This is a design for a wicking (or self watering) raised bed that minimizes cost. It uses standard wood pallets to create a space beneath the soil that is filled with water. Pipes filled with sand called “Soil Columns” wick water upward from the subterranean pool into the soil. The total cost for parts is around $230. Tools, soil, and plants are extra.
