Gardena’s Micro-Drip-Irrigation Hedge/Bush Set (50 m) is a ready-to-use kit for uniform watering of long plant rows. Article 13501-20 includes one Master Unit 1000 pressure regulator, 50 m of 13 mm drip irrigation line and a 13 mm end plug. Integrated, pressure-compensating drip heads are spaced every 30 cm and deliver 1.6 l/h each, keeping flow constant even on slopes. The line can be installed above ground or buried; a labyrinth design with root barrier helps prevent clogging. The set covers up to 50 m of hedges or borders and can be extended to 100 m per line, or up to 140 m with the Master Unit positioned in the middle. Connects directly to a household tap; no pump or reservoir is included.
