i've been in some other cities and have seen places where they had vertical gardens, literally gardens done on the side of a wall. by far the most interesting i've seen was in saigon, an entire block had a wall that was just planters lined up in a grid, with the pots coming out at maybe a 45 degree angle ...and i find it interesting because the concept is so simple, what they did could be fairly easy to build yourself, but i figured someone must make something like it somewhere... everything i've been finding are these really fancy "modules" that are somewhat high design and usually not inexpensive. this could be done by building a criss cross of supports that hold regular pots.

i've been searching online and elsewhere for something similar but haven't had a ton of luck. today i was reading the dwell earth day edition (free online @

i've also saw an article in the NYT or somethign somewhere, where someone built a daisy-chained top to bottom planter whereby they used plastic bottles that kind of fit into one another vertically, so you watered from the top and it filtered down to the bottom. this was an indoor inside a window concept that was kinda cool.
http://www.greenroofs.com/archives/green_walls.htm is kind of an interesting article on the matter too
but does anyone else have suggestions for ways to do vertical planters on a wall? are there any publicly viewable gardens done this way anywhere? where i'm at now is a bit limited on planter space, but i have two walls that get decent sun that i'd like to somehow take advantage of ... it would be more ideal if whatever it is was a large rigid grid and each planter didn't need screwed in like the wally does.
