Automatic and time-saving irrigation

With a GARDENA Water Computer, your garden will be reliably and conveniently irrigated – even when you are not home. You win more free time and have a lush, green garden and beautiful, healthy plants. With the automatic irrigation in the early morning hours or evening, less water evaporates. This saves money and allows targeted, optimal irrigation.

Flexible irrigation control

It could not be more flexible. For irrigating your garden, you can choose up to six watering programmes daily. The watering duration can be set from one minute up to 9 hours 59 minutes. For additional flexibility, you can freely select the desired watering days. If irrigation is to be started immediately, it can also be manually activated.

Water-saving operation

With the connection of a GARDENA Rain- or Soil Moisture Sensor, the automatic irrigation is interrupted depending on the soil moisture and natural rain. With the GARDENA Soil Moisture Sensor, the irrigation can also be controlled solely based on the sensor.
