As far as the construction system is concerned, it is simply based on a structure made of metal material which is compact, self-supporting or connected to the building by means of special clamps according to requirements and type. A PVC sheet is applied to the structure, above which is placed a felt board covering. In essence, a technical fabric is created in which the seeds are introduced, or the essences already born and developed are buried, taking as a reference a density of about thirty plants per square meter. The vegetation is bathed and watered through a completely automated irrigation device responsible for a homogeneous water diffusion: this plant is completely obscured from view, so that it does not create disturbances from an aesthetic point of view. There are some systems, on the other hand, that use modular panels already grassed, of more or less large dimensions, which are already ready to be allocated on the aluminum structure. As far as maintenance is concerned, it must be carried out at least twice a year (on average; much depends on the species selected and on the external climate), also taking into account the desired effect (in practice, the length of the 'grass). In any case, automated fertilization systems can be used to enrich the water with nutrients, also combining anti-parasites and fungicides.The species
Regarding tree species suitable for the realization of vertical gardens, they can be distinguished in micro-spa species and in macro-thermal species. The first are indicated especially for areas where temperatures are between fifteen and twenty-five degrees: they grow mainly in spring and autumn, and suffer quite clearly from the heat, salty winds and drought. This is the case, for example, of festuca rubra, lolium perenne, festuca arundinacea and poa pratensis. Macro-spa species, on the other hand, are suitable for warm climates, therefore suffering sub-zero temperatures: in the presence of cold conditions, they enter vegetative rest and almost completely lose their green color. It is the case, for example, of zoysie, paspalum vaginatum, cynodon dactylon and stenotaphrum secundatum, species that require a temperature of growth between twenty-five and thirty-two degrees. The creation of vertical gardens, as mentioned, brings numerous benefits, as well as aesthetic, practical and functional. A façade covered with vegetation, in fact, can enjoy the thermal regulation guaranteed by the transpiration of the plants, which allows to make the air fresher, while the circulation of the air itself is favored by the interspace. Important obstacle to the spread of fire in case of fires, the vertical green allows, among other things, to purify and filter polluting atmospheric agents, purifying the air through the production of oxygen and the absorption of carbon dioxide. Finally, the noise reduction made possible by the absorption of sound waves by the plant mass, which also contributes to the containment of the reverberation, should not be underestimated. But a vertical garden also translates into economic advantages: not only because a building characterized by greenery is inevitably enhanced, but also because the same green can be used to create logos or advertising writings, playing on the different shades of color or on the different lengths of the 'grass. The vertical gardens, for the moment, are widespread especially in the cities of Northern Europe (also for the interiors, or in terraces and balconies where it is possible to create vertical gardens).
Vertical realization gardens: DIY vertical green
Anyone wishing to recreate it at home will need a plastic tube with a diameter of one centimeter, a few plastic pots, a plastic box and some wire. Under each jar two holes will have to be made, and the same thing will have to be done for the plastic box. The jars, fixed to the panel, will be used to grow the seedlings, which will be irrigated through the plastic tube. The pipe, in turn, will have to be pierced in different points, so that the running water that will be made to flow inside it can reach the ground and the plants in the panel, hanging on the wall with the wire.
