Hi - Our son, for Christmas, had two logs about 12"-14" long, shipped to us from a mushroom growing place. They are Shiitake mushrooms. Well, after following all the directions, we finally have shiitake mushrooms coming out of these two logs. It's quite a hoot watching how quickly they grow day by day. Has anyone else tried doing this and, if so, how well did it work for you? I looked at them in the produce dept. at our grocery store and, wow, they are super expensive, like around $3.00 an ounce :!: Well, would like to hear from any of you on this topic.
