Thanks Rasta. So here's what me and some of my bioengineering friends calculated (They used equations and shit I'd never seen before, so hopefully they're right). React 723 grams of baking soda completely with vinegar for a 200 cubic foot room, we guessed approx. 627grams of vinegar for this reaction. This equation, however, is more than enough, so you can however much or however little you want. And i would do this every other day or every third day. I don't know how fast the reaction proceeds, so you might not want to do it all at once and have all the CO2 ventilated out of the room. I would really like to know how well it works. Thanks again Rasta!
