Deep Flow Technique
The deep flow technique (DFT) relies on a deep flow of nutrient solution that flows through PVC pipes to which plastic net pots with plants are fitted (See Figure 14.18). The plastic pots contain planting materials and their bottoms touch the nutrient solution that flows in the pipes. DFT systems rely on the introduction of oxygen along the entire length of each growing channel so that oxygenation rates in the root zone are continually kept high enough for good root growth. The PVC pipes may be arranged in one plane or in zig zag shape depending on the types of crops grown.
