NFT (Nutrient Film Technique)
NFT (Nutrient Film Technique) is a popular growing method used in modern indoor farming and vertical agriculture. It's a way of growing plants without soil where a very shallow stream of water containing dissolved nutrients flows past the plant roots. Think of it like a constantly moving film of nutrient-rich water that feeds plants. Farmers and growers use NFT systems because they save space, use less water than traditional farming, and can be set up in layers for vertical farming. This method is especially popular in growing leafy greens, herbs, and some vegetables in indoor farms and greenhouses.
