I guarentee you there is no sugar in club soda. All it is is WATER that is CARBONATED. Its exactly like regular water... only... carbonated... So i dont see how it can mold plants or cause mildew... please someone help!

As for the tablets you place in the reservoir.. Each tab only last 8 hours... and thats a lot of money :/

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
