Co2 And paintball guns?

Hey Bus driver here, i am just wondering.... because co2 is good for your plants can i rig something up with a 20oz paintball tank? or does anyone know what kind of device i can use on a small co2 tank that can regulate the co2 coming out of the tank.... i do not have the funds to buy a big co2 tank from a seller.... any isea about using a paintball co2 tank?

i have something like what your thinking, i havent set it up for a grow yet but i used it on my car as a intercooler spreyer but since i dont have the car anymore i figured i could just wire it to a time, the tank size is kinda small but as long as you dont mind filling it up everyonce and a while.
anyways i used the dropforward and bottle from an older paintball gun and then where the line would go into the gun it's connected to a nitrous purge valve, and since it was on a switch before i figured i could wire it the same way but having a time instead of a switch but having a timer that could sprey for a short enough time could be hard to get
