Size a drip system and set a timer that delivers the water your plants actually need. Enter the number of emitters on the zone and the rated flow of each in gallons per hour, and the calculator totals the system flow in gallons per hour and per minute. Enter how many gallons you want to deliver in a session and it tells you the run time to set on your controller, plus the water used per day if you run it daily. Drip emitters commonly come in half, one and two gallon per hour ratings, and matching total flow to your plants avoids both drought stress and waterlogging. Because drip applies water slowly at the root zone, it wastes far less than a sprinkler. Everything is calculated instantly in your browser with no signup.
