Generate shadows without trees: vegetable awnings, a new way to generate shadows in the city.

I found these kind of cool as an idea, as they can be added rather easily to existing cities and provide some greenery without taking up space, while providing shade:
This is totally dumb. I wouldn't want one attached to my building. How heavy are they? I'm guessing it doesn't snow there? How do you weed it when it invariably gets infested with weeds. The irrigation system is sure to break, how do you service that? This will look like absolute shit in a year.
I make canvas and awnings. Shade sails are almost always really stupid. Big bucks for very little bang. Most of the day you end up with a wee thong shadow halfway up the wall
