well i was thinking the phosphoric acid would make a good PH down, i know the CO2 is used by the leaves but im not quite sure what it would do to the roots, and even the carbonic acid may down the ph noticably.
i find growing organic creates/uses more chemicals than nonorganic. compost bins filled with food scraps and whatever u put in it has chemicals proteins enzymes, which all gets broken down and recombined by microbes. i personally think more chemicals than fert sticks and ph +/- ferts. ppl always talk about coffee grounds being good and that is loaded with caffeine, how is caffeine good for plants?
i might actually water one of my plants with pop when it buds, im kinda worried that the caffeine might kill it.
