Organic King Trumpet Mushroom Grain Spawn

King Trumpets (Pleurotus eryngii) produce large flushes of meaty and delicious mushrooms that are earthy, aromatic, and savory. However, unlike other oyster varieties, king trumpets can be more difficult because they prefer cooler temperatures and are prone to drying out or stopping their growth if humidity is not maintained in the early stages. They also do not reliably produce second flushes, but may if temperature and humidity conditions are well controlled.

King trumpet grain spawn can be used for indoor production using sawdust-based sterile substrate.

Do not use grain spawn for log inoculation.
