Growing details

SPECIES DESCRIPTION

Species name: Pleurotus eryngii 

There are many common names for this widely cultivated species - King Oyster, King Trumpet, King Brown...but always King. King Oysters are regarded as one of the best tasting of all gourmet mushroom species and are our personal favourite to cook with. Popular with chefs and home cooks alike, these are a staple in the commercial growers' repertoire.

They require cooler temperatures under 21°C and high humidity to set pins. More environmental controls are needed to grow this strain consistently.

PREFERRED SUBSTRATE

King Oysters grow best on hardwood substrates. They can be grown on a straw/sawdust mix but yields will be small.

For highest yields and fast colonisation grow on Masters' Mix.

INCUBATION

Incubation period: 21 days (depends on substrate).

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

PINNING CONDITIONS

Pinning temperature: 10 - 15°C 

Pinning humidity: 95 - 100% relative humidity

FRUITING CONDITIONS

Fruiting temperature:

Range: 15 - 21°C
Ideal:
15 - 17°C

Fruiting humidity: 85 - 90% relative humidity

CO2 concentration: 500 - 2000 ppm. Low levels of CO2 will form larger caps and shorter stems. If growing for large stems, increase CO2 levels.

Important note: these growing guidelines are drawn from our years of experience as commercial mushroom growers. They are a guide only. We encourage experimentation to discover what works best for your individual conditions.
