As a longtime fan of Rain Bird's irrigation systems, our garden editor was thrilled to discover the company has built even more smarts into its new WiFi-connected timer. The watering schedule will automatically adjust based on the local weather to keep your water usage down, but can also be modified via a mobile app. What's more, it offers up to eight customizable watering zones, allowing you to really target your water usage where it’s needed and cut down where it isn't.
