The LCD can display all three essential hydroponic nutrients measurements at one time, a 3-second cycle of single measurements, or a real-time graph screen with options for measurement selection and log recall.\u003c\/p\u003e \u003ch3\u003eMonitor changes over time\u003c\/h3\u003e \u003cp\u003eFluctuations in your hydroponic nutrient solution can have lasting effects on your plants. The Groline monitor automatically logs every 15 minutes for 30 days, and stores min, max and average values so you can recognise when patterns arise and help prevent future problems. For review and storage, use the USB-C to easily transfer data to a flash drive or PC using a cable. Files are exported as .csv.\u003c\/p\u003e \u003ch3\u003eGrow with confidence\u003c\/h3\u003e \u003cp\u003eThe Groline monitor frees up your time by doing the testing for you. Simply set high and low alarm levels – if your hydroponic nutrient solution moves out of range a measurement error will display.
