The Black Pearl King Mushroom, produces some of the heartiest mushrooms available for indoor cultivation. This hybrid strain grows mushrooms that are succulent and savory and tender like blue oysters, but with the large size of the king oyster. These Oysters are reliable producers and tend to yield large flushes of beautiful mushrooms when given adequate humidity. 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.
