Blumat Drip Automatic Watering Sensors – 2 Pack

The heart of a fully automatic drip system. The Blumat Drip Sensor uses a sealed ceramic sensor that opens as the soil dries and closes when it's moist — so every plant sets its own watering schedule with no apps or timers. Connect to a reservoir or a hose with a pressure reducer; the brown knob fine-tunes each sensor to the plant and medium. Great for beds, planters, and containers. 2 sensors, each with a tee.
