The Warm Blue Oyster – (Pleurotus ostreatus)

Previous slide

The warm blue oyster is one of our most prolific indoor commercial fruiting strains with an extremely WIDE fruiting temperature window. Meaty and sweet, this mushroom is also known for its antiviral properties as well as cholesterol lowering abilities. Optimum fruiting occurs when temperatures between 50-80F, but it can produce as high as 95F. Outdoors it fruits well on oak, sweetgum, poplar, and many other hardwood species. Indoors we recommend fruiting this strain on pasteurized wheat straw and cotton hulls for incredible yields. We grow this strain year-round indoors and it forms beautiful, thick clusters. The blue color will fade into a light steel-blue, grey color. Like all oysters, these mushrooms are high in protein and wonderful sautéed, grilled, or fried as a side or even the main course!
