About vGreens

vGreens is dedicated to the resource-efficient, data-driven production of nutrient-rich foods through vertical farming. Our software solution enables year-round fruit production, irrespective of climate or season. With our inaugural farm, we can cultivate strawberries near urban centers throughout the year, utilizing 99% less farmland, 95% less water, and 95% less fertilizer compared to traditional agriculture. At the core of our technology is a continuously optimizing AI algorithm. It not only creates optimal conditions for plant growth (e.g., temperature or nutrients) but also tailors production parameters to local market demands, such as energy prices, ensuring economical production all year round.
