About

About

Sprout & Fin is a free course on how plants grow without soil, for anyone aged 8 and up.

Why it exists

Hydroponics and aquaponics are mostly taught through scattered videos, forum threads, and thick books. Beginners and teachers have no clear place to start. Sprout & Fin is that place: short lessons, something to try in each one, and facts you can trust.

It is an independent, non-commercial project. There are no ads, no accounts, no paid tier, and no product recommendations.

How the lessons are checked

  • Every fact is checked against published references, such as university extension guides and the Food and Agriculture Organization of the United Nations.
  • Where good sources disagree, the lesson gives the range and says so.
  • Every lesson lists its sources. See all sources.
  • Mistakes are fixed in public. See the corrections log.

Reuse

The lessons are released under CC BY-NC 4.0. Schools and nonprofits are welcome to reuse them with credit.
