The ideal system for irrigation on vacation and I decided to let it run all summer, because you save a lot of water through optimal irrigation. Compared with the casting of the pot I need less than half of water! That's hard to believe, but the water is right there, where the Plants need it. Contrary to the information of Gardena, the pump creates loose a difference in height of 2 meters. The flowers stand out as being on the parapet of the balcony and the water tap at the bottom. This works flawlessly! The same applies to the number of dripper in a row. I have loosely times 10 - 20 depend on a drip hose. Since the pump has 3 connectors for hoses, one can thus irrigate a lot dropper or pots so. Now missing still functioning adjustable dripper. Unfortunately, the in Gardena offer dissemble always after a short time. A test with the prescribed amount of adjustable dripper on a hose did not work in the long run. They disguise themselves after a few days and it drips virtually nothing left out, however, to be or otherwise without clogging! Otherwise I can only recommend the system!
