Our USDA-certified organic Snow Oyster (Pleurotus ostreatus) grain spawn features a popular strain that produces firm caps with a sweet flavor and aroma that holds its shape when cooked. The taste of snow oyster mushrooms is very mild, and some even describe it as slightly woody and earthy. Snow oysters are great for confident beginners and are reliable indoor year-round producers. If kept in the right conditions, they will yield substantial first, second, and even third harvests (making them an ideal commercial variety!)

Snow oyster grain spawn can be used for indoor cultivation year round. When used for outdoor cultivation, snow oysters will fruit in the cooler months.

Recommended use:

• Snow oyster grain spawn can be used for indoor production using sawdust or straw or outdoor production using straw or wood chips.
• Do not use grain spawn for log inoculation.
• This is not a mushroom grow kit. Snow oyster grain spawn must be combined with a substrate in order to fruit. 

Upon receiving your spawn:

Remove it from the shipping box as soon as possible. Then, unfold the top of the bag, making room for air space. It's also important to check and confirm that the filter patch is not obstructed. This will help the organism breathe and continue to thrive!
