Gardena Flex Irrigation Controller, Black/Grey, Plastic

The Gardena Flex Irrigation Controller 01890-20 is a tap-mounted controller that automates sprinkler operation. It works as a programmable timer, regulating water flow for plants on terraces and balconies. It accepts a maximum input pressure of 12 bar, suitable for standard high-pressure household supplies. The unit connects directly to a tap via 26.5 mm (G 3/4) or 33.3 mm (G 1) threads. Short watering cycles make it suitable for container plants and drip irrigation setups. Automated schedules keep moisture levels consistent without manual intervention.

The controller is made of plastic and designed for outdoor use, mounted directly on the tap. The grey and black housing protects the internal timing mechanism and user interface from weather exposure. Installation is straightforward — the unit screws onto the tap thread without tools. Removing the controller for winter storage or maintenance is just as simple: it unscrews in the same way. An integrated LCD shows the current settings and programmed watering schedule. If the battery is too low to close the valve, the unit blocks watering. Manual watering can be started with the button on the front panel.
