The GARDENA water-saving Drip Irrigation Line for above-ground and underground installation with integrated Drip Heads lets you irrigate rows of plants up to 25 m long, such as hedges, bushes and shrubs. The easy to lay Dripline is the ideal add-on for the Micro-Drip-Irrigation Sets Hedges/Bushes (Art.-No. 13500-20 and 13501-20). You can decide whether you would prefer to install the pipe above or out of sight below ground. Thanks to the special self-clean function with labyrinth technology and root barrier, the pipe cannot get blocked. A Drip Head is integrated in the Drip Irrigation Line every 30 cm, which constantly releases 1.6 litres of water per hour. This ensures that your plants are irrigated evenly. The Drip Heads are pressure-compensating and easily cope with differences in height, such as on a slope. If you want to branch your line quickly and easily, use the separately available 13 mm connectors with patented Quick & Easy connection technology. All 13 mm components of the Micro-Drip-System are reusable and therefore sustainable. They won't get damaged even after repeated use. Micro-Drip-System. Caring for your plants and every precious drop. Easy, accurate, water and time-saving irrigation.
