McClung said his wife grew up on a farm in rural Ohio. But most of the knowledge to create the garden came from Internet research and about a decade at his job at Home Depot, where he helped other families bring their ideas to life.
When he and his wife bought their home, McClung, who now works as a Web designer, said his own turn had arrived.
"It was kind of like, I finally have my own house after working at Home Depot forever and I can't wait to fix it," he said. "I was very gung ho."
Even the McClungs' 4-year-old son enjoys working in the garden.
"He really loved when we first started picking vegetables. He thought it was the most amazing thing," McClung said. "He's really in awe. I think he appreciates food more."
The family works together in the garden every day of the week and they've even become something of a local attraction.
Tour groups of 10 to 40 people visit the McClung home regularly to learn about their organic garden and pay a suggested donation of $5 a person. A local sustainable gardening group recently made the garden pool the star destination on its tour of sustainable Arizona homes, McClung said.
"Our family made it a goal to be as self-sufficient as we can by 2012. This was just another step for us," he said. "We wanted to share what we have. If people take a couple of concepts and practice them that's great."
