Finally, I am independent of the green thumbs and good will of my neighbors and friends :-))) My sisters green (plants) thank me because they get the precious liquid regularly. A really ingenious system, easy to install and high top. Each of its plant loves should make their suffering during the summer so that one end. As a useful supplement, I recommend a large Kunstoffwanne or best a box with lid from the hardware store. So you have enough water supply for an extended period.
