After you have harvested the mushrooms simply continue misting daily and within 3 weeks you should get an additional flush of mushrooms. If at any point the block seems really dry you can soak it in a large pot of cold tap water overnight to rehydrate it. You can get 2 - 4 flushes of mushrooms from this block. *You probably will not need to soak between the first and second flush of mushrooms. After the second flush try soaking for no longer than 8-hours.
