Mushroom plug spawn is spiral-grooved hardwood dowels infused (inoculated) with a specific mushroom species, in this case shiitake mushroom (Lentinula edodes). The mushroom mycelium (the white, root-like network of cells) colonizes and penetrates the dowels as it consumes the lignins provided by the wood. These plugs are used to inoculate freshly cut hardwood logs, stumps, or rounds to create a fruiting mushroom colony that can produce mushrooms for many years! These colonies are commonly referred to as mushroom logs. After waiting approximately one year from inoculation, a well cared for log will produce mushrooms several times a year, for 3-5 years. Shiitake logs are fun to make, require little maintenance, and will reliably produce mushrooms for years! Inoculate your own prepared logs using our 5/16in x 1in spiral grooved colonized plug spawn. A pack of 100 plugs is sufficient spawn to successfully inoculate 3-4 mushroom logs. Keep refrigerated until ready to use, for up to two months.
