Start with the tray
Every variety guide starts from how the crop is grown: how much seed fills a tray, whether to soak it, how many days it spends covered, and when it is ready to cut. We present those essentials on a seeding card at the top of the guide, with the source named underneath.
Where the facts come from
- University extension publications and government or research-institute papers
- USDA Agricultural Research Service measurements of microgreen nutrient content
- Peer-reviewed studies, cited by title and year
- Grower reports, treated as reports of experience rather than proof
When sources give different figures we show the range and say which sources they come from. Sources are listed at the end of each guide.
Only what is sourced
If a figure has no source, such as the soak time for a particular variety, the seeding card leaves it out. We don’t fill gaps with a plausible number. Nutrient panels appear only where a named study measured the variety.
Review before publishing
Each guide is read for accuracy, clarity and unsupported claims before it goes live, and revisited when new information changes the advice.
What we don’t claim
We don’t invent statistics or personal growing histories. If we have not grown a variety ourselves we do not write as if we had. We stay within the limits in our editorial policy: home growing and sourced nutrient facts, with no medical or health claims.
