In non-aggregate or liquid hydroponics systems, no rigid supporting media are necessary. Such systems are closed, since plant roots are exposed to the nutrient solution without the mediation of a growing medium. The solution can be re-circulated and reused. The most common method of engineering a liquid hydroponics system is the nutrient film technique. The nutrient solution flows through supported polyethylene film liners or PVC piping that contains the plants roots.
