The "Espresso Oyster" Mushroom Growing Kit

With the Espresso Oyster mushroom growing kit you can 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. Each mushroom growing kit comes complete with 1 gallon of Pearl Oyster Sawdust Spawn and detailed instructions. Every mushroom grow kit is certified organic.
