Description by kobosil.me Development(from the App Store)
DrainMaster Plus shows you whether your plants get the right water and feed. Measure what goes into the pot and what drains out, and the app warns you early when salt builds up or the pH drifts. Every plant gets its own journal.
Track electrical conductivity (EC), pH and temperature of your feed (nutrient solution) and of the water that drains out (runoff), in µS/cm, mS/cm or PPM (TDS). Calculators for humidity (VPD chart), light (DLI) and EC to PPM, a nutrient calculator for mixing and a grow journal (grow log, plant diary) with photos. For soil, coco coir, hydroponics, houseplants and indoor growing. Live readings over Bluetooth from compatible meters (pH meter, EC meter, pH pen).
