Our plant growth facilities include a large number of modern air-conditioned greenhouses, many with sophisticated filter-air systems, covering more than 75,602 assignable square feet. Several lathhouses for shaded outdoor plantings and an extensive screenhouse for insect-free culture are also available. Headhouse facilities include potting and service areas plus a large number of controlled environment growth chambers and temperature-controlled tanks for plant growth. Support personnel provide cultural care, pest management, and maintenance of the entire greenhouse facility. Extensive farmland is available as well, on campus and elsewhere. The Department has several shared Arabidopsis growth rooms totaling about 2,600 square feet of growth space and several small greenhouses designed for year-round Arabidopsis growth.
