Any hardwood loving mushrooms can be grown on straw, wood chips or sawdust blocks, including Shiitake, Oysters, Reishi, and Lion s Mane. Mushroom cultivation involves first "inoculating" the substrate of your choice with mushroom mycelium, and then allowing the mycelium to colonize over a period of 2-3 weeks. When the substrate is fully colonized- and the conditions, such as light, moisture, and temperature, are right- the mushrooms will emerge from the substreate and can be harvested and enjoyed.
