Farmers are now growing food without soil and sunlight

Urban farming is evolving at a fast pace in Europe. While the idea of growing food in cities was popular after the World War II itself, the recent developments in science have managed to help farmers to take it to the next level.

They are currently making use of abandoned warehouses to underground bomb shelters to grow crops and that too, without sunlight and soil.

The process is done with the help of Hydroponic Systems. They make use of porous materials where the roots of the plants grow. Instead of sunlight, this system makes use of low-energy LED. According to studies, crops made in such a way have a higher yield and need only less water.

Though the technique is currently sophisticated and expensive, there are some affordable and easy to use versions that are poking up all around the world.
