Record: Compost temperature, validated ammonia and moisture results, spawn lot and strain, kg compost, g spawn and bags filled.
Two days ahead, confirm the spawn lot, its manufacture date and the strain in writing.
Before spawning, record representative compost temperature, moisture and validated ammonia results against the release specification.
Weigh the spawn against the actual wet weight of compost, not an estimate.
Fill and label every bag with batch, date and strain before leaving.
