Just a heads-up I seen something for sale that looked pretty good. It's a small bucket that has fungi or something inside there that releases CO2 at a good rate for a few months.... it was a grow product and cost £100, you can find it on a few websites but im not sure of the exact name.

I've also heard of using carbonated water is feeding but I havn't looked into it. Would be interesting to hear more about the club soda..
KHAN Reviewed by KHAN on . Help me with a CO2 Question Okay, I saw on a grow video (from pot.tv) that if you cant afford a CO2 tank (which I cant) the next bext thing is to get Club Soda and a spray bottle. My question is this: Once flowering begins, do you mist the club soda onto the flowers also, or just the fan leaves ? Please help :thumbsup: Rating: 5
