Organic Black King Mushroom Grow Kit Fruiting Block

Our black king (Pleurotus spp.) fruiting block features a strain that produces some of the heartiest mushrooms available for indoor cultivation. This hybrid strain grows mushrooms that are succulent and savory like blue oysters, but with the dense texture of a king trumpet. Black kings are less finicky than king trumpets and grow very well indoors. When cultivated successfully, you can expect a large harvest of meaty and delicious mushrooms. However, 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.
