How it Works:
- You put the supplied gypsum block in the root zone of your crop and then hook up to the display unit.
- Seven yellow dots tell you that your soil is wet.
- As the yellow dots flip back to black you know that your soil is drying out.
- No Electricity Needed! Runs off 2 AA Batteries!
- Sensor is readable from 30 feet away and you can extend the sensor wires up to 300 feet!
GDot can be moved from one sensor to another or left at one sensor. We recommend putting one sensor deep and one shallow.
Includes One 5-foot’ Sensor (Additional ones available, see Related Products – Irrometer Soil Sensors)
