Cultivation of the Agaricus (white or crimini) mushroom consists of six steps: Phase I composting, Phase II composting (Pasteurization), Spawning, Casing, Pinning, and Cropping. These steps are described in their naturally occurring sequence. Of course, there are other related activities necessary to support these basic steps. Overall, it takes approximately 9 weeks to complete an entire growing cycle from filling the room to the final clean up after harvesting has ended. The composting process on the wharf takes about 3 weeks prior to filling the room.
