Organic Pioppino Mushroom Grain Spawn
Our USDA-certified organic pioppino (Agrocybe aegerita)grain spawn features a strain that fruits clusters of snappy-stalked, medium-to-large mushrooms with velvety brown caps. Pioppino is a relatively fast substrate colonizer but can be very finicky, which requires some patience and precision. Oyster Mushroom Grain Spawn

Pioppinos prefer cooler temperatures and are prone to drying out or halting their growth if humidity is not maintained when the mushrooms are still in their early stages. However, when they grow successfully you can expect decent harvests of these delicious mushrooms. They do not reliably produce second flushes, but may produce if conditions remain controlled and humidity is correct.
Recommended use:
- Pioppino grain spawn can be used for indoor production using sawdust-based sterile substrate.
- Do not use grain spawn for log inoculation.
- This is not a mushroom grow kit. Pioppino grain spawn must be combined with a substrate in order to fruit.
Upon receiving your spawn:
Remove it from the shipping box as soon as possible. Then, unfold the top of the bag, making room for air space. It’s also important to check and confirm that the filter patch is not obstructed. This will help the organism breathe and continue to thrive!

Temperature | 55-65°F | 13-18°C |
Humidity (Phase 1: Primordia) | 95-100% |
Humidity (Phase 2: Fruitbody) | 85-95% |
CO2 Sensitivity (Phase 1: Primordia) | <2,000 ppm |
CO2 Sensitivity(Phase 2: Fruitbody) | <2,000 ppm |
- Primordia – The earliest recognizable stage of fruitbody development. Also known as “baby mushrooms” or “mushroom pins.”
- Fruitbody – A fully grown mushroom, the reproductive structure of the organism in which the spores are produced.
- CO2 sensitivity – When CO2 levels are too high, yields will decrease, stems will become long and stringy, caps will be small, and/or growth will halt.
