As Food Corps service member Ashley Turk navigates her way through a brand-new greenhouse in the courtyard at Waukon High School in the northeast corner of Iowa, she points to a robust supply of red and green lettuce leaves growing neatly in rows.
“It’s huge,” she says. “We cut it off and it just keeps growing.”
The greenhouse lettuce is among the offerings in the school’s salad bar. And students will soon be growing carrots, tomatoes and other vegetables, Turks says.
