How long to run drip irrigation?
Choose how many gallons you want to deliver. Your zone’s flow sets the minutes on the timer.
Estimated run time
Enter a water target and zone flow greater than zero.

How the timer estimate works
Divide the target gallons by the combined gallons per minute of the emitters running together. If the flow is listed in gallons per hour, divide it by 60 first. For example, a 30 GPH zone delivers 10 gallons in 20 minutes.
Choose the water target using your crop, soil moisture and recent rainfall. An open-outlet bucket test measures the water source. Use the flow through the running drip zone for this estimate.
Plan a new raised bed layout or size the flow for your rows.
