does anybody remember sience class? Remember making paper mache volcanos with the bicarbonate soda and vinager? well heres how it works. The reaction of baking powder (bicarb) and vinegar is used as an example of an irreversible reaction.
The nature of atoms and molecules is touched on enough to explain the reaction - how a solid (bicarb) and a liquid (vinegar) combine to make a gas (carbon dioxide).

Moral of the story get a container make a mini volcano in it in you growroom. Doing that once a day should do the trick!

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
