Our goal is simple: every guide on TrayGrown should help you grow a better tray, with information you can trust. This page explains how we work.
How we choose topics
We write about the questions indoor growers actually ask — especially the problems that stop people from succeeding, such as mold, poor germination and leggy seedlings. Each guide aims to answer one question fully, rather than covering many topics thinly.
How we research
We base our guides on:
- university and government agricultural extension publications;
- horticultural research on seedlings, light and plant disease;
- growing data published by established seed and microgreen suppliers;
- consistent, widely reported practical experience from the growing community.
Where sources disagree — seed rates and harvest days vary a lot — we give a range and explain what affects it, rather than a single number that won’t fit everyone.
How we write
- Practical first: steps, numbers and tables you can use straight away.
- Plain language, with technical terms explained.
- Honest about limits: we say when something is uncertain or varies.
- No health claims: we don’t make medical or nutrition promises about microgreens.
We use modern research and writing tools, including AI-assisted drafting, to help organize and draft content. Every guide is reviewed, edited and fact-checked by a person before publishing, and we take full responsibility for what we publish.
Updates and corrections
We review guides regularly and update them when better information becomes available. Pages show the date they were last updated. If you spot an error, please contact us — we correct factual mistakes promptly.
Independence and advertising
TrayGrown is funded by display advertising. Advertisers have no influence over what we write, and ads are clearly separated from editorial content. We don’t accept payment for reviews or rankings. If we ever use affiliate links, we will disclose them clearly.
