I didn't read that photo before - the Streptomyces are probably "decomposers" but I don't know about the others. Maybe all are for composting, and only the "endo MR" was intended as root fungi.
Certainly you'll have billions or trillions in a compost pile within a few days of having any at all.
Did I understand correctly that you're making the tea from scratch each time, from store-bought ingredients, that you don't have an actual pile of decomposing vegetation to make tea from?
>> "Science" has produced a lot of nonsense, especially lately.
It's kind of too bad that every science has become so specialized that their "reality" is the cluster of theories and experimental methods that are currently "hot" or "popular" enough to make publications likely. The days when a scientist "studied nature" rather than just the most esoteric details of their particular specialty are long, long past.
My guess is that it isn't even "science" we should be talking about. If they are studying "what works well in the field" , they are really doing engineering.
