Roots in water

A video by Nicolas Brewitzer, Mariia Brewitzer & Paul Feldmann

Aqua- and Hydroponics in Action

This video project was conducted for the module Science Communication and presents an example of innovative sustainable technology: Aqua- and Hydroponics, which involves growing plants in a closed-loop system using nutrient-enriched water.

The topics covered include general information about aqua- and hydroponics, the advantages of different systems, various substrates used for plant growth, their use as sustainable examples, and the potential and future possibilities of these systems.

Special thanks go to TERRA Urbana Umlandentwicklungsgesellschaft mbH and Universität Rostock for providing filming locations and resources.

To ensure scientific accuracy, this project was based on the research paper: https://doi.org/10.1038/s41598-024-68361-3
