Unused log wood for shiitake mushrooms. Quercus serrata (Japanese oak) These are from the logs produced when felling shiitake mushroom logs from my own mountain forest, and have been cut to a size that doesn't take up much space. ★Easy-to-cultivate size for home use★ ☆These are log woods without mushroom spawn (komagoma) planted☆ ★Because they are fine-grained, the mycelium will spread relatively quickly, and shiitake mushrooms can be harvested sooner★ ☆For those who want to cultivate shiitake mushrooms, those who want to try it themselves, and various other uses☆ 【Size】 Diameter: Approximately 5cm Length: Approximately 50cm *Please note that there may be slight variations due to amateur measurements. 【Drying】 Naturally dried for over a month after felling.
