Funny you mention beer haha I have a brewery and always wondered about piping it through to the flower tent. End of the day ita just not worth the hassleThe bags are a joke. You need more CO2 than those bags could ever offer according to the laws of physics. You need more weight in CO2 than the bag weighs. That should tell you something.
Brew beer if you want to go natural/no-tank. You will likely have an excess of beer...
