NUTRIENT SOLUTION SUPPLY METHOD

摘要

PURPOSE: A nutrient solution supplying method is provided to prevent the environmental contamination by the excessive usage of a nutrient solution, and to reduce the cost for supplying the nutrient solution. CONSTITUTION: A nutrient solution supplying method comprises the following steps: operating a nutrient solution pump(10) for supplying a nutrient solution to a crop storing tray(30) from a nutrient solution container(20); detecting the flow of the nutrient solution from the lower side of the crop storing tray using a sensor member(40), and transmitting the detected signal to a controller; and stopping the operation of the nutrient solution pump using the controller for stopping the supply of the nutrient solution.
