It's not your conventional looking farm. A hydroponic growing system at Urban Produce has trays of organic produce stacked vertically, which rise high up in a building in Irvine.
There are seven different leafy vegetables, from bok choy to wheat grass, totaling about 16 acres worth of produce. The hydroponic garden uses 90-percent less water, according to Urban Produce CEO Ed Horton.
Where the water comes from is even more uncommon.
"It's actually taking the air and converting that into water," Horton said, pointing to a large commercial unit. "This is actually a dehumidifier, so it actually pulls the humidity out of the air so we water the plants, the plants create humidity, we pull that back out of the air."
