Abstract
An ebb and flow watering system having controls for starting an internal timing clock when a fluid in a control bucket reaches a fill level, restarting the internal timing clock if the fluid drops below the fill level, and shutting off the fill pump if the internal timing clock runs for a complete fill period; and starting an internal timing clock when the fluid in the control bucket reaches a drain level, restarting the internal timing clock if the fluid raises above the drain level, and shutting off the drain pump if the internal timing clock runs for a complete drain period.
