-Unlike the roofgardening industry, there are no accepted standards for vertical gardens or green wall infrastructure and this has resulted in some interesting customised methods. One of the leading designers of vertical gardens is Patrick Blanc. Using a scientific and deeply researched process, Patrick conducts studies in tropical areas, primarily on “understory” plants which receive minimal sunlight beneath the rainforest canopy, and can thus be presumed to grow in humid indoor areas where sunlight is limited. He figures out which species will thrive in the environment for which he’s commissioned to design, then configures the garden such that it’s self-sufficient, requiring only quarterly maintenance. The Vertical Garden in this case is composed of three parts: a metal frame, a PVC layer and felt. There is no soil. The metal frame is hung on a wall or can be self-standing. It provides an air layer acting as a very efficient thermic and phonic isolation system. A 1cm thick PVC sheet is then riveted on the metal frame. This layer brings rigidity to the whole structure and makes it waterproof. After that comes a felt layer made of polyamide that is stapled on the PVC. This felt is corrosion-resistant and its high capillarity allows a homogeneous water distribution. The roots are now growing on this felt. Watering is provided from the top with the tap water being supplemented with nutrients. The process of watering and fertilisation is automated. The whole weight of the ‘Vertical Garden’, including plants and metal frame, is lower than 30 kg per square meter.((http://www.pingmag.jp/2006/12/08/vertical-garden-the-art-of-organic-architecture/))((http://www.worldchanging.com/archives/005734.html))
