Sweet setup! I don't think the potency of the tea will degrade that much by wednesday. I would just stir it really well before using it. What are the dimensions of your loop house? I want to end the season indoors.
Yes. With high temps your tea will go anaerobic and start to smell sour. Then it is no good. Bad bacteria have already taken over. The longest I have kept a tea is for 36 hours from the start time. After that it can get real nasty. Sometimes on 100 degree days the tea will smell ready after 16 hours. if I let it go 24 hrs it will start to smell sour.
yeah honey or molasses each night it brews. last one had a few chunks of banana, some peels and oats to try to keep the sugars available the entire brew. of course a bunch of other stuff. new(for me) was some frass from a hollow in a tree.
