DrainSense

DrainSense is Sigrow's wireless drain sensor for soil-based and substrate-based greenhouses. It continuously measures drain EC, pH, temperature, drain volume and live gutter weight at a 5-minute interval, with 0.5% load cell precision. Because it measures the water leaving the root zone and the gutter weight, not the substrate itself, it works on every greenhouse substrate: rockwool, coco, coco peat, perlite and soil. Growers use it to steer irrigation on real drain data, resolving drain EC shifts under 0.3 mS/cm in real time. Solar-powered and fully wireless; integrates with HortOS, Argus and Priva.
