Hydroponics: NFT and it’s benefits
NFT, nutrient film technique, involves a trough or tube with holes to grow plants such that the roots are dipped in a thin, steady stream of nutrient enriched water. This hydroponics design is perfect for growing plants and also helps to conserve water.
Benefits Of NFT :
1.It conserves water. Since it is never exposed to the hot sun, water loss is limited to the perspiration from the leaves.
2. It conserves energy as it does not require high power pumps or chillers.
3. It produces high yields in scalable greenhouse operations.
4. It does not require any growth medium like soil making it more economical.
5. Numerous plants can be fed water from a small pump since these systems use gravity to trickle water across the roots.
