Some are saying chemical processes, time or heat dependent. Yet presumably these would occur just the same in bone dry weed. Perhaps the drying is simply a means of concentrating the solute into the remaining liquid. Yet this would suggest chemical reaction rather than simple decay. Suppression of molds certainly occurs, yet are we seeing fermentation, much like how black tea is made. Sealing the weed is mason jars suggests we are deliberately attempting anaerobic fermentation, we even off-gas by burping them. Far from seeking oxidation of chlorophyll, we are oxygen deficient. Take water cured weed for example. A tasteless, odourless product, exactly what some people want. It is still noticeably stronger after sitting in the bag for a month then when first produced. Thus there is still some chemistry going on. It is not the THCA to THC, since I have oven baked to induce that and the weed is no stronger.
