DWC is advantageous for growing fast-growing, water-loving plants such as lettuce, basil, and cannabis, providing a highly efficient hydroponic solution.
Nutrient Film Technique (NFT)
Nutrient Film Technique (NFT) operates by continuously circulating a thin film of nutrient solution over the roots of plants, which are supported by a slightly sloped channel.
This method offers several advantages, including efficient nutrient delivery and minimal water usage, making it particularly suitable for fast-growing, lightweight crops such as lettuce and herbs.
Understanding the operational mechanics, benefits, and ideal plant types for NFT can greatly enhance hydroponic productivity and sustainability.
How NFT Works
The Nutrient Film Technique (NFT) operates by continuously circulating a shallow stream of nutrient-rich solution over the roots of plants, ensuring peak oxygenation and nutrient uptake.
This method involves the use of sloped channels, usually made of PVC, where a thin film of nutrient solution flows.
The solution is pumped from a reservoir to the higher end of the channel, allowing gravity to facilitate its flow back to the reservoir.
This continuous circulation prevents stagnation and promotes nutrient absorption. The film’s thinness is critical, as it exposes the root zone to ample oxygen, reducing the risk of root diseases.
Precision in maintaining the correct slope and flow rate is essential for the most favorable plant growth, making NFT a highly efficient hydroponic technique.
