Vertical Gardens can be realised in various technical ways, depending on your wishes. All structures have a minimum lifespan of 10 years and are easy to maintain. The wall’s maintenance is similar to the regular maintenance of a houseplant. All vertical surfaces, large or small, can be covered in plants. The sky is the limit.

Eco-system
For larger projects, the used water is collected and reused in full. This is a closed system. The drain water is reconditioned every cycle, and the evaporated amount of water is constantly replenished, preferably with rain water. This is a slightly more technical system, which also requires a separate structural strength calculation on account of its size. It comprises a unit with an LDPE wallboard with a thickness of 1 cm. A constant water flow, as in a single hydroponic system, supplies water and nutrition.

Choice of plants:
With both systems, it is vital to select the right plants in order to prevent bare spots from emerging in only a couple of months’ time just because the plants fail to grow in their new location.

There can be many reasons for this, such as:
• Too much or too little sun
• Temperatures that are too high or too low
• Too dry or too wet
• Too windy (leaf necrosis) (drying out)
• Humidity
• Draught (plant diseases)
• Acid level of the soil (pH)
• Salts
• Seasonal effects
