Urban Farmer Sells Affordable Fruits and Veggies, Envisions Skyscraper Farms

"You can grow just about anything, anywhere you want," Allen said.

On this farm, nothing goes to waste. Old food is used as animal feed or dumped into the compost pile. And Allen has an army of worms working for him. Millions of the red wiggly worms turn the compost into rich fertilizer and soil. "They are eating all the dead stuff and creating fertilizer, it's a living system" said Allen.

While Allen is already more than willing to tell people how to set up similar farms in their own communities, according to his son Jason, the inner city is the focus of Allen's attention.

"He focuses a lot on urban and inner cities," Jason said. "All you see is fast-food places. To have something like this in an inner city is real important."

That space is generally hard to come by in America's inner cities does not phase Allen; he simply plans to build vertical farm skyscrapers.

"I see food growing on rooftops," he said, lost in his vision of the future. "I see food growing on asphalt with compost."
