Nutrient Film Technique: Similar to Deep Water Culture and popular commercially. Consists of a water reservoir, a pump and a separate growing tray for the plants. The water is pumped from the tank to the tray which is sloped to cause the water to flow from one end to the other to water the plants. When the water reaches the other end, it flows back into the reservoir.
