Reishi (Ganoderma lucidum) is the easiest of all our fruiting block kits. Not only is it a very reliable producer, but it requires almost no upkeep! (That's because reishi can live their entire life cycle within an unopened bag.) Reishi is an edible medicinal mushroom known as “Ling Zhi” in China and “Reishi" or "Manetake” in Japan. And our reishi fruiting block features a hearty strain that is widely cultivated in Asia and beloved by growers.
