The project „Greenhub - Nährstofferfassung und Entwicklung einer systemspezifischen Nährstofflösung und eines Mikro-Aquaponik-Mehrkreislaufsystems“ is funded by the Federal Ministry of Education and Research (BMBF) within the ideas competition "New Products for the Bioeconomy" and is supported by Projektträger Jülich (PTJ). The Greenhub is being developed at the University of Leipzig and supported by the founder initiative SMILE.
The innovation lies above all in the high degree of automation of the system. The specially developed, fully controllable LED lamps can be adjusted in a wide wavelength range depending on the plant species. At the moment, experiments on different plant species are being carried out with different light and nutrient recipes. The nutrient supply of the plants is also controlled by a self-developed auto dosing system. Already, over 40 different plant species such as salads, herbs, tomatoes and chilies have been grown at the Greenhub.
