DENVER -- Across the street from the Purina Dog Chow plant, next to the railroad tracks in an old Denver neighborhood, you'll find some of the freshest produce in Colorado.
Twenty-thousand square feet, all inside and covered, it's the Growhaus Indoor Farm. "In that we're growing lots of salad greens, lettuce, cilantro, spinach, kale...," says Director of Operations Adam Brock.
Located in the historic neighborhood of Elyria Swansea, Growhaus is utilizing the very modern technology of hydroponics.
"Hydroponics is a really efficient growing technique where you're raising a bunch of plants with a nutrient solution and that same water just recirculates around and around," says Brock.
In other words, all the plants here are grown using no soil whatsoever.
Brock says no soil means no pesticides, and "Because it's a recirculating system and we pack the plants in really close, we're using about one tenth of the water as conventional agriculture growing it in soil."
The savings are passed along to customers who can buy these fresh veggies for pennies on the dollar.
That's an idea that can really take root.
