Editorial standards

MushroomGuide.ca is written and edited by the MushroomGuide.ca Editorial Team, operated from Ontario, Canada as part of the GrowersGuide brand family. This page explains how we make our content and how we keep it trustworthy.

Experience first

We grow gourmet mushrooms ourselves — oyster, lion's mane, king oyster, shiitake, and chestnut — in Canadian basements, garages, and grow tents. The methods, timings, and yields we publish come from grows we've actually run, not just summarised from elsewhere. The tools and kits we recommend are ones we've used or researched in depth.

How we source facts

Every specific figure on this site traces back to a primary source:

• Nutrition data — the Canadian Nutrient File and USDA FoodData Central, presented as factual data, never as a health benefit.
• Climate & growing conditions — Environment and Climate Change Canada climate normals (1991–2020) and established mycology references.
• Any research claim — peer-reviewed studies indexed on PubMed/NCBI, cited inline.

What we write about — and what we don't

We cover four things: how to grow, when to harvest, how to cook, and what's safe for pets. Cultivation, taste, technique, and recipes — that's the whole site.

We are not a health or wellness site. We do not publish medicinal or "traditional use" content, supplement guidance, or "good for you" claims of any kind. We also never cover psilocybin or wild-mushroom foraging and identification — see those policy pages for why.

Review & fact-checking

Every post is reviewed before publishing for accuracy, for safety (spore handling, sterilisation, pet toxicity), and for compliance with the policies above. Posts carry a publish date, and we add a "last updated" date whenever we revise the substance of a guide.

Corrections

If you spot an error or an out-of-date figure, email info@mushroomguide.ca. We correct confirmed mistakes promptly and update the "last updated" date.

Independence & affiliates

Some links on this site are affiliate links, and we may earn a commission on qualifying purchases at no extra cost to you — see our affiliate disclosure. Affiliate relationships never determine our recommendations or our verdicts. We do not sell our own mushroom products.
