Armstrong Research and Demonstration Farm
Weather often is one of the limiting factors for crop production in northern states. Growers in Iowa and other northern climatic regions are increasingly utilizing high tunnels to extend their growing season and increase fruit and vegetable production. In early spring and late fall, high tunnels help warm the air and soil and aid with crop growth and development. However, during summer, temperatures rise quickly in high tunnels and can detrimentally affect crop growth and development.
