A “high tunnel” greenhouse is essentially heavyduty plastic sheeting stretched over a frame shaped like half a tunnel.  High tunnels cost less than traditional greenhouses, but they work well too.

Tucker County High School has three greenhouses, one a high tunnel. In the spring, students raise the salad for the school cafeteria, plus local restaurants. Local people stop and buy vegetable seedlings the students grow.

Agriculture teacher Terry Houser gives students starter plants for home gardens. “Our goal is to get the community gardening again,” he said. “The kids learn to garden at school, then they go home and bug their parents to plant a garden.”

He encourages students who want to grow food as a business. “We’re building a business component into the program, and the program give students a built-in lab,” he said.

A high tunnel greenhouse is comparatively easy to create, he said. He teaches students to build an effective temporary high tunnel with little more than tubing and plastic sheeting.

For the past few years, several students have made thousands of dollars in summer, raising vegetables in fields and high tunnels, then selling at farmers markets and through the Farm to School program.

A high tunnel for school or home will cost as little as $2,000 or as much as $10,000, depending on the size, the amount of volunteer labor, and the extras.

High tunnel in the community: A community high tunnel can feed other community projects: In Williamson, Southern Community and Technical Community College students helped put up two high tunnels across from the Williamson senior citizen high rise, next to the community garden. The high tunnels help feed the farmers market year-round.

“A high tunnel could feed the Senior Center or the food pantry,” said Jenny Sue Hudson, director of the Mingo Diabetes Coalition. “There are lots of potential uses.”
