How To Grow Mushrooms

Editorial policy

How How To Grow Mushrooms decides what to publish, what it will not cover, how guides are reviewed and where commercial interests stop.

Our standard

Guides answer the question first, then give the detail. We write for people growing at home, and we say plainly when a species is demanding or when a method often fails. Conditions are given as temperatures, humidity and timings tied to a named source, not vague advice.

What we cover, and what we don’t

  • Cultivation of legal culinary (gourmet) species and medicinal-cultivation species only. Oyster, lion’s mane, shiitake, king oyster, wine cap, reishi and similar species that people grow at home.
  • Nothing about psilocybin or any other psychoactive mushroom.
  • No wild-mushroom identification and no foraging advice. We will not tell you whether a mushroom you found is what you think it is, or whether it is safe to eat. Morels and chanterelles appear only to explain why they are hard to cultivate.
  • No health or medical claims. For medicinal species such as reishi, turkey tail and cordyceps we cover how they are grown, and nothing about what they might do for the body. For medical questions, ask a qualified professional.

Pen name

Articles are published under the editorial pen name Wren Holloway. The name is disclosed on the about page and in the structured data of every page. We do not give it credentials, employers or experience it does not have.

Sources

Claims about temperature, humidity, colonization and fruiting times, substrates and contamination come from university extension services, government and research publications, and spawn-supplier information. Each guide lists its sources at the bottom.

Images

Photos carry a visible credit. Where no accurate free photo exists we may use an AI-generated image, checked for species accuracy before use and listed on our image credits page.

Commercial relationships

Nobody pays to change a recommendation. If we ever publish sponsored content, it will be clearly labelled as sponsored.

Updates and errors

Guides show a last-updated date. If we get something wrong, we fix it and say so: see corrections.
