Whoop it up for hoophouses: Being 'green' in the dead of winter

By Linda Lombardini

Today our guest writer is Clifford Dean Scholz, a green devotee for decades and a volunteer hoophouse builder.

We talk a lot these days about how “green” a person, business or group is, but personally I can’t think of anything greener than opening the door of a passive-solar hoophouse in February to find beds teeming with lush spinach, lettuce, and baby Asian greens.

Hoophouses are enclosures typically made of tubular steel and covered in translucent plastic. Heated only by winter sunshine, they help plants grow green and vibrant when most of Michigan is covered in snow.

But that’s not the only thing that makes them “green.” Since most of our winter vegetables are trucked in from hundreds or even thousands of miles away, using this cost-effective way to produce vitamin-packed veggies locally nets us significant energy savings.

Aware of this and the need to keep our food dollars in Michigan and develop the local food system in every way, Ann Arbor’s Selma Cafe launched an ambitious hoophouse-building initiative. Its purpose is to expand hoophouse-constructed local food capacity by harnessing the energy of hundreds of volunteers.

Lisa Gottlieb and Jeff McCabe are the cofounders of the cafe. “Hoophouses are very magical tools for creating food year-round in a northern climate,” says Jeff, who was supervising the builds at a recent hoophouse construction event. “In the summertime it’s like bringing Georgia to Michigan,” which benefits hot-season crops like tomatoes. “For cold season crops like spinach, it’s actually a better climate than you’ll find anywhere.”

Volunteers are occasionally wined-and-dined at day’s end, but they are always amply coffee-and-bageled to start the morning and fed a hearty lunch. Some describe the builds as an updated version of classic American barn-raisings. The community that forms and the illuminating conversations that accompany the work are as amazing as seeing these immense structures go up in a single day. Hoops have been installed on private, nonprofit, as well as publicly-controlled lands.


As a volunteer I’ve enjoyed the opportunity to roll up my sleeves and create a better future by helping local food producers come into the market. I may not be any greener, but I sure am getting a nice suntan!

I've always wondered.... how do you clear the snow off the top in the winter?

I have never built one of these hoop houses --but at a seminar about farming that I recently attended, they indicated that the snow does not really accumulate at the top because of the rounded shape. The way they build their hoop houses --It just slides off the plastic. I assume most of these are pretty similar.

Although ive not been involved in the hoop house building I can enthusistically recommend the Cafe Selma experience---both as a social and gastronomic event-- whose donations from their breakfasts go to this worthy project.

When Michigan decided to no longer allowed yard waste to be dumped into landfills they took away the methane gas needed to heat these hoop houses in the winter. Perhaps a community yard waste dump could be created to create a fuel source for winter gardening or maybe that would be too expensive.
