A modular hydroponics system for growing plants includes a frame or framework of one or more cages, wherein each cage preferably includes, a source of electrical power and water, at least one moveable light source and at least one moveable circulating fan. Plants are arranged on benches in ebb & flow containers in a stadium arrangement. A mechanism moves the light source along the benches and a reflective hood directs light to the plants. The fan circulates air to control the air temperature within the framework. A watering system supplies and collects water to and from the plants. The pH and nutrient levels in the water is monitored and controlled.
