A hydroponic system for nutrient plant culture, designed to overcome the problems of algal contamination, adequate aeration and physical support for the plants is presented. It is based on intermittent floodings of the growth pots, containing lapilli tuff as a supportive medium, with a nutrient solution. The substrate used is capable of holding sufficient water for a relatively long period, yet it maintains good aeration of the roots. The system is simple, inexpensive and requires a low power supply. Detailed technical data are given.
