We absolutely love mushrooms! There are a couple of 'root cellars' that are in such disrepair that mushrooms might be just the ticket. Thanks!!! Will look into that.You can also use fresh coffee grinds to grow your own mushrooms if you like them! (Due to the temperature of the water, you are essentially sterilizing the coffee grinds when you make coffee, so the fresh grinds are great for mushroom culture.)
