Structural media
Structural media are growth medium "blocks" that are not loose, nor mats, but a substrate or fertile ground which provide minerals (Nitrogen, Phosphorus, Potassium, Magnesium, Calcium, Sulfur and some mineral nutrients in smaller quantities) needed for plants into a block that can be manufactured into various sizes, shapes and thicknesses. '''Every substrate recipe may differ in order to put forward a different features like: weight, withholding water, mineral needs of plants or sun exposure. This substrate can be hold by materials like : gabion with tarpaulin, gabion with rot-proof canvas or ceramic.''' These media have the advantage that they do not break down for 10 to 15 years, can be made to have a higher or lower water holding capacity depending on the plant selection for the wall, can have their pH and EC's customized to suit the plants, and are easily handled for maintenance and replacement. They are the most robust option for a living wall in both exterior and interior applications. They are also the best choice in areas where high-winds, seismic activity or heights need to be addressed in the design. Structural media are superior to the other media for their longevity and high-level of performance in a variety of circumstances. Depending on the installation, they do tend to be more expensive to install, but lower cost to maintain.

There is also some discussion involving "active" living walls. An active living wall actively pulls or forces air through the plants leaves, roots and growth medium of the wall and then into the building's HVAC system to be recirculated throughout the building. A problem with these systems is that building code still requires all the standard air filtration equipment that would have to be installed anyway, despite the living wall's installation. This means that active living walls do not improve air quality to the point that the installation of other air quality filtration systems can be removed to provide a cost-savings. Therefore, the added cost of design, planning and implementation of an active living wall is still in question. With further research and UL standards to support the air quality data from the living wall, building code may one day allow for our buildings to have their air filtered by plants.

The area of air quality and plants is continuing to be researched. The majority of the research cited is from NASA's studies performed in the 1970s and 1980s by B.C. Wolverton. There was also a study performed at the University of Guelph by Alan Darlington. Other research has shown the effect the plants have on the health of office workers..
