Does anyone here paintball? Bc if you do and do personal or closet grows a great way to supply co2 is to take a multitools needle nose to the pin in your CO2 tank. 20 oz tanks are the easiest to use bc they hold the most......just when you spray your plant be careful not to point the tank directly at your plant bc it is released at high pressure and might blow over or freeze and put your plant into shock. A slow controlled release is best and you can completely saturate your plant with CO2 every day.....a typical 20 Oz tank cost about $15. And $6 to fill. One tank will last your plant until harvest and will give your plant more CO2 then any other method out there.
