Pholiota Adiposa, also known as Chestnuts, is a species of the pholiota family. Probably one of the most aesthetically pleasing mushrooms to cultivate, it grows in clusters ranging from 3 to 12 cm. The caps evolve from dark brown at the beginning of growth to a light orange at maturity, with edges adorned with small white fuzz. Its cultivation is similar to that of naméko, but without the slimy texture. The stems of the chestnuts remain crunchy when cooked, offering a delicate flavor.
Mycelium storage: 1 month in the refrigerator.

Our commitment to quality:

We produce our mycelia in laboratory conditions, which guarantees the purity of the varieties and optimal quality.

We produce our myceliums in a 100% organic way and all our products are certified "BE-BIO-01, Agriculture Belgium" by CERTISYS.

🌱 Growing conditions
Like namekos, chestnuts prefer cool temperatures of 10 to 15°C. They require constant high humidity. For better conservation, it is advisable to harvest young mushrooms, just before the caps open. After the first harvest in "top fruiting", the plastics can be removed and the bales must be watered regularly in "rain".
🛠️ Substrates
Chestnuts are grown on pasteurized sawdust in indoor cultivation, or on logs in outdoor cultivation.
We recommend our ready-to-use substrate , particularly suitable for wood-eating varieties.
