Beginners Favorite

This is an easy species to grow and fruit, ideal for people who are just starting out.

This isolation is the Hungarian variation of the standard tree oyster mushroom. This spectacular strain is fast and flat out the most productive PO species we've tested. A wide range in fruiting temperatures and its aggressiveness make it a great choice for pasteurized substrates. Clusters should be picked early and handled carefully, or quality may suffer. Densely clustered fragile caps require gentle handling.


Our PoHu Oyster Mushroom Grain Spawn is grown on 100% certified organic rye berries. It arrives contaminate free, fully developed, and ready to use. PoHu Oyster Mushroom Grain Spawn is used to inoculate many bags of bulk substrate quickly. Transferring grain into bulk substrate bags is the choice methodology for medium and large scale growers. PoHu Oyster Mushroom Grain transfers are usually performed in a flow-hood or bio-cabinet. Simply break up the PoHu Oyster Mushroom Grain Spawn, then transfer grains to each bag you want to inoculate.
