Practice bioremediation at home! Recycle old newspapers, coffee and espresso grounds by inoculating them with Oyster Mushrooms (Pleurotus ostreatus). One of our favorite methods is the simplest: just mix the sawdust spawn directly into coffee grounds, espresso or perked. Our Pearl Oyster spawn fruits in a wide temperature range, making it suitable for inoculation across the country. A fascinating project for people of all ages. Kit comes complete with 1 gallon of Pearl Oyster Sawdust Spawn and detailed instructions.
