Abstract: An irrigation system for plants comprises at least one elongate plant through a main pipe with a first, greater cross-sectional area, a plurality of openings distributed in the longitudinal direction and positioned in the bottom of the plant trough, and a plurality of branch pipes each with a second, smaller cross-sectional area. The branch pipes connect the main pipe to the openings. The main pipe is further connected to means for supply and discharge of water. The water level in the plant trough is regulated by supplying or discharging water to and from the main pipe. In manufacture, the means are arranged on a frame belonging to a cultivation table.

Abstract: An arrangement in a box is disclosed, the box being, in the initial position, in the form of a sheet-like blank having a bottom (2), first and second sidewalls (4, 6) which are connected to the bottom (2) via fold lines (8, 10) and are substantially parallel panels which are connected to one of the sidewalls (4, 6). The arrangement is characterized in that a flap (32) is formed at a second panel (20) which, via a second fold line (18), is connected to a first, inner panel (16) which is connected to one of the sidewalls (4, 6) via an inner fold line (14), and that a slot (34) is formed in one sidewall (6) connected to the inner panel (16), the slot engaging the flap (32) when the box is erected.
