Patent ID: 8725301

Claim:
A computer-controlled ebb and flow watering method utilizing two float switches, two water pumps, a timer, and a control bucket, comprising the steps of: initializing fill time period with a timer; determining the state of a top float switch and a bottom float switch in a control bucket; powering on a fill pump if the top float switch is down; starting an internal timing clock if the top float switch is up; restarting the internal timing clock if the top float switch drops from up to down; shutting off the fill pump if the internal timing clock runs for a complete fill period; initializing drain time period after fill time period ends with a timer; determining the state of a top float switch and a bottom float switch in a control bucket; powering on a drain pump if the bottom float switch is up; starting an internal timing clock if the bottom float switch drops from up to down; restarting the internal timing clock if the bottom float switch raises from down to up; and shutting off the drain pump if the internal timing clock runs for a complete drain period.
