After quite a bit of research, I found the simplest method was pioneered by a French botanist by the name of Patrick Blanc. He calls it Le Mur Vegetal, and its really quite a simple solution. He has built several Vertical Gardens throughout the world, and a few people have adapted his method to create their own. Before I began, I sat down and planned in detail on Sketchup how to build it. If you're interested in building your own one, this is a short video I made to show the steps involved in making your own green wall.
