No Space too Small for a Garden

Folks who live in apartments or who have very little space often decide they can't have a garden.  But no space is too small.  Pallet gardens and straw bale gardens are two options which produce a rewarding yield in a very small space.  Now there is hydroponic bottle farming in a window.  A recent NPR article gives the details.  Plastic water bottles and a few items from a pet store will provide salad greens and other vegetables in a sunny window.
