you can get more co2 production and zero alcohol production, if you oxygenate the water.
then it wont smell as a brewery too, (smells kinda like a bakery instead)
if you have a large enough surface of the water, you simply need something to move the water around (this releases co2 from the water and intakes oxygen)
like a small aquarium filter or something.
if its a small surface, like a bottle, then a small airpump would be better.
yeast that doesnt receive oxygen(stagnant water), produces less co2 and alcohol as a byproduct and are killed eventually by the alcohol, while oxygen fed yeast can practically live forever and just need more sugar.
though the solution does tend to froth bit and that needs to be cleaned regularily.
this also consumes quite a bit more sugar, give it enough sugar and see the water explode with bubbles, nothing but co2 bubbles.
vast improvement from the oxygen starved yeast.
i wouldnt overdo it on the sugar, just try a bit, see how it goes with the plants, then increase sugar if needed (while it can consume pounds in a month, why you gonna buy all that sugar if you dont need it? better test to see how much is needed (when the plants dont look to be improving anymore, thats when you know how much sugar to give, id recommend some intervals between upping the dosage)
this really produces quite alot.
id also place the co2 lines above the plants, as co2 is heavier than air and sinks down.
btw, if the cab is refreshed constantly, fresh air in and old air instantly out of the room?
then even 4-5 pounds of sugar a month, aint gonna do all that much to improve the grow.
not enough to excuse all that extra trouble anyway.
it needs to be a more or less sealed room for this to work properly, a environment you have control over.
and as they say, co2
is what you add, when you have gotten Everything else right.
lol,thats kinda neat, how much does a candle produce co2vise? course there is the added heat, flame danger too, problematic in a small cab as well.
