These figures belong to the named source and method. Historical costs are not current quotations. A value without its stage, material basis or measurement location is not a farm instruction.
| What is measured | Value and basis | Source and limitation |
|---|---|---|
| Button spawn run | 12-14 days | ICAR-DMR manual, 2011. Then casing; the farmer folder says 12-15. |
| Button case run | about 7 days | ICAR-DMR manual, 2011. Mycelium seen in the casing valleys marks the end. |
