What is Nutrient Film Technique (NFT)?
Nutrient Film Technique, also known as NFT, is a hydroponic system that utilizes a shallow nutrient solution to nourish plant roots. In an NFT system, plants are placed in gutters or tubes with a slight slope, allowing a thin film of nutrient solution to flow past the roots. This constant flow of nutrients ensures that plants receive a continuous supply of water and essential nutrients. Unlike Deep Water Culture (DWC) systems, NFT systems use a low volume of water, which can result in temperature fluctuations and challenges in distributing nutrients evenly.
To set up an NFT system, you will need gutters or tubes with a gentle slope, a pump to circulate the nutrient solution, and a reservoir to store the solution. The roots of the plants are suspended in the gutters, allowing them to absorb the nutrient-rich film. One of the advantages of NFT systems is the ease of examining the roots of the plants, as they are exposed and visible. This visibility makes it easier to identify and address any root-related issues.
However, NFT systems require closer monitoring compared to DWC systems. The low volume of water in NFT systems means that any imbalance or interruption in the flow of nutrients can have a significant impact on plant health. Additionally, the shallow nutrient film can be prone to drying out if the system experiences a power outage or pump failure. Proper monitoring and adjustments are necessary to maintain optimal nutrient flow and prevent any adverse effects on plant growth.
In summary, Nutrient Film Technique (NFT) is a hydroponic system that uses a shallow nutrient film to nourish plant roots. While NFT systems offer benefits such as water savings and easy examination of roots, they require closer monitoring and may not be ideal for beginners. Consider factors such as your level of experience and ability to closely manage nutrient flow when deciding whether NFT is the right hydroponic system for you.
