The Nutrient Film Technique (NFT) is a hydroponic growing method where a thin film of nutrient-rich water flows over the roots of plants. This technique allows the roots to absorb essential nutrients while also receiving oxygen, promoting healthy growth. In NFT systems, plants are typically placed in channels or troughs, where the water continuously circulates. This efficient use of water and nutrients makes NFT a popular choice for growing various crops, including lettuce and herbs, in controlled environments like greenhouses or indoor farms.
