Mushroom cultivation with coffee grounds and spent grain will create a circular economy for small-scale and urban farmers. In pursuit of a no-waste system of food production, mushroom cultivation also provides soil amendment opportunities with composting after harvesting. 3 Flock Farm sought to determine the highest yield method of mushrooms from spent grain or coffee grounds.
The following resources from the Three Flock Farm have been created in connection with this research:
