Drip irrigation is much more efficient than sprinklers
You need an empty jug and a pointy thing
Step 1: Poke a Small Hole in the Bottom of the Jug
Step 2: Fill With Water and Set It Next to a Plant
Pay attention to what time it is (not really necessary)
Step 3: Come Back in a While and See How Much Water Is Left
I got about a gallon per hour and a half.
