A system comprising a first three-dimensional structure (1) that is filled with a substrate, a hydrophilic fabric (3) that closes the sides and the base of the first three-dimensional structure (1), a second three-dimensional structure (2) secured to the assembly formed by the first three-dimensional structure (1) and the hydrophilic fabric (3) covering the base and sides of the first three-dimensional structure, resulting in a planar system which has high substrate ventilation, is modular, made of three-dimensional structures that do not deform, can be suspended when used, can be covered with different materials and attachments, and, most importantly, promotes contact between the rhizosphere and the air and therefore promotes its detoxification and biofiltration function.
