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.
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.

Species name: Pleurotus ostreatus
This variety forms dense, uniform clusters of chocolate coloured oyster mushrooms. They are great for commercial growers as yields are consistent and heavy due to the Chocolate Oyster's dense cluster formation. Pick early when caps are still curled and dark as these little heavy clusters are great for retail punnets.
Chocolate Oysters prefer colder conditions. You will grow deep brown caps and more dense clusters in cooler temperatures. If grown at the warmer end of their range, colour will be lighter.
The Chocolate Oyster is our favourite Oyster variety to eat, we find it has the best flavour and texture of all the Oyster varieties we grow and is quickly becoming a chef favourite as well.
Chocolate 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 period: 14 - 21 days (depends on substrate). Average incubation period is 14 days on Masters' Mix.
Incubation temperature: Room temperature between 21 - 24°C. Do not let the substrate temperature exceed 30 °C.

Pinning humidity: 95 - 100% relative humidity

Range: 10 - 21°C
