When Dennis and Danielle McClung bought a foreclosed home in Mesa, Ariz., in 2009, their new yard featured a broken, empty swimming pool. Instead of spending a small fortune to repair and fill it, Dennis had a far more prescient idea: He built a plastic cap over it and started growing things inside.
