Most of my adult life has been spent gardening in very small spaces -- a tiny urban yard, a deck, a porch, a windowsill or two. Only recently have I had the luxury of gardening on several acres. And I still feel a great fondness for tiny gardens. They're smart; they're what most people can manage; they make peak oil sense; they can be really stinking cute.
So when I came across Window Farms I spent hours browsing through the site. Window Farms is a non-profit based in New York City helping folks grow food in really innovative ways. Do check it out.
By the way, my own little low tech window farm is shown here: some tomato starts.
