Hydroponic farming offers several environmental benefits when compared to traditional agriculture. The most significant of these is reduced water consumption and controlled nutrient usage. Hydroponic systems can use up to 90% less water when compared to conventional farming.
Simply put, hydroponics is the practice of growing plants using only water, nutrients, and a growing medium. The word hydroponics comes from the roots hydro, meaning water, and ponos, meaning labor, this method of gardening does not use soil. There are several types of hydroponic systems. Plant roots grow down through a medium while an absorbent wick draws nutrient-filled water up from a water reservoir to the root system zone. The growing medium allows for air (oxygen) to reach the roots. Hydroponics is a type of horticulture and a subset of hydroculture which involves growing plants, usually crops or medicinal plants, without soil, by using water-based mineral nutrient solutions in an artificial environment. Hydroponics is a method of growing plants without soil, using nutrient-rich water to deliver everything plants need directly to their roots. The word hydroponics comes from the Greek for working with water and is a method of growing plants without soil.

Hydroponics is the art of horticulture without soil. Hydroponic is a Latin word meaning working water. In the absence of earth, the water provides nutrients, water, and oxygen to the plants life. The hydroponic system is all about soilless farming.
