Real Data Ultimate Control

Spruce provides all the tools to water most efficiently. All, automatically.

Get up and running fast with simple setup. Tell Spruce basic information for each zone and we'll customize the watering. With a touch of a button, adjust watering with time of year and adapt to rainstorms with hyper-local weather predictions.

Optionally, pair Spruce Sensors to a zone for real time soil moisture feedback. That way, Spruce will water only when you need it, for as long as you need it.

Measure what Matters

Spruce Soil Moisture Sensor Depth

Measure where it matters. Spruce sensors are designed to measure soil moisture 3-5 inches below the surface. This reaches the typical grass root zone depth of 4-6 inches below the surface.

Measuring at least several inches below the surface is critical. This promotes deeper root growth and heartier, healthier plants.

Accurate Measurement

Pair Spruce with any compatible 2-wire flow meter for real time water use.

Wired flow meters offer higher accuracy and always on, real time measurements that wireless solutions can't match.

Calibrate each zone and receive notifications if flow deviates or a leak is detected. Set Spruce to turn off water if flow is over or under set limits. More details at Flow Meter FAQ
