Organic Grey Oyster Fruiting Block – 5 lb Mushroom Growing Kit

A fully colonised, USDA certified organic 5 lb fruiting block of grey oyster mushroom (Pleurotus ostreatus), producing pearl-grey caps. No mixing or preparation is needed: open the bag and mist once or twice daily. The block fruits under indirect or standard room lighting in the cool, humid conditions of a typical Pacific Northwest home. Held at consistent humidity it produces multiple flushes, with the first usually within days.
