Provided is a modular growing panel system for attaching vegetation to a surface of a structure. In one aspect, the modular growing panel system includes a growing substrate with a plurality of layers formed into a tile that is rigid and self-supportive of vegetation being grown in the growing substrate. A binder attaches one or more of the tiles to each other and forming the modular growing panel system. In another aspect, the modular growing panel system includes a growing substrate with a plurality of layers formed into a tile that is rigid and self-supportive of vegetation being grown in the growing substrate. A framework for holding and attaching one or more tiles to the structure includes an upper channel having a slot that corresponds to the depth of the tile and a lower channel also having a slot corresponding to the depth of the tile.
