Korea: Growing vegetables in city buildings

In Korean cities nowadays, there's a growing number of so-called urban farms, where people use efficient methods of growing vegetables. The plants grow in a vertical framework and are sprayed with mist.

"The growth rate of these vegetables is very fast because the roots are exposed to the air," the manager says. This store, situated in the center of a city, is also a vegetable farm.

It's unique in that there is a tank full of fish at the end of each frame where vegetables grow. Water circulates between the vegetables and the tank.
