Blue Oyster Mushroom Cultivation
Pleurotus ostreatus: A fast substrate colonizer with a strong blue/gray hue.
Blue Oyster spawn comes in three distinct styles:
Plug Spawn - Great for first time mushroom log growers. Used for small projects. 1-10 logs.
Sawdust Spawn - Used for larger mushroom log projects, or by those wanting to inoculate logs every year. Used for small to large enthusiast or commercial projects. Best for inoculating 10 or more logs. *You need an Inoculation Tool to use Sawdust Spawn! For larger projects you may want to purchase an Angle Grinder Adapter and specialized 12mm drill bit!
Grain Spawn - This is used for outdoor straw or wood-chip beds or commercial indoor production using sawdust or straw. You do not use grain spawn for log inoculation.
On Logs - Use Sawdust or Plug spawn for log cultivation. Blue Oyster works well with the Log, Stump, and Totem methods. Colonization is fast and may start producing in 4-12 months, though fruitation is dependent on environmental triggers. They fruit best in the spring and fall and prefer softer hardwoods such as poplar and aspen. They will also work on maple.

Outdoor Beds - With Oyster mushrooms you may also choose to use grain spawn to inoculate outdoor straw beds. We've had success growing Blue Oyster mushrooms in our raised garden beds by sprinkling grain spawn in the beds in the spring. We had Blue Oysters growing right out of our soil!
Indoor Commercial Production - Oyster mushroom grain spawn can be mixed into sterilized or lime pasteurized substrates including but not limited to hardwood sawdust, straw, and coffee grounds. These processes range from requiring a fair amount of infrastructure for larger projects to simple and low-tech. We recommend purchasing a book on mushroom cultivation if you are interested in pursuing this style of mushroom production as a hobby or profession. We recommend 'Radical Mycology: A Treatise on Seeing and Working with Fungi' by Peter McCoy, 'Organic Mushroom Farming and Mycoremediation' by Tradd Cotter, or 'Growing Gourmet and Medicinal Mushrooms' by Paul Stamets.

Oyster mushrooms are a great mushroom for beginners. They colonize quickly and are reliable producers. Great for commercial cultivation, especially grown on straw.
Cooking: Blue Oysters can easily replace button mushrooms in most recipes and pair well with many cuisines and flavors. Like all Oyster Mushrooms, they retain water and may develop a viscous texture when under-cooked. If you prefer a firm or dryer texture, continue to cook Oysters until their liquid has reduced and cooked off and they begin to brown.
Properties: The Blue Oyster mushroom has a high protein content, several B vitamins, and all the essential amino acids (Marley, 2009). Its medicinal benefits include promoting anti-tumor activity and lowering high cholesterol. Oyster mushroom fruiting bodies and distillations have been shown to reduce tumor size in several studies on mice, rats, and hamsters (Hobbs, 1995). Additionally, Oyster mushrooms have been used in the Czech Republic as the main ingredient in a dietary supplement used to treat high cholesterol (Hobbs, 1995). Studies in animals have shown that a diet of Oyster mushrooms reduced the development of plaque in major arteries (Bobek et al., 1995).
