Organic Italian Oyster Mushroom Grain Spawn

Our USDA-certified organic Italian oyster (Pleurotus pulmonarius) grain spawn features a strain with a deliciously mild flavor and earthy aroma. Italian oyster mushrooms are thicker and meatier than blue oyster mushrooms, and their brown frilled caps can grow quite large. They 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!)

Italian oyster grain spawn can be used for indoor cultivation year round. When used for outdoor cultivation, Italian oysters are generally cold tolerant and fruit prolifically in early spring or late fall.

Recommended use:

• Italian 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. Italian 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!
