Black Pearl King Oyster (Pleurotus Ostreatus - Hybrid)

Black Pearl King Oyster originating from Japan as a hybrid between European and Asian Oyster Mushrooms. This genus of Oyster Mushroom displays beautiful black caps, flavors or aromatic woody smells and meaty texture.

Patience & Waiting Stage - Spawn Run/Colonization

1. Spawn Run (Colonization) – allow inoculated mushroom grow kit to incubate at room temperature. This will take 2 to 3 weeks. Move onto next stage once grow kit is dense and uniformly covered with white mycelium.

Observation Stage - Primordial/Pinhead Formation

2. Pinning (Initiate Mushroom Formation) – Drop Temperature, increase Relative Humidity. Watch for mycelium to form Pin like growths and small mushrooms. Move onto the next stage once mushrooms are visible.

Action Stage - Fruiting

3. Cut small x or poke 1/8” holes in the side of the bag for mushrooms to grow through. Alternatively with the gusseted plastic bags simply cut off the top of the bag and gentle roll/fold the bag down to the top of the mushroom block.

 4. Fruiting (Mushroom Formation) – Adjust Temperature and Relative Humidity. Provide plenty of Fresh Air (Oxygen). First harvest of Mushrooms will occur within 1 week.

Yummy Stage - Harvesting

You can harvest the mushroom when you see the gills of the Mushroom (when the veil breaks from the stem), this is perfect to in terms of ripeness. As always, the best method is to pull and twist when harvesting, as this leaves a clean break from the Mycelium.

Renew/Flushing Stage - Crop Cycle

5. With clean water submerge the wooden block for 3 to 5 hours, weight it down if necessary. This will re-hydrate the wooden substrate material and provide the mycelium with much needed moisture. Place the mycelium block back into a clean bag and close off to simulate underground conditions, this will allow the mycelium time to regenerate. Watch for pin formation and carefully monitor for signs of contamination.
