Just completed my first vertical gardening project in which I utilized the Bright Green USA modular system, and I must say, I will only use this system for large vertical gardens from now on. The solution consists of 20" X 20" modules, each containing 45 slanted cells. Basically, there is no real limit to how many modules you can combine, I started with a modest installation that is 60" wide X 40" deep. I have seen pictures of entire sides of commercial buildings and homes covered in a mosaic of plants using this system.
I installed a drip irrigation system for this living wall, and everything about this project exceeded my expectations. I am going to do something really large scale with this system, soon! I wish I would have made this installation larger, but there's always the next project.... Here's a detail shot.
This living wall is on a North-facing wall, under an arbor in complete shade. The plantings primarily consist of ferns, succulents, ivy, selaginella, ficus and "splash."
I simply mounted 2 X 4s onto the block wall, then secured the mounting hardware which supports the panels.
Planting in progress, giving you an idea of the form of the modules, and the slanted cells.
