A vertical farm is a closed and controlled environment where plants grow vertically in a tower structure. That structure saves space horizontally.
In a vertical farm, traditional soil is not used in planting. Instead, aeroponics (where plants are cultivated in the air with the help of an aqueous nutrient liquid) and hydroponics (water-filled containers) are used. The light is generated with the help of special LED lights that simulate the light spectrum of the sun. Furthermore, the growth of crops within the tower is optimized as we can control the climate.
