The Green Wheel’s large growing area helps to cultivate a greater number of plants, as does the project’s illumination design. All plants are arranged around the light source that lies at the center of the wheel, helping to reduce lighting consumption. Meanwhile, the wheel’s gravity effect supposedly helps optimize herb and vegetable production. The outer case hides an engine that rotates the plants, and the rotary garden also includes a water reservoir and pump for automatic plant irrigation. Inside the perforated inner wheel are vases made from coco fiber that provide support for plants and their roots.
