Harr Family Farms has operated a booth at the Soulard Farmers Market in St Louis since 1925. The farm is co-located with the Harr family’s other long-running businesses, Wall-Vern Products, a wholesale door supplier, and Thermo Door Company. In 2017 the Harr family installed 160 KW worth of solar energy at their East Carondelet location, enough to offset almost 100% of their annual electricity usage with solar energy.
