Summary
McKennaii Mushrooms is published by the team behind Dutch-Smart, a smartshop in the Netherlands. Dutch-Smart sells McKennaii grow kits, and the product links on this site go to that shop. When you buy through such a link, we earn from the sale.
We say this first because it matters for how you read the rest. The site exists because most of what is online about McKennaii is shop copy or repeated rumour. We wanted one place that handles a single cultivar the way a reference work would: with sources, with dates, and with a clear line between what is measured and what is said. That includes the parts that do not help sales, such as the absence of any lab data on McKennaii's strength and the fact that the mushrooms are illegal in the Netherlands.
How the pages are made
- Facts about the species, its chemistry and its genetics come from peer-reviewed studies and public data records, linked in each page's reference list.
- Legal statements come from the text of the law or from public bodies such as the Trimbos Institute and the Public Prosecution Service, with the date we checked them.
- Where we rely on a shop's own guidance or on a magazine interview, the text says so.
- Claims we could not verify, including both origin stories of the name, are reported as unverified or left out.
- We make no medical or health claims of any kind, and publish no testimonials or reviews.
Every page shows when it was last updated. Laws, products and research change; if something here is out of date or wrong, Dutch-Smart's customer service can pass it on to us.
Who is behind the shop
Dutch-Smart is a Dutch smartshop that ships from the Netherlands and sells only to adults. The illustration of mushrooms used on this site was generated for it and is labelled as such; it does not show a McKennaii specimen.
