FWIW, the use of term "composting" isn't really accurate unless you mean in a compost pile, or do you mean in media?
Well in the sense in which I use it the meaning is much looser, which yes, is technically inaccurate. On the other hand it is more versatile and gets my point across to a wide range of people.
so what would you call it in general? bacterial degradation? I don't know. I want to indicate making it a relatively stable food source for the right microbes I guess.
and what do I call what I do with the worms? I mean, sometimes I get quite a bit of heat (in winter). And I do have outside soil in there. What do I call the castings and mostly finished food items?
