Lauren Elder designed this vertical growing system in response to the needs of folks living on steep hillsides in Caracas, Venezuela. Although they had just tiny hardscaped patios they still wanted to be able to grow food. By suspending cheap, colorful plastic dishpans in welded wire columns, a significant amount of growing space could be created. Each pan had holes in the bottom so when watered at the top the pans would allow the water to drip from one to another. The wire grid was large enough to allow reaching a hand in to harvest. When lined up next to each other the stacks create a festive "screen".
