It is made up of special soil with the shroom spores, and all I have to do is spray water to keep it moist and cover with some plastic to keep the humidity in. They say to use the bag the log came in for that. So that is what I am doing. The fun is watching them grow. They get fairly big before you harvest them. Will post progress pics as they grow.
I had a choice of crimini, shataki, oyster or maitaki mushrooms. If this does well I may try others.
