The principle of the NFT is by which nutrient solutions are recirculated for crop production. The system is widely adjusted for a variety of crop production and ideal for short term crops such as lettuce, leafy crops and herbs. Larger NFT systems are adaptive for long term crop production for example cucumber and tomatoes. This makes hydroponics economically attractive and with such outstanding advantages it is ideal for protection of degradation of natural resources this makes the culture efficient to countries.
