Gordon College opens new, high-tech greenhouse on Wenham campus.

When seen under moonlight, Gordon’s Ken Olsen Science Center (KOSC) can sometimes appear to glow a soft hue of pink through it's third floor skylights. The pink glow emanates from a research greenhouse that recently opened on campus—and plays a vital role in the work that goes on inside. In the new greenhouse, a combination of red and blue wavelengths supply most of the light these plants need to grow. These lights use significantly less energy than traditional white greenhouse lamps, which use all ROYGBIV wavelengths when, in actuality, only RB is needed for plant growth. These lights also give off far less heat, allowing them to be placed much closer to the plants themselves, which means the plants can absorb nutrients faster and more effectively.

The greenhouse has been in what Dr. Jennifer Noseworthy, assistant professor of Biology & Director of the Scientific Enterprise Department advising, calls a “testing phase" in 2017. To test the greenhouse’s environmental capabilities, Dr. Noseworthy has been growing a crop of poinsettias, which are high maintenance plants that require lots of environmental control in order to grow optimally. There are two distinct climate zones in the L-shaped greenhouse space; the smaller of the two is a tropical zone and the larger is a temperate zone. Each zone is equipped with tools that control the temperature, humidity and light. And an outside weather system connected to the greenhouse allows the department to take advantage of weather conditions outside of KOSC on days that can complement tropical and temperate climates.

The benefits to such a high-tech greenhouse on Boston's North Shore are substantial "in research, teaching and outreach,” Dr. Greg Keller, professor of Biology and current Fulbright Scholar for the Arctic Initiative. “With this technology scholars can manipulate the smallest variables to see their effects on specific species of plants that may be valuable economically or ecologically.”

With classes about to start for the spring semester, the greenhouse is ready to serve as a space where classes can be held for majors and non-majors alike, starting with Dr. Noseworthy’s 300-level Sustainable Horticulture course and Dr. Ming Zheng’s (biology) Medicinal Botany courses.

There are also plans to develop a botany lab in the near future at Gordon College, which will sit adjacent to the greenhouse. The botany lab will allow students and faculty to set up experiments, organize lab materials and, as Keller explains, open up opportunities to “study topics like medicinal botany to understand how compounds produced by plants might be used in medical treatments or sustainable horticulture to focus on
greater crop production.”
