The Climatron is a greenhouse enclosed in a geodesic dome that is part of the Missouri Botanical Garden in St. Louis. Initiated by then Garden director Frits W. Went, the dome is the world's first completely air-conditioned greenhouse and the first geodesic dome to be enclosed in rigid Plexiglass (Perspex) panels. Completed in 1960, it was designed by T. C. Howard, of Synergetics, Inc., Raleigh, North Carolina. The broad climatic range within the dome, which recreates a lowland rain forest, is achieved by sophisticated climate controls without using interior partitions.
