WaterScout SM 100 Sensor - 6ft(1.8m)
[SP06460]

Maintaining a healthy water balance is essential for producing high quality plants. Under-watered plants suffer from nutrient deficiencies, stunting and wilting. Conversely, over-watered plants are more susceptible to disease pressure and less tolerant of dry conditions later on in their life cycle. Extreme over-watering will suffocate the plant and lead to root death. The new Spectrum WaterScout SM 100 Soil Moisture Sensor measures soil moisture with little or no disturbance to the root zone. The thin shape and pointed tip allows for easy insertion into the soil or growing medium. Use the Soil Moisture Reader to take fast and accurate spot readings. Or, bury the sensor and track soil moisture changes over time with a WatchDog® data logging weather station (with Spec 9 Pro Software). Not compatible with 400/200 loggers. WatchDog Stations sold prior to 2009 must be upgraded.
