This dropper is one of the major building blocks in a perfect automatic irrigation system. The Troper can be really adjusted continuously without any problems. Other Gardena drippers emit constant eg 2 or 4 liters per hour - so that one is in my opinion for greater plant populations much too inflexible. Thanks to the adjustable Troper and other irrigation devices of Gardena, I can now irrigate actually easily both the beds (about 100m) and approximately 30 potted comfortable individually. Although it takes a few days at the beginning until you have all the plants set to the required water demand, but the fine adjustment daily cost only a few seconds. The extra time I enjoy as described in the Vorrezension.
Small criticism of Gardena: Unfortunately, I have some paid to learn the hard way until I have the perfect components found because the product (Buyer's guide) unfortunately leave much to be desired and the operating instructions in a bit confusing offer, especially before buying, partly. And it will be surely ausstezen hardly anyone the professional advice of the DIY adviser, or ?! ;-) A small guide "for what purpose the right components" could help here. Or is it about Gardena quite right that you first paid money for unnecessary Try? (Something like that is common Preaxis unfortunately in too many companies).
