    Automatic and time-saving irrigation

    Using a GARDENA Water Control, your garden can be reliably and conveniently watered – even if you are not at home. Resulting in more leisure time, a lush green lawn and beautiful, healthy plants. If the automatic irrigation system is started in the early morning hours or the evenings, less water evaporates. This saves money and ensures targeted, optimised irrigation.

The weatherproof operating unit can be removed during programming. The key lock feature ensures that programming is childproof.

    Flexible irrigation with 6 schedules

    Six independent schedules can be created for irrigation purposes. The start, duration and weekdays of the irrigation can be adjusted. Highly flexible plans can be set according to your personal tastes. Plant connoisseurs use this for example for additional pre-watering which prepares the soil and roots for the later, main irrigation. This improves the water absorption and plant growth.

    If the weather changes, the watering duration can be reduced centrally in 10% steps or the irrigation can be stopped during a phase of bad weather for 1 to 7 days.

    ‘Safe Stop’ technology

    The Water Control always works reliably thanks to the ‘Safe Stop’ technology. If battery levels are too low to complete an irrigation cycle, then the cycle is not commenced. The battery level indication on the display also tells you when the battery has to be replaced.

    Water-saving operation

    When used in conjunction with the GARDENA Soil Moisture Sensor, automatic irrigation is not activated if soil moisture levels are sufficient. This delivers optimal irrigation to plants and reduces water wastage.
