Organic Black King Mushroom Grain Spawn

Black Kings (Pleurotus spp.) produce hearty mushrooms with beautiful brown marbled caps and soft stems. When cultivated successfully, you can expect a large harvest of very meaty and delicious mushrooms. Black kings are less finicky than king trumpets and grow very well indoors. They prefer cooler temperatures and are prone to drying out or stopping their growth if humidity is not maintained when the mushrooms are still in their early stages. They require high CO2 to achieve delicate, long stems, but can also be fruited like oysters.

Black king grain spawn can be used for indoor production using sawdust-based sterile substrate.

Do not use grain spawn for log inoculation.
