Maintaining a healthy soil moisture and 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.

Measures Volumetric Water Content (VWC) of soil
Capacitance-type sensor responds immediately to changes in soil moisture content for better irrigation decisions
Calibrated for mineral soils or soilless media
Installs easily into 3/4 in (1.9 cm) hole
Install permanently or use to take spot measurements
