Gardena SPRINKLERSYSTEM sprinklers can be permanently installed below ground and linked together as one complete network - with all the pipelines and system components buried and out of sight. The sprinklers pop up to water your lawn when they're needed and and then sink back out of sight when the watering session has finished - so you'll hardly know they're there, The MD range of pop up sprinklers are designed for medium sized areas and have a rotary spray pattern for low precipitation rate. The MD80 is suitable for watering areas of up to 80 square metres and is designed for irrigation of taller plants.
