About the Mushroom

Red Boy is one of the PF (Psilocybe Fanaticus) original strains.

Their red spores have earned them a special place in the heart of the mushroom growers’ community.

If you want to see the full range of their beauty, leave them standing until the first mushroom opens its gills. Then harvest them quickly, to ensure that they stay as potent as possible.

Take that mushroom that has opened its gills, remove the stem and carefully place it gills-down on a piece of white paper.

By the next day, you can carefully remove the mushroom and you will have an amazing looking red spore print on the paper.


About the species

Psilocybe Cubensis is actually the easiest to grow of all mushrooms, including culinary or medicinal mushrooms.

Likely, people have cultivated theses mushrooms for millenia, spreading them around the world. That’s why there are so many “strains” that are variations of this one kind of Magic Mushroom.

Most cultivated mushrooms on the market are of the Psilocybe Cubensis variety.
