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.  


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 name: Grifola frondosa

The Maitake Mushroom, also known as Hen of the Woods, is one of the best tasting mushrooms in the cultivated mushroom world. Native to Japan, Maitake translates to "dancing mushroom" because it is so prized in Japanese culture that people would dance with excitement when they found it in the forest. This mushroom is more challenging to grow and we recommend it for advanced cultivators. If you can master the Maitake you will be rewarded with a delicious meal. Maitake are full of flavour and have a firm texture, they store very well in the fridge once harvested. 


Maitake prefer hardwood sawdust.

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


Maitake need to be incubated in different phases.

Phase 1: The initial incubation phase is similar to other species. Over 3 - 4 weeks the substrate will colonise with white mycelium. Once the block is fully covered in a solid mat of mycelium the block is ready for Phase 2.

Phase 2: From this stage onwards the block should be kept in constant light. A white LED light is fine for this purpose. During week 4 - 6 dark pin formations will start to form on the top surface of the block. The light will increase the colouration and direction of these pin sets. Once the pin formation is about the size of a small fist the block is ready to be moved into the fruiting room.

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


Pinning temperature: 18 - 21°C 

Pinning humidity: 95 - 100% relative humidity

Let the Maitake pin set form inside the closed bag during Phase 2 of the incubation cycle. Trying to get Maitake to pin in a fruiting room with other species present can be difficult.


Fruiting temperature:

Range: 18 - 27°C
18 - 19°C

Fruiting humidity: 90 - 95% relative humidity

CO2 concentration: 500 - 800 ppm
