The gutter garden is less than $20 to make and everything is available at your local home improvement center. You'll need: a rain gutter, two end caps, a few brackets, a bag of dirt, and some seeds. Hang the gutter, drill some small holes every few inches for drainage, fill with dirt, and plant.
Most shallow rooting vegetables do very well in the gutter garden. Lettuces, radishes, parmex carrots, herbs, strawberries, etc.
