Awesome informative manual. A lot of hints and hands-on experience. Basically, this might be the only book or manual required to get started. Probably might want to read some of the original works by McKenna brothers or Paul Stamets, but those to understand the theory a little in more depths. I assume this manual can be used for any type of grower, whether it's usual mushrooms, medicinal (like Lion's Mane) or psychedelic, it should not differ much except some species-related nuances like humidity, temperature or substrate type, the technique stays the same.
