The start date is the first day food waste went in.
Smell and squeeze
Visuals can be deceiving here, so rely on your sense of smell. Regardless of how good it looks, any trace of a sour or ammonia odor indicates it needs more time.
Squeeze a handful of compost, then open your palm.
Our SOP says two to three times a week. More than four days is already late — air stops getting in and the process stalls.

Reading the photo…
Five photos are taken and averaged, so the result does not jump around.
Have a thermometer? (optional)
Seed germination test
The final check — free, needs no equipment, and makes a good science activity for the children. Soak compost in water, wet cotton wool with that water, sow 10 mustard seeds. Count after four days.
It passes if 80% or more sprout — 8 out of 10.
