Regular Price $295.00

TrolMaster’s Soil Moisture Temp and EC 3-­in­-1 Sensor with Cable Set

Monitoring your grow medium for proper water content % and EC is an important factor in high-yield growing applications. TrolMaster understands that today’s method of “crop steering” involves more precise control of the amount of nutrient and the nutrient strength within the grow medium in order to achieve the best results. The WCS-2 Water Content Sensor provides the users with an accurate and simple way to monitor your grow medium. The WCS-2 consists of a multi-prong sensor assembly that is inserted into your grow medium. Once the WCS-2 is calibrated to your grow medium and your nutrients, you will get constant readings from the WCS-2 providing the actual water content within the grow medium, the temperature of the grow medium and also the EC within the grow medium. You can even select alarm “limits” for each variable being monitored by the WCS-2 to send remote notifications through the TrolMaster or TM+ apps.
