How long is a piece of string. ?
It depends on what the stuff is, how much air is in the mix, how wet it is, as well as temperature.
Drier stuff takes a lot longer.
Softer stuff ike grass cuttings decomposes faster than oak chippings.
I try and mix it all up as well as I can, make sure it is damp and then stand back. Two weeks of heating up and cooling down, and I mix it again. Then the brandlings move in. Second stage can take six months.
