Growing details

SPECIES DESCRIPTION

Species name: Pleurotus sp. "Shimofuri hiratake" or Black Pearl King

The Black Pearl King Oyster is new in the world of mushroom growing! This strain is a hybrid between a King Oyster and a Peal Oyster, cross-bred in Japan. Its Japanese name, Shimofuri, means 'marbled' and refers to its beautiful speckled caps which almost look like stars in the night sky against the dark pin heads during early growth.  

This hybrid displays favourable traits from both parent species, forming dense clusters of King Oyster-like mushrooms with dark caps. Unlike other Oyster varieties, the stems of the Black Pearl King are great to eat (similar to the King Oyster) and are very meaty and juicy and easily pull apart.

Interestingly we have found this hybrid to be spore-less.

PREFERRED SUBSTRATE

Black Pearl Kings can be grown on a variety of substrates including hardwood sawdust, barley straw, and sugarcane mulch.

For highest yields and heaviest clusters grow on supplemented hardwood sawdust or Masters' Mix.

INCUBATION

Incubation period: 18 - 21 days (depends on substrate). Average incubation period is 21 days.

Incubation temperature: Room temperature between 21 - 24°C. Do not let the substrate temperature exceed 30°C.

Pinning humidity: 90 - 95% relative humidity
