On Demand Arduino Watering System

A cool 8 zone Arduino Watering system I use to water my fruit trees with JUST the water they require at JUST the time they need it. Avoiding wasted watering of weeds etc. Included is sketch I use on NANO which does entire control.

Can you provide us with more detailed information on the scheme and the necessary materials. Thanks in advance!
