“Are your shoes clean?” Julie Hoene wants to know as she greets a visitor to Julie’s Farm Fresh, the family farm near Elizabethtown. It’s a drab, gray day with periods of drizzle interspersed with more insistent rain. But inside Hoene’s greenhouse, it is comfortably warm and humid, enough to fog up a camera lens. Welcome to her world. Hoene describes herself as a stay-at-home mom, but she spends much of her time in the greenhouse, where she grows lettuce and sometimes herbs. She uses hydroponics, a system that involves growing plants without dirt, delivering nutrients via a computer-controlled watering system. And Hoene is serious when she asks about the cleanliness of a visitor’s shoes. Julie’s Farm Fresh is registered with the state Board of Health and Bartholomew County Board of Health; she is also a member of the Indiana Growers Association. She adheres strictly to a food safety plan. Dirty shoes do more than track in mud and make a mess; they also could carry germs that trigger disease, a threat to the plants and consumers. So strict are the rules that Hoene follows that if a lettuce leaf falls on the washed and sanitized floor during harvesting, it will be deemed unmarketable and tossed out. “It outlines what we do,”

Hoene said, explaining the safety plan. “If someone is sick, they are not allowed to be in here. … We have livestock (and wear) special clothes and shoes when we come in here.” Hoene has bachelor’s and master’s degrees in education and taught in Seymour schools for several years. But after her second daughter was born, she decided to abandon the classroom for the greenhouse. She comes by her green thumb naturally. Growing up, her family had a big garden; canning and freezing were part of everyday life. Her husband, Ben, works full time at Premier Cos. but Julie’s Farm Fresh has always farmed on the side.

Road 650S, Julie Hoene said they have Elizabethtown long had an interest in hy812-603-2744 droponics, helped along by a visit years ago to a greenhouse where tomatoes were grown hydroponically. What really tripped the trigger was when they attended a workshop several years ago. “We started planting in December 2015,” Hoene said. “Our first harvest was about a year ago.” The greenhouse, essentially two layers of plastic separated by a layer of air and stretched over a hoop-like frame, is self-sustained and environmentally friendly. About every aspect of its operation is computer-controlled. A vent system opens automatically to let in CO2. A fan blowing air over water tumbling down an artificial wall (called a wet wall) serves as an air conditioner. Heavy netting and a unit called an insect exclusion, essentially a fan blowing down a “curtain” of air, are intended to keep bugs out. “Insects don’t come through that blanket of air coming down,” she explained. Hoene grows a type of lettuce called Lollo, which has a frilly green leaf and is often used on sandwiches. She also grows a spring mix and a small amount of bibb. Lettuce plants begin life as seeds that are (Continues on page 2)
