Sorry I didnt make it clear. The CO2 calculator in that link gives the amount of CO2 required in cubic feet. That's what I was wondering, how much baking soda would you need to react with vinegar to get required cubic feet of CO2?

From Newgroweroldsmoker: "when the sugar exhausts add some more..."
This seems like a very usable process. How do you tell that the sugar has exhausted? and will the water evaporate? if so, then you would just keep adding water to maintain the same volume?

you know when the sugar is exhausted by looking at the liquid you prepared if it still bubbles.....make sure you throw in the amounts i gave you earlier and for sure double the sugar....4 days have passed and mine is still bubbling....you'll see small and medium sized bubbles emerging evey sec top the top......don't worry it's going to work
newgroweroldsmoker Reviewed by newgroweroldsmoker on . CO2 in the grow room I have a 2'x2'X3' grow room. I read about adding CO2 to your room to make the plants grow better. In a book I read, the Cannabis Grow Bible, it said that CO2 can possibly double your yeild. What I was thinking, since CO2 generators are expensive, to do the baking soda and vinegar reaction that will release CO2. I calculated about 1 lb of baking soda reacted completely with vinegar every other day inside the grow room will give the plants plenty of CO2. Just an interesting thought. Any comments? Rating: 5
