In 2009, when Dennis McClung and his wife bought their first home in Mesa, Ariz., they discovered that their backyard pool was so run-down that they’d need to spend thousands just to make it swimmable again.

Instead of restoring it, they converted the site into a garden that provides their family with food all year round while using 90 percent less water than a conventional farm.

The garden features a solar greenhouse that supports a tilapia pond, vine-grown grapes and tomatoes, other fruits and vegetables, and wildflowers. They also have a chicken coop for eggs and two pygmy goats that produce half a gallon of milk daily.

Dennis has subsequently turned the Garden Pool into a nonprofit organization that helps educate people about how to sustainably grow food.

On this episode of Dark Rye we’ll also visit with FarmTina, who grows her vegetables on a small New York rooftop; watch San Franciscan Heidi Kooy transform her backyard into a farm; and hear the folks at Gotham Greens discuss how they built the world’s first rooftop hydroponic greenhouse.
