The Greenhouse and Greenroof

The St. Olaf greenhouse and greenroof are located on the 4th floor of Regents Hall of Natural Sciences and Mathematics (RNS). The greenhouse contains 300+ species of plants and has space for student and class experiments. It is composed of five growing spaces of which two larger rooms support the general teaching collection and one smaller room houses cacti and succulents. Two rooms are dedicated to student and class projects and are used for a variety of purposes including growing seedlings for the STOGROW student farm. A headhouse provides space for pots, planting medium, and other supplies. Water for the greenhouse comes from a 3000 gallon cistern that collects rainwater from the central atrium roof of RNS. Student workers play a large role maintaining and caring for the plants in the greenhouse.
