NFT, written out as Nutrient Film Technique, is the favored method of commercial hydroponic cultivation. A small film of nutrient solution runs beneath individual planting sites, providing your plants a steady stream to feed from while growing. Smaller non-fruiting plants work best …in these systems, such as lettuce, spinach, and other leafy greens. Spaced planting sites allow for room for roots to develop, and recirculating reservoirs and lines drastically reduce the water needed to operate system.
