Hydroponics, by definition, is a method of growing plants in a water based, nutrient rich solution. Hydroponics does not use soil, instead the root system is supported using a medium such as perlite, rock-wool, clay pellets, peat moss, or vermiculite.
The basic premise behind hydroponics is to allow the plants roots to come in direct contact with the nutrient solution, while also having access to oxygen, which is essential for proper growth.
The nutrients that the plants normally derive from the soil are simply dissolved into water instead, and depending on the type of hydroponic system used, the plant's roots are suspended in, flooded with or misted with the nutrient solution so that the plant can derive the elements it needs for growth.
There are many advantages in growing without soil. Some hydroponic farmers have found they get yields many times greater when they switch from conventional methods. Because hydroponically grown plant roots sit directly in nutrient-rich solutions, they get what they need far more efficiently than plants growing in soil, so they need much smaller root systems and can divert more energy into leaf and stem growth.
Hydroponic farming is a widely used practice and there are many ways to grow produce using these systems. Depending on your needs, Hydroponic farming can be used from small home gardens, offices and even schools who are looking to engage in sustainable farming practices. Overall there are 6 main systems and these are; Drip System, Ebb & Flow, N.F.T, Water Culture, Aeroponics, and Wick.
