ABSTRACT:
A hydroponic nutrient solution control system capable of performing the nutrient solution control automatically, accurately, effectively, and efficiently. In the system, the supplies of the acid nutrient ion ingredient solutions and the alkali nutrient ion ingredient solutions from the acid solution tanks and the alkali solution tanks to the nutrient solution tank are controlled according to the pH measured by the pH meter and the ion concentrations measured by the ion analyzer. The system may also controls the supplies of the high concentration nutrient solutions and the water from the high concentration nutrient solution tanks and the water supply according to the electrolytic conductivity measured by the electrolytic conductivity meter.
