NFT vertical A frame system
Nutrient film technqiue, or NFT, places plants inside channel gutters so that it's roots come into direct contact with shallow streams of nutrient infused water. The gutters are angled in a downward slope so that the water automatically travels down in a constant flow cycle, recirculated back up by water pumps. This allows the roots to have direct water and nutrient source 24/7, without the need for daily watering of plants. NFT is most commonly used for leafy vegetables such as lettuce, and various leafy vegetables.
