Greenhouses

The Abelson Greenhouse is a 4000 square foot rooftop greenhouse occupying the 7^th floor of Abelson Hall. Built in 1985, it is divided into nine independently controlled compartments used for instruction and research. One large compartment (2400 sq. ft.) houses the tropical portion of the instructional plant collection. Eight independent small rooms (90 sq. ft. of growing space each) are used predominantly for research. Recent renovations in 2025 included an improved Argus automated environmental control system that allows for data collection and remote access, as well as high intensity, full spectrum, dimmable LED lighting and new automated shade cloth.

The Steffen Center Greenhouse was built in 1995 and is 3000 square feet. It is located at the E.H. Steffen Center about 1.5 miles from the center of the WSU Pullman campus. It is divided into 4 independently controlled compartments that have 450 square feet of growing space each and is used predominantly for research.  2025 renovations included new polycarbonate roof and siding, high intensity, full spectrum, dimmable LED and HPS lights, as well as an Argus automated control system with data collection and remote access. A 680 square foot headhouse allows for space to process plant material and store supplies.
