Thaylen Harrison, an employee of Performance ECM, bends a pipe to hold wires on the new greenhouse at Smith College. The college’s new research greenhouse, which is expected to be operable by the end of October, will be used by students in the plant physiology lab and other plant courses, providing space to do plant biology research in a controlled environment. It will also be a space for students to run their own experiments, getting hands-on lab experience. STAFF PHOTO/CAROL LOLLIS
