Hydroponics is a technique that allows growing plants without the use of soil. Plants are kept in small pots that are immersed in nutrient-rich water. Their roots are then able to absorb the nutrients plants require directly from the nutrient-rich water. It is increasingly common to see families set up such systems in backyards or passageways to grow a good amount of fresh green vegetables and fruits that are used on a daily basis. Come to see farms that use such techniques with stunning effect, and also learn how to set up a simple system in your own house.
