A modular wall system and a modular wall

A modular wall system comprising a plurality of elongated wall panels disposed on one another, a plant bedding material tile, a seed/plant cup, a board, and an irrigation pipe, wherein:

• the elongated wall panels comprise a vertical wall, a top flange and a bottom flange;
• the fluid emitting irrigation pipe is disposed on and/or couples to at least one of the top and bottom flanges of an elongated wall panel;
• the board comprises at least one opening configured to receive a seed/plant cup, and wherein the board is coupled to at least one of the flanges of the elongated wall panel, thereby forming a wall panel interior;
• the plant bedding material tile is configured to be coupled to an interior vertical wall portion of the elongated wall panel and/or to an interior wall portion of the board;
• the seed/plant cup is configured to be inserted from the outside through the at least one opening in the board to thereby be partially disposed inside a cup bedding material opening of the plant bedding material tile;
• and wherein
• once irrigated by a fluid supply provided by the fluid emitting irrigation pipe, a seed/plant in the seed/plant cup disposed inside the plant bedding material tile is configured to grow roots into the plant bedding material tile and grow a canopy extending from an exterior of the board.
