Key benchmarks for mushroom harvest timing.
| Species | Signal | Window |
|---|---|---|
| Oyster | Cap flattening | 24-48 hr |
| Shiitake | Cap 50% open | 1-2 days |
| Button | Veil intact | Hours |
Oyster mushrooms go from perfect to over-mature in 24 hours — check fruiting blocks twice daily.
First flush yields 50-70% of total production — prioritize labor and timing for flush one.
Mushrooms lose 50% of value after 5 days refrigerated — harvest only what you can sell or use within a week.
