High Density Vertical Garden (HDVG)

What in the world is a high density vertical garden, you ask? Well, thanks for asking!

I just came across the term and idea, and I like it. Here's what someone else wrote about vertical gardens:

In Victorian times, houses were very narrow, multi-storied, and had a small "footprint" on the land. This left more land for private gardening, and commons, among other things. Then came the 1960s, and "ranch style" homes, with half-acre grass covered lots. By the 1970's anyone with a vegetable garden in a suburban or city back yard were "hippies," "weird," or "old fashioned."
The 1990's saw the boom of Mega-Mansions on postage stamp sized lots, weekly lawn-care crew visits, and still little vegetable gardening on a respectable scale, regardless of whether one lives in the city or the suburbs. Now we have an oil crisis overlain with a salmonella crisis: both of which the US Federal government seems incapable of dealing with. Vertical gardening might help change that.

Vertical gradens are said to grow vegetables and other foods much more efficiently and with greater food value than in agricultural field conditions.

Other claims are that vertical gardens produce approximately 20 times the normal production volume for field crops; require 5% of the normal water requirements for field crops; function in a variety of environments, such as urban, suburban and countryside; do not use herbicides or pesticides; save significant operating and capital costs over field agriculture; and, will drastically reduce transportation costs to market resulting in further savings, higher quality and fresher foods on delivery, and less transportation pollution.

Maybe worth a try, huh? Here's a visual:
