Note* as of July 27, 2016, you should no longer see a 1 minute value. If you do, please update the Edyn app on your phone.
Smart Watering mode takes into account sensor data, and the plants in your garden, when creating a custom watering schedule. If your soil is already at an ideal moisture, it will reduce the duration of future watering events so that you do not waste water. The algorithm updates the schedule every night, so these numbers may change. A 1 minute number means your soil moisture is very close to spot on!
