Sinterra

Sinterra is a German agtech startup that has developed the Hydrostarter, a reusable and recyclable propagation and cultivation device designed for controlled environment agriculture. By enabling plant growth without the need for traditional, single-use substrates such as mineral wool or peat, the technology seeks to reduce waste and environmental impact. The system uses capillary action to supply water to seeds, allowing roots to grow directly into the water, which supports various crops ranging from leafy greens to vine crops. The device is designed to be cleaned and reused, offering a circular solution for both commercial vertical farms and private hydroponic growers.

This innovation addresses the environmental challenges and supply chain dependencies associated with disposable hydroponic substrates. By eliminating the recurring acquisition costs and waste of single-use media, the Hydrostarter aims to improve the sustainability and efficiency of indoor farming operations. The company is currently focused on refining its product for series production and actively seeks partnerships with firms, research institutions, and investors to scale its technology for broader global availability.
