North Spore is discontinuing its Organic Golden Oyster Mushroom Plug Spawn for outdoor cultivation. This decision reflects our commitment to responsible mycology practices and environmental stewardship.

The discontinuation is in response to growing concerns regarding the naturalization potential of Pleurotus citrinopileatus, the scientific name for Golden Oyster mushrooms, when grown in outdoor environments.

As a company founded by mycologists with a focus on sustainable agriculture, North Spore prioritizes ecological balance and quality products. Our USDA Certified Organic standards apply to our remaining stock.

This plug spawn provides an opportunity for experienced growers to utilize high-quality mycelium before it is no longer offered. It is engineered for robust growth in suitable substrates.

For those interested in cultivating this species, we encourage purchasing any remaining Organic Golden Oyster Mushroom Plug Spawn promptly, as supplies are limited.
