SIOUX FALLS, S.D. (AP) — South Dakota State University is looking to build a new $3.8 million greenhouse complex that will replace old, run-down space with a research-quality facility with stricter environmental controls.

The 11,000 square feet of new greenhouses will replace ones that are “held together with masking tape or duct tape and wire,” are difficult to keep heated and have lighting issues, said David Graper, an SDSU professor of horticulture.
