i would think even two days would be plenty of time for some level of fermentation to occur,and even without it any form of plant material is going to have some level of plant sugars in it,whether or not there is enough sugar present in those solutions is open to speculation i guess.
Sprout teas and sprouts should not go anerobic. Fermentation is an anerobic process. We are after the plant hormones and secondary metabolites that the living sprouts contain. Sprout-puree-dilute-apply is what i do. I add some fulvic acid and only bubble if its sitting for awhile.
