looks good, easy, for widths up to 75 cm thoroughly recommended, but my 100 cm wide in the center with slight dishing outward when the are completely filled and fully bewössert. Remedy something when you consolidate after the first planting, soil, watering, then the box in the middle which compresses, so that the earth is pressed slightly to the side and the pressure on the sides in the center is relieved somewhat. So wet as directly after planting in Erstbewässerung you never makes it back later yes.
