Many people who live in apartments, especially those in big cities, know the struggles of finding fresh foods (and I'm not talking about the "fresh" produce that's traveled hundreds of miles to be sold in grocery stores). Many neighborhoods in big cities are literally food deserts, with no nearby farms and no access to backyard gardens in which to grow food.
New Yorkers Britta Riley and Maya Nayak, two serious green thumbs who wanted to start growing their own food, started a movement called "window farming" and it's catching on fast with apartment dwellers and inner city folks all over the world. Basically, window farms are vertical columns of plants that can grow vegetables and herbs harnessing the power of the sun (and a little electricity) and without using any soil. (See the video below.)
