Blue Oyster Grain Spawn – 3.5lbs

The Blue Oyster mushroom variety stands as the most prolific strain, delivering abundant yields of remarkable mushroom clusters. These clusters grow impressively large, showcasing impeccable mushrooms. In their youthful stage, the mushrooms exhibit a vibrant blue hue, which gradually transitions into a graceful grey-brown shade as they mature, depending on the lighting conditions.

Recommended use:

• Blue Oyster grain spawn can be used for indoor production using sawdust-based sterile substrate.
• Do not use grain spawn for log inoculation.
• This is not a mushroom grow kit. Blue Oyster grain spawn must be combined with a substrate in order to fruit.
• If you don’t plan to use immediately, you can refrigerate your spawn for up to 4 months.
