The idea of growing plants without watering - fertilizing soil, instead using fish as a natural fertilizing source absolutely fascinated me. Therefore I created my own flood and drain aquaponics version.
The central idea was to use simple materials in order to create an affordable -low-cost hydroponic system. My initial thought was this.
Having an old small (children’s furniture) table i constructed a wooden box in order to serve as the grow bed of my project. I lined it with geotextile, using spray glue a adhered it to cover all pointy edges of the metal corners.
