Vegetables' intelligent journey

People can live intelligently and now, so can vegetables.

Cultivated with water, these pesticide-free vegetables are grown without soil in a vegetable planting factory located in southeast Beijing's suburb area.

The 10,000-square-meter factory is under a transparent cover that resists strong ultraviolet light and can be washed by rainfall. Inside the temperature controlled factory, eight types of vegetables including lettuce and spinach become mature on planting beds.
