NFT system (also known as nutrient film technology) is a hydroponic planting method with shallow nutrient liquid level (1-2 centimeters), simple design and construction, and low investment cost.
Let’s find out more about this technique.
- There are various ways to design a nutrient film technique system; however, all of them take after the design of a very shallow nutrient solution pouring down through the tubing. The bare roots of the plants will absorb the nutrients in the solutions when they come into contact with the water.
- Although the nutrient solution flowing through the pipeline is very shallow, the roots of the entire plant will always remain moist and can absorb the required nutrients at any time. In addition, its hanging roots have a large contact area with the air and sufficient oxygen, which is also helpful for the growth of plants.
The components of the NFT hydroponic system include:
- Container for nutrient solution
- Nutrient pump
- Circulation pipeline
- Grow tray
Which plants are suitable for NFT irrigation system?
- In the NFT hydroponic system, leafy vegetables such as lettuce, spinach, and microgreens can be planted. These crops grow faster in a hydroponic environment and have relatively low requirements for nutrients and water, making them suitable for planting in an NFT system.
- NFT is not suitable for planting heavy crops that require a lot of support because the roots are not in a culture medium that can withstand a lot of weight.
What are the advantages of NFT irrigation system?
- NFT system reduces water and fertilizer waste through nutrient solution recycling, avoids soil-borne diseases, has good root breathing, is easy to disinfect equipment, and is easy to check growth status. It is environmentally friendly and increases vegetable yields.
Summary:
- The NFT system is a hydroponic cultivation method with simple construction and low investment cost. It is very suitable for fast-growing leafy vegetables, and vegetables can be harvested within a few weeks.
- In addition to vegetables, the system can also be used to grow flowers, such as nasturtiums.、
- The NFT system is widely used in urban agriculture, commercial greenhouses, vertical agriculture, and home gardening. Through these application scenarios, the NFT hydroponic system demonstrates its importance in modern agriculture and sustainable development.
