<p>The decoration and irrigation system (1) is for plants in boxes mounted on vertical walls and also aiding noise insulation. The plant-growing and irrigation operation is carried out in a number of layers. The heating effect of the wall can be reduced by insulating layers of rubber, plastics, or water-storing mats, and plants can be grown in a mixture of topsoil and peat, while the water is stored in gravel, the latter being separated from the vegetation by a filter mat. The different layers of material can be accommodated in removable baskets.</p> |
