Abstract: A green wall planting module has a rear wall, two side walls and a top and bottom wall, the top wall having a concave shape for receiving within its cross section a bottom wall of a green wall planting module mounted approximately one to four millimeters above it on a grid wall structure to suppress splashing and retain rain water. The grid wall structure comprises horizontal rods associated with a vertical wall structure of, for example, a building. The top wall of a lower mounted green wall module comprises an integral slot adapted to receive a horizontal irrigation pipe or hose which may lie horizontally in and longitudinally along the slot when the green wall modular apparatus is mounted to the grid wall. Tapered louvers are provided within the green wall planting module slanting upward from the rear wall at a predetermined angle within the module so as to collect and retain water as does the bottom concave wall of the apparatus.
