While standard sensors only track moisture, the WCS 2 provides a comprehensive "look inside" your medium by measuring Volumetric Water Content (VWC%), Pore Water Electrical Conductivity (EC), and Root Zone Temperature simultaneously. By monitoring these three critical variables, you can master the art
