Spawn = 10-20% of substrate wet weight

PasteurizationStandard

Heat substrate to 160°F for 1 hour or use lime bath for cold pasteurization.

  • Identify Before Eating

    Only consume mushrooms you have confirmed as Pleurotus ostreatus — misidentification causes serious illness.

  • Squeeze Test

    Substrate hydration is correct when a handful releases a few drops, not a stream of water.

  • Bucket Reuse

    After harvest, buckets can be re-pasteurized and re-inoculated — substrate cost is the main expense.

Safety Notes

  • Only consume mushrooms positively identified as the cultivated species — wild lookalikes can be toxic.
  • Green or black mold on substrate means contamination — discard immediately and do not inhale spores.
