Organic Maitake - Grifola frondosa - Sawdust-Spawn
Synonyms: Hen of the Woods, Ram's Head, Sheep's Head, Signorina mushroom, Maitake, Kumotake, Huai Su Gu
The Maitake is considered a particular marvel in Asia, already centuries ago. This was due in part to its unusual bush-like shape, which allowed the mushroom to adapt exceptionally well to its surroundings. providing excellent camouflage. Additionally, it was considered so valuable (because of its properties) that its locations were kept strictly secret by collectors. Today, the Maitake is known in both Asian and European-American regions as a delicious, meaty edible mushroom, distinguished by its high nutritional value. Because of this, it has garnered significant interest in the pharma industry, and has been a valuable research subject in Korean, Japanese and American studies for several years.The fruit bodies have a brownish to dark grey color, many overlapping caps sprout from each mushroom stalk, with diameters ranging 2 - 10cm. The young fruit bodies are particularly delicate in flavor. Fully matured Maitake can be dried and prepared as tea. Under particularly favorable conditions, Grifola frondosa fruit bodies can weigh 500g or more.
Sawdust spawn is always made fresh on demand. Production time: 3 - 6 weeks.
This product is fresh produce and should be processed immediately after delivery.

Suitable cultivation methods:
wood logs,
spawn bags for indoor greenhouses
Suitable substrate: hardwood
Suitable woods: maple, birch, beech, oak, alder, aspen, poplar, elm and willow
Outdoors: this strain produces fruiting bodies in late summer and early autumn
You receive fully colonised sawdust spawn based on organic raw materials (wood, rye bran from organic cultivation) in bags specifically suitable for sterilisation.
Information for cultivation on straw and substrate:
1 autoclave bag with app. 3 litres of mushroom spawn is suitable for inoculating 1 straw bale or 5 - 15 substrate bags
1 autoclave bag with app. 6 litres of mushroom spawn is suitable for inoculating 2 straw bales or 10 - 30 substrate bags.
Information for cultivation on wood:
When using our equipment ( inoculation stick or hand inoculator ) the sawdust spawn bags are suitable for:
1 autoclave bag with app. 3 litres of mushroom spawn is suitable for inoculating 12 - 15 linear metres of wood
1 autoclave bag with app. 6 litres of mushroom spawn is suitable for inoculating 25 - 30 linear metres of wood.
For quantities of 10 logs or more, inoculating with sawdust spawn ins usually more efficient than working with dowel spawn. The rwa materials sawdust and wood chips are by-products and therefore more cost effective and sustainable than specially manufactured wooden dowels. As a result, sawdust spawn can also be produced cost-effectively in large quantities. Sawdust spawn is suitable for the drilling method and the cut inoculation method.
The expected yield is up to 10% of the fresh wood weight, divided into several harvest waves over a period of 3 - 5 years.
When utilising the drilling method we recommend using a mushroom drill and an inoculation stick or a hand inoculator.
Suitable for beginners.
Large quantities for commercial mushroom cultivation available upon request.
