Most simple is probably the Dry Ice Method, most money efficent is Baking Soda+Vinager, just shake it every now and then, add more Vinager once all the Baking Soda has absorbed all the vinager, and like other posters have previously posted, redo every 2 days or so.

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
