A Wood River Valley based hemp insulation manufacture plans to build a production facility in Jerome County along the interstate beginning this fall. Southern Idaho Economic Development said Hempitecture Inc., based in Sun Valley, intends to build a plant at the Northbridge Junction near the Interstate 84 and U.S. Highway 93 junction; a groundbreaking ceremony is set for early October. This is one of the first major business announcements made since a bill was signed into law earlier this year allowing the production and transportation of industrial hemp in Idaho.
