Question about Gardena Balcony Watering

I also have this set and use it to water pots from a rain barrel. With this set, you build a single pipe that goes through all the pots/geranium boxes, so it's particularly suitable if you have everything in a row. You can also set how long and how often it should water. The water is slowly released drop by drop.
With Gardena holiday watering set (drip irrigation set), for example, all pots are watered directly from 3 distributors, so it is better if you have all the pots next to each other. In addition, you cannot choose how often it waters.
