cheap CO2
Hello everyone,
I was thinking about a cheap way to use CO2 on your plants. On ebay they sell a box of 16 12-Gram CO2 cartridges for less than $5 per box for disposable use in paint ball. I am curious if I was able to use a whippet hand cracker to leak these into a balloon and blew the CO2 onto plants, if it would help the plants?
One could blow 200 grams of CO2 over a weeks time, every week for $5 per week.
Any thoughts?
