Our USDA-certified golden oyster (Pleurotus citrinopileatus) grain spawn feature a tropical strain that produces beautiful clusters of bright, jaw-droppingly beautiful mushrooms with medium yellow caps and long delicate stems. A favorite at farmer's markets, they have a mild nutty flavor and aroma reminiscent of cashews. Golden oysters are great for 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!) As a tropical strain, they thrive with higher humidity.

Golden oyster grain spawn can be used for indoor cultivation year round. When used for outdoor cultivation, golden oysters are generally not cold tolerant and fruit prolifically in summer months. 

Recommended use:

• Golden 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. Golden 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!
