By reusing household items you are reducing waste. Because this setup is outside you are using sunlight and no artificial light is required.The water and nutrient solution mix can be reused.
A reservoir consisting of a bucket with Spigot (Tap Valve) attached at the base contains the nutrient solution and is placed above a tray filled with the hydroponic medium which in this cases happens to be small pebbles. The nutrient mix is allowed to drip at a low rate providing a constant supply of the solution to the roots. The solution after having gone through the container housing the hydroponic medium and plants is then drained and collected in another bucket. Once the drainage (collector) bucket is filled, one must recirculation the water back into the first reservoir manually. This method keeps the medium regularly flushed with nutrients and the solution mix can be reused.
