bit-of-green site has now expired, so no instructions on how to make this vertical garden or ability to make the picture larger...there doesn't seem to be another non-pinterest reference on the web. Does anyone have any more info on what the backing.
Vertical Succulent Garden by floragrubb: 20 x 20" panels with 45 slanted cells to support planats and soil when mounted vertically. The unit in the picture is made of 6 panels, each $79. Now, if I could only figure out how to make the panels myself..
