The Garden Tower Project #Container_gardening
The Garden Tower grows plants vertically, enabling you to grow 50 plants in a very small space -- the ultimate square foot garden with integrated composting! Most container gardens only allow planting on the top. The Garden Tower has 45 openings around the outside and space for up to 5 taller plants on top, with a worm tower in the center.
You add kitchen scraps into the center tower which creates a compost tea that drips out the bottom which you add back into the plants. Each hole can grow a different plant. 50 plants in 4 sq. ft.- Strawberries, lettuce, herbs, flowers... endless possibilities! Look at ALL the combinations!
This is a great idea worth checking out. http://www.gardentowerproject.com/index.php/resources/setup
