Vertical farming/urban farming is a plan to grow produce in vertical, multi-story structures within urban areas to reduce the dependence on food grown and transported long distances.
Vertical farming will be using new versions of hydroponics and aquaponics. It will use about 100 times less water and provide over 5 times greater energy efficiency. The system can provide positive monetary returns within two years.
