WHOLESALE SUPPLY

Are you a mushroom grower looking for a regular supply of commercial quantities of high quality grain spawn?

We have bulk rates for commercial customers. Visit our Wholesale page for more information and to apply for an account.

SHIPPING & DELIVERY

Mycelium is extremely sensitive to temperature changes and transport conditions.

And mushroom grain spawn is alive with mushroom mycelium. That’s why we strongly recommend shipping grain spawn via Express Post.  

Dispatch

We ship orders Monday to Thursday. We do not dispatch grain spawn on Fridays to avoid it being in transit over weekends due to its heat sensitve nature. Any orders placed on Thursday after 12pm or Friday will be dispatched the following Monday.

Please note this applies to all orders, including Express Post shipments.

Growing details

SPECIES DESCRIPTION

Species name: Pleurotus ostreatus var. Blue Pearl 

This strain forms heavy, dense clusters of beautiful pearlescent blue mushrooms. They are great for commercial growers as yields are big and the caps are thick and robust, standing up to some handling.

The mycelium is vigorous, making it more forgiving for first-time growers but it does prefer colder conditions so grow seasonally if you don't have the ability to control your growing temperature. You will grow darker blue caps and more dense clusters in cooler temperatures. If grown at the warmer end of their range, colour will be steely blue-grey. Pick at immature-adolescent stage to avoid colour fade.

PREFERRED SUBSTRATE

Blue Oysters 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: 10 - 21 days (depends on substrate). Average incubation period is 14 days.

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

PINNING CONDITIONS

Pinning temperature: 10 - 18°C 

Pinning humidity: 90 - 95% relative humidity

FRUITING CONDITIONS

Fruiting temperature:

Range: 10 - 21°C
Ideal:
15 - 17°C

Fruiting humidity: 85 - 90% relative humidity
