Nutrient Film Technique (NFT)

Nutrient Film Technique (NFT) is a hydroponic growing system where a thin film of nutrient-rich water flows continuously over the plant roots, providing them with water, nutrients, and oxygen. The plants are typically grown in a sloped channel that allows the nutrient solution to flow back into a reservoir for recirculation. NFT is commonly used in commercial hydroponics to grow leafy greens and herbs with minimal water use and efficient nutrient delivery.
