Greenhouse: Facts and Figures

Space and Usage of the Biology Greenhouses

Greenhouses

The Biology greenhouse facility encompasses 6626 sq. ft under glass of which approximately 90% is occupied by plants. The "Morrill" house is a semicircular unit attached to the south end of the Morrill Science Center. A glass tunnel leads to four identical ranges, numbered 1 to 4, that are divided into East and West sections. The "Clark" house is located about 100 feet away from Morrill and is attached to Clark Hall.

What follows are sizes of specific areas in the various greenhouses. Also shown is the purpose for a particular space. "Class/Collection" is the category that includes plants grown for course demonstrations or lab materials, and for undergraduate research projects. The "Research" category indicates space that is primarily for faculty research, and is used by post docs, graduate students, and by visitors, technicians etc. from the faculty member's lab. "Service" refers to space dedicated to propagation, seed germination, and seedling growth. The actual uses and sizes of the areas given below vary somewhat from year to year.

Temperatures are regulated throughout the greenhouses by a thermostat-controlled venting system and by fan-powered evaporators in ranges #1 through #3, East and West. Lights of various intensities with programmable timers can be rigged over any bench. Range #4 (East and West sections) is devoted solely to tropical plants, and the Clark house is where plants are grown (e.g. alpines) that thrive under cooler conditions.

Growth Chambers

The Conviron growth chambers are housed in a 60' x 18' structure that is located opposite the four ranges. There are four walk-in chambers, eight smaller chambers, and one upright incubator. Almost all of the plants in these chambers are used for research, although some space is allocated for class use, especially when school is in session.

The growth chambers are controlled by a dedicated computer located in the head house. The environmental parameters are determined by the individual users, but the greenhouse manager is responsible for insuring that the conditions are maintained.
