This hydroponics set up can be easily made using household items.Only thing you will have to buy is the nutrient solution.
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 case 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 recirculate the water back into the first reservoir manually. This method keeps the medium regularly flushed with nutrients and the solution mix can be reused.

Step 4: Solution Reservoir

In this case a normal bucket was used and a Spigot (Tap Valve) was attached at the base of the bucket to allow the chemical mix to drip at a low rate.

Step 5: Planter Containing the Hydroponic Medium and Plants

A plastic Planter was filled with tiny rocks and pebbles which acted as the hydroponic media through which the solution would flow.
A tiny hole was perforated at the base of the planter to allow the solution to fall into another bucket to be reused.

Step 6: Drainage Bucket

Once the drainage (collector) bucket is filled, one must recirculate the water back into the first reservoir manually. This method keeps the medium regularly flushed with nutrients and the solution mix can be reused.
