LED (Light Emitting Diode) is a semiconductor of p-n junction diode which is capable of producing light spectrum which can fulfill the need of light of plants for the process of photosynthesis. Advancement in this field will lead to advancement and increase efficiency of hydroponics. Hydroponics is a new technology under which farming can be done at places where land is not fertile. After the emergence of LED grow lights it is possible to grow plants and perform farming and practice of agriculture in places where is less availability of sunlight. In future it is expected that these lights and hydroponics will lead to end the hunger condition in the world. It will definitely increase in agricultural production. After the emergence of combination it is possible to grow plants and perform agricultural activities in bad weather condition areas.
Various scientific experiment is done on combination of grow lights and hydroponics. It is said to expensive in first phase but will prove to be economical and environmentally safe after short period of time.
