After trimming, the stumps are stored in a shady place in a vertically position in anticipation of use, which usually occurs from April to June.

30 cm segments are cut off from the trunks, pits are pulled out 1 meter wide and 120 cm deep. A layer of mushroom mycelium is placed on the bottom of the pit, and vertically located trunks are placed on top. Then another layer of mycelium and the trunk and so on. The upper part is covered with boards and poured a soil layer 15 cm.

The warmth and humidity that form inside the pit will facilitate the distribution of mycelium through the logs laid inside.

As soon as the mycelium penetrates the full bag with the substrate, remove the plastic and place the bag on the shelf in a sunny or artificially lit place and maintain a temperature of about 15 ° C.
