From the brand

After an intense spiritual healing journey in 2021 we decided we wanted to help others find their path too. We believe in the healing powers of mushrooms so we started on a mission to make the process of growing at home as easy as possible. Our products make growing mushrooms accessible for everyone from beginner to seasoned veteran. Whether you want the ease of an all in one bag or a great deal on bulk spawn and substrate we have what you need.
