Peter Sänger's love for plants was, so to speak, born in his parents' horticultural business. After school, he studied at the University of Applied Sciences (HTW) Dresden with a focus on production management and business management and a specialization in horticulture. During his work in a research team at the HTW, he gained extensive knowledge regarding innovative cultivation methods, vertical planting systems, biofiltration, and moss cultures. His studies focused not only on plant sciences but also on economics, finance, and business management. During his studies, he founded Green City Solutions together with three partners. As CEO of Green City Solutions, he is responsible for the strategic orientation and further development of the company. To compensate for this demanding job, he still often finds himself between the mosses.
