Live in a city? Does the idea of growing your own food appeal to you? Do you have a window? Then you can create your own windowfarm. The awesome people at http://www.windowfarms.com/ have provided some DIY instructions on how to build your own under their Community section. It's so worth the effort if you truly love eating fresh produce— that you can say you "produced".
Be sure to share your version with Windowfarm people. They love that.
