Black Pearl King Oyster (Pleurotus ostreatus) is a hybrid between 2 Pleurotus ostreatus (Pearl Oyster) strains and grows much like Pleurotus eryngii (King Oyster). Black Pearl Kings are less finicky than Pleurotus eryngii, and are able to grow very well indoors. Grows on the same substrates as pearl or king oysters such as masters mix or hardwood sawdust (HWFP). It is a fast substrate colonizer that fruits dense, meaty mushrooms.

Fruiting Conditions:

Temperature: 50-68F

Humidity: 90-95%
