Our most popular Mushroom Patch! Composed of a unique blend of sterilized, enriched sawdust fully colonized with a select strain of Shiitake (Lentinula edodes). Esteemed for both its health-supporting properties and its culinary value, our newest generation of Shiitake kits are super-boosted to give the most prolific harvests yet. Shiitake mushrooms can be harvested at 2 week intervals for up to 16 weeks. A 50-80° F environment is ideal.
