Mycelium on organic Maïtake grains

Grifola frondosa, Tufted Polypore, Hen of the Woods

Maitake, Grifola frondosa, is not only a good edible mushroom, but also an excellent medicinal mushroom used for centuries in traditional Chinese and Japanese medicines.

The active ingredients particularly sought after in maitake are D-Frcation and MD-fraction derived from complex sugars of the beta-glucan type which can be found in this mushroom. These components are particularly studied for their immunostimulating and anti-tumor properties. (1,2), reduction of diabetes (3) and hypertension (4).

Its cultivation is generally done indoors on substrates based on sterilized enriched sawdust, or outdoors on wooden logs inoculated with dowels. His favorite species are chestnuts and oaks.

Please note that the fruiting of this mushroom is relatively more complex than most other cultivated mushrooms and is therefore more intended for experienced mushroom growers.

Growing conditions

Maitake prefer cool temperatures of 10 to 15-18°. They need constant high humidity at the beginning of fruiting, which gradually decreases until harvest.

Indoor cultivation: pasteurized/sterilized enriched sawdust. We recommend our ready-to-use substrate , particularly suitable for wood-eating varieties.

Outdoor cultivation: Wooden logs (chestnut trees, oaks) semi or completely buried.
