Abstract
A method of controlling an ebb and flow watering system utilizing existing hardware commonly used in ebb and flow systems including float switches, water pumps, electromechanical timers, reservoir, control bucket, flood lines, indicator LEDs and plant containers such that the filling and draining of the control bucket is improved by accommodating for hydraulic delays, flood line restrictions, and pump limitations, while further providing constant monitoring for leaks or float switch failure, and shutting off the pumps if the same are determined.
