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?
Well i dont know about all that. When it comes to growing I like to think simple, not in C02 or any of that. Basically, fresh air is your friend.
Not true rasta, you could have fresh air circulating in and out of the plants, but CO2 would do the ultimate growing trick. CO2 can doulbe your yield, if it doesnt double, your bound to get more then the usual :D.
lol very true, can't go wrong with simplicity. I was just curious to see if anyone thought to do the baking soda and vinegar reaction. Thanks for the comment, hope your new grow room works out great for you Rasta.
I my self have never thought about that... but my friend there is always Trial and Error , so have at er.
Ill be the geuni pig this time :( lol i have a grow coming up anyway, but apporx. how much would u have to use and how often???
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!
Hmm rasta, I wouldnt exactly know on how much to use because I my self have never used CO2 because I get the normal yield and most the time a higher yield. I would suggest posting this in Advanced Techniques, where others with more knowledge can get to ya. Anyways good luck with that grow rasta! and dont forget to make a log on cannabis.com ;D.
Oh, and don't do this during the dark hours (if you're flowering) because plants do not do photosynthesis during the night so it'd be useless.

There's a calculater for your help. Yes you shouldnt do this without your lights on, like he said photosynthesis.
How do you convert cubic feet to grams or ounces of baking soda. That's the tricky part, lol. I already used a similar calculator, actually the equation, to get the cubic feet of CO2.
Cubic feet have nothing to do with grams or ounces of 'baking soda'. It wants to know the size of your grow room, the CO2 depends on that, it has to fill the room and the lights vaporize it onto your plants...
The reason why you cant convert Cubic feet into grams or ounces is a simple question, How many cubic feet are in a gram? hahahahaha 0.
baking soda+vinegar is good for CO2 production but lasts very little...really it does work for a while...what you need is a more durable solution, a one that lasts lon ger than 10 minutes only and costs the same.....mix the following into a bucket/bottle
i will use a 2lt bottle as the standard unit here......mix 1/4 teaspn (1teaspn=5grams) active yeast with 1lt warm water and shake hard for yeist to dissolve....then add 2 cups of sugar (1cup=110grams)....add 1/2 lt more water and shake even more (with the cap closed)....open the cap and leave the bottle open in the grow room....by this way you'll have constant production of CO2 for 4-5 weeks...it will smell yeisty in the beginning, a smell which will develop into some a little awful smell.....when the sugar exhausts add some more to enable more cO2 production....so if you increase the number of units (2lt bottles) you'll get plenty of CO2 guaranteed...only be careful when you add the sugar, if you thrown in large amounts it bubbles like hell....this procedure is called fermentation...it's hard to tell the exact amounts of CO2 being released but you'll surely see the difference....can't tell if you'll double the yield but remember that, any positive input of your part will be greatly appreciated by your plants and in the end you're gonna be rewarded for your efforts.....
PS. lol, sorry but 1lb=450 grams approx. you'll need a lot of vinegar for that....the above method comes a lot cheaper and lasts longer:)
cool idea! did you create this technique or where did u get it from?
if you already own a vinyard then it's ok to go for it with the baking soda....if you want to spend all your money bying vinegar and make the owner of the convenience store happy go for it with the baking soda, if not buy some sugar......
in your case i see this.....fill a tank with 20-30 lt warm water, warm not hot....put a cube of 25grams of active yeist in it and mix it well so as it dissolves......add then 4 kilograms of sugar gradually, do not inhale, pure CO2 in great amounts will come up......place from before all that setup in front of your plants and while you do it have a fan blowing the tank (and subsequently your plants)..all the co2 produced will be directed in there....
now comes the ''dirty''work.....CO2 is heavier than air, which means that once it is being produced it falls down....so this method is good if you can find a way to give them the CO2 from above.....the ''dirty'' work comes when you start filling those bottles of the tanks' content...place these bottles in your grow room wherever you can...as long as they are placed at a higher level you will be almost certain that the CO2 produced is actually being consumed as it will fall on the plants...
i call it dirty as it is very sticky business, with all that sugar involved;)

From Joel: "Cubic feet have nothing to do with grams or ounces of 'baking soda'."
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?
good homegrown ideas fellas, I'm gonna try the yeast/sugar/warm water, thanks
Thanks for the advice Newgroweroldsmoker! I have 4 bottles full fermenting in my grow room! Hope it'll help my plants.

Ah, makes so much sense. Thanks a bunch!
