The panel (10) has a parallelepiped support frame (6) comprising structure elements e.g. gutters (7), in shape of semi-cylindrical channel with perforations (7b) containing a water supply duct (8). The gutters placed in front of a lower side and/or a lateral side of plant culture material includes a type (7-2) of gutter with its bottom turned toward exterior of the panel. Shape of the channel in cross section allows partial fitment of the bottom of a second type (7-1) of gutter with the first type of gutter. |
