Workflow
Calculate Flush Yield
45 minutesEstimate first and subsequent flush yields as percentage of total production.
Prepare Harvest Tools
2-4 hoursClean harvest containers, sharpen knife, and set up drying or refrigeration for immediate post-harvest handling.
Harvest and Document
1 hourHarvest at peak maturity, weigh yield per flush, and record timing for future grow cycle optimization.
Tools Used
- Hydroponic Yield EstimatorPrimary
Estimate yield per flush and compare to actual harvest weights.
- Seed-to-Harvest TimerPrimary
Track days from pinning to harvest for each flush.
- Microgreen Tray DensitySupporting
Calculate harvest density and tray coverage at peak maturity.
- Hydroponic Power CostReference
Compare revenue per flush against grow room power costs.

Harvest TimingTable
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 |
Flush YieldFormula
First flush = 50-70% total yield — subsequent flushes smaller
Over-MatureStandard
Spore drop on gills reduces shelf life and flavor.
Harvest Window
Oyster mushrooms go from perfect to over-mature in 24 hours — check fruiting blocks twice daily.
First Flush Priority
First flush yields 50-70% of total production — prioritize labor and timing for flush one.
Sell Fresh Fast
Mushrooms lose 50% of value after 5 days refrigerated — harvest only what you can sell or use within a week.
Safety Notes
- Positively identify every mushroom before consumption — only eat specimens confirmed as the cultivated species.
- Wear N95 mask when harvesting large flushes — spore exposure causes allergic sensitization over time.
