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.
