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 |
|---|---|---|
| Bed warmer than room air (oyster) | 2-4 degrees C | ICAR-DMR manual, 2011. Measure with a probe inside the bag, not the wall thermometer. |
| Spawn use-by period | Supplier protocol | MushroomFarming.in guide. Species, strain, production and storage conditions matter; no universal 30-day limit. |
