NFT (Nutrient Film Technique) hydroponic system is a popular and efficient method of growing plants without soil, using a continuous flow of nutrient-rich water. It is widely used in hydroponics due to its simplicity, low water usage, and ability to produce high yields. Here’s how it works and its key features:

How an NFT System Works:

1. Channel or Gully:
   • Plants are placed in a slightly sloped, shallow channel or gully (often made of PVC or similar material).
   • The roots of the plants are suspended in the channel, allowing them to access water, nutrients, and oxygen.
2. Nutrient Solution:
   • A thin film of nutrient-rich water is continuously pumped from a reservoir into the top of the channel.
   • The water flows down the slope by gravity, passing over the roots of the plants.
3. Root Exposure:
   • The roots are not fully submerged in water. Instead, they are exposed to the thin film of nutrient solution and the air, which provides oxygen for respiration.
4. Recirculation:
   • After flowing through the channel, the nutrient solution drains back into the reservoir, where it is recirculated. This makes the system water-efficient.

Key Features of an NFT System:

• Continuous Flow: The nutrient solution flows constantly, ensuring plants have access to water and nutrients at all times.
• Oxygenation: The thin film of water allows roots to access oxygen from the air, preventing root rot and promoting healthy growth.
• Minimal Growing Medium: NFT systems typically use little to no growing medium (e.g., clay pebbles or rockwool cubes are sometimes used to support seedlings).
• Scalability: NFT systems can be expanded easily by adding more channels, making them suitable for both small-scale and large-scale operations.

Advantages of NFT Systems:

1. Water Efficiency: The recirculating system uses less water compared to traditional soil-based gardening.
2. Faster Growth: Plants often grow faster due to direct access to nutrients and oxygen.
3. Space-Saving: NFT systems are compact and can be set up vertically or horizontally.
4. Low Maintenance: Once set up, NFT systems require minimal maintenance.
5. Clean and Soil-Free: No soil means fewer pests and diseases.
