Spin-Fert at the University of Hohenheim’s Open Day 2025

Stuttgart, Germany

University of Hohenheim

On July 5, 2025, the University of Hohenheim welcomed the public to its annual Open Day. As part of the event, the Spin-Fert project was presented at a joint booth with the Moor-Power project, drawing attention to the importance of peatland protection and the development of peat alternatives in horticultural substrates.

Under the shared title “Smell, guess, protect: moor protection quiz meets memory nexus”, Spin-Fert engaged visitors with a unique smell-based memory game, designed to explore the sensory perception of different growing media. Participants were invited to smell and reflect on two contrasting substrate samples. The activity attracted broad interest: more than 130 people took part, ranging from curious children to experienced gardeners and academics.

Following the memory game, visitors had the opportunity to explore a variety of peat alternatives displayed at the booth. These included different materials currently being tested or used as components in peat-free or peat-reduced substrates. The hands-on display allowed for direct comparison of texture, structure, and appearance, sparking many in-depth conversations about practical use, environmental impact, and future potential. 

Alongside Spin-Fert’s contribution, the Moor-Power project offered a peatland quiz that challenged visitors’ knowledge on topics like climate protection, rewetted moors, and the use of solar energy in these sensitive ecosystems.
