Spawning should follow a documented release decision. Confirm that conditioning and cooling are complete under the selected production protocol. Use suitable calibrated instruments and representative sampling; record temperature, moisture and validated ammonia results against that protocol.
Do not infer an ammonia concentration from smell or deliberately inhale compost gases. A lack of smell does not prove safe working conditions or crop readiness. If a criterion is unresolved, hold the batch and obtain a competent assessment before adding spawn.
