Seeds or seedlings are placed in pot-like cups that are filled with soil substitutes such as rock-wool or coco fiber. Water and nutrients are added to system where they are circulated through plants. A simple interface lets the user control and monitor pH, moisture, light and more. Looks like a pretty futuristic design. Not quite sure about how the water will circulate.
