Gardena Water Timer FlexcontrolThe GARDENA FlexControl makes garden irrigation easier for you. This means that you don't have to worry about watering either in everyday life or while you're away from home. On top of this a Rain Sensor or Soil Moisture Sensor can be connected to the Water Computer. This way, when it rains, or if the soil is already moist enough, the programmed irrigation is cancelled, thus saving valuable water resources.
