Concordia has extended their growing season through the installation of a high tunnel, or hoop house, warmed by a solar air system. Last spring, Concordia received a grant to build a high tunnel. Further research showed a solar air system could extend the growing season even longer. Additional funding made it possible. Solar panels capture sun energy that heats air pumped through tile lines underneath the soil. This combination extends the growing season from Valentine’s Day to Thanksgiving.
