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
