Evidence brief: readiness and scheduling in indoor shiitake
How can a grower distinguish calendar age, block readiness and harvest performance?
Scope of this review
Indoor sawdust-block cultivation of Lentinula edodes. Natural-log production schedules are outside the scope.
How we assessed the evidence
Sources checked on 5 October 2026. We compared university cultivation guidance, primary research and technical measurement literature. We distinguish published observations from Hamfy's proposed operating records and illustrative calculations; this is an editorial synthesis, not a systematic review or a farm trial.
What the evidence supports
Colonisation is not the final handover
Maturation and browning belong in the block history.
Protocols are system-specific
Induction instructions need to match the strain and substrate.
Repeated flushes need linked records
A total harvest weight alone hides the time and losses between flushes.
What this review does not establish
- The university production overview describes historical systems and cannot specify a modern supplier's exact schedule.
- No Hamfy cultivation experiment or validated visual readiness model is reported.
Hamfy’s proposed next step
Use the framework to define a monitoring brief with the grower: species, strain, crop stage, room layout, sensor locations and records needed to test a specific question.
Evidence to collect for a real project
- A named strain and supplier protocol.
- Timestamped room and substrate measurements linked to a batch.
- Comparable harvest, rejection and resource-use records across repeated cycles.
