As awareness has grown about the potential of psychedelic mushrooms to aid in the treatment of depression, addiction, and PTSD, interest in psilocybin mushrooms has soared. Thanks in part to books like Michael Pollan's How to Change Your Mind , public opinion is shifting, and "psychedelic-assisted therapy" courses are cropping up like a bumper crop of mushrooms. Changes in legislation are starting to catch up to changing attitudes. With the passage of ballot Initiative 81 (the Entheogenic Plant and Fungus Policy Act) in November 2020, Washington, D.C. joined Denver, CO, Oakland, CA, Santa Cruz, CA, and Ann Arbor, MI, on the list of cities where the use of psilocybin mushrooms has been decriminalized. As this list grows, the number of people interested in cultivating their own psilocybin mushrooms is expanding too. This practical, informative guide to psilocybin cultivation takes you through the mushroom life cycle, offering simple and concise instructions for germinating and growing indoor species of mushrooms as well as outdoor species that fruit on wood chips.

Color photographs and hand-drawn illustrations convey every step of the cultivation process, enabling any cultivator to identify mushroom species, parts, and ripeness, as well as troubleshoot common problems. Over 25,000 copies of Psilocybin Mushroom Handbook have sold since the book's publication, and this easy-to-read handbook continues to be a must-have for anyone interested in learning the methods of psilocybin cultivation.
