I saw listing on ebay they has CO2 tank for paint ball gun/beer dispense (not sure if it contain CO2.) can you feed these type of CO2 to the plants or they are two different things?

can you purchase CO2 for the plant?
shiloh Reviewed by shiloh on . CO2 - how to? I have heard a lot of good things about CO2 -- So, I decided to mix one myself. My question is how do I use it? Do I just spray my home made CO2 into the plant? or do I have to add some water afterward? please advise. thanks Rating: 5
