The GARDENA Above Ground Drip Irrigation Line serves the irrigation of smaller plant areas in flower- or vegetable gardens, and of plant rows. The drip head spacing in the pipe is 30 cm, each head gently waters 1.5 l/h. Thanks to the innovative labyrinth technology, the drip heads are self-cleaning. Through the small diameter of 4.6 mm (3/16"), the Drip Irrigation Line is especially flexible and easy to install. When the Master Unit is fitted with a T-Joint (art. 8330) in the middle, the Drip Irrigation Line can be extended with the Extension Pipe art. 1362-20; the maximum length is 30 metres. The Drip Irrigation Line is supplied ready-to-connect with the Master Unit 1000 and Plugs and has a length of 15 metres.
