Grow fresh, organic herbs and (micro)greens in your kitchen all year long without much effort and help reduce energy costs at the same time. (less food transportation) Fresh cut greens are much higher in nutritional value.
All the watering, the lightening schedule is automated. The Urban Cultivator is hooked up to city watering. Uses a third of energy a bar fridge uses and comes in a commercial and residential version.
According to the manufacturer it pays itself back within 1-3 years (depending on the greens and herbs you grow).
