inflator to use those co2 cartridges. just make sure to turn off the fans.

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.

yeah thats kinda what i figured
