The Garden Tower Project on KickStarter opens with "Composting + 50 Plants = Fresh Food Anywhere".
Not to be confused with the Tower Garden, the Garden Tower uses compost as the growing medium, where the Tower Garden uses an aeroponic system (air and water as the growing medium). A compost tube runs p the center of the Garden Tower. From the Garden Tower FAQ page:
The Tower Garden (not to be confused with the Garden Tower) is a vertical garden that uses a 5' tall aeroponic system to grow up to 20 plants in less time than it takes in soil.
On the What Can I Grow section of their website, they list fruits and vegetables like Peas, Cucumbers, Lettuce, Squash, Strawberries, and Tomatoes; Herbs like Basil, Cilatntro, Oregano, Lemon Grass, and many types of flowers.
