King Oyster Grain Spawn

Our grain spawn is grown on 100% certified organic rye berries. It arrives contaminate free, fully developed, and ready to use. Grain spawn is used to inoculate many bags of bulk substrate quickly, and is the choice methodology for medium and large scale growers. Simply break up the grain spawn well, then transfer some grains to each bag you want to inoculate. 

King Oyster Mushroom

P. eryngii is the largest species in the oyster mushroom. It has a thick, meaty white stem and a small tan cap (in young specimens). Its natural range extends from the Atlantic Ocean through the Mediterranean Basin and Central Europe into Western Asia and India. Unlike other species of Pleurotus, which are primarily wood-decay fungi, the P. eryngii complex are also weak parasites on the roots of herbaceous plants, although they may also be cultured on organic wastes.
