As demand for fresh, local food intensifies, growers are getting more serious about providing produce outside the growing season. Home gardeners can grow greens at home during the winter months too. Chris Currey is an assistant professor of horticulture at Iowa State University, and he says hydroponic gardening is becoming more popular.
"For current producers, there are a couple of reasons why it's popular. We can recycle the water," he says. "We're often collecting water, treating it, and applying it back to the crop. Compared to an open field produced lettuce crop, you use far less water."
During this hour of Talk of Iowa, host Charity Nebbe talks with Currey and horticulture expert Richard Jauron and answer listener questions.
