Greenhouses for Transgenic and Non-Transgenic Crops
LOCATED ON THE SECOND FLOOR OF THE INSTITUTE FOR PLANT GENOMICS AND BIOTECHNOLOGY
The greenhouse space contains eight compartments 20 feet by 75 feet,
oriented North-South, separated by translucent double-walled panels. The
greenhouses for transgenic and non-transgenic crops use infrared-reflective
glass to reduce the heat load during the summer. Sodium lamps augment
natural lighting during the winter, to make up for cloudy days and to
extend the day length when desirable. Each compartment's average height
to the ceiling is 11 feet. A reverse osmosis water supply provides water
at 50 ppm total dissolved solids to each compartment. The cooling system
for seven compartments is evaporative; the eighth compartment's cooling
system is refrigerated for plants requiring even cooler temperatures.
This design allows a more or less normal daily fluctuation of light,
temperature and (relative) humidity. It protects the plants from extremes
that interfere harmfully with normal growth and development and totally
protects plants against rain, wind, insects, etc. Space is usable during
the entire year, assuring continuous production of plant materials of
differing climatic adaptation.
Greenhouses for Transgenic and Non-Transgenic Crops
LOCATED NEXT TO THE INSTITUTE FOR PLANT GENOMICS AND BIOTECHNOLOGY IN
THE GREENHOUSE ANNEX
![](pictures/annex2_sm.jpg)
The Greenhouse Annex opened for users on September
1, 2000. This facility consists of 25,232 square feet of greenhouse
space, and a headhouse of
16,473 square feet. The Headhouse contains an outside potting area, an
inside potting room, and a laboratory. The Greenhouse space contains four
compartments, one of which can be completely blacked out to simulate different
daylengths, and one has an outer opening that enables the benches inside
to slide out onto an existing frame for hardening off of plants, etc.
The greenhouses are computer controlled and each house is equipped with
reflective shading screens that open and close automatically to control
light intensity, temperature, and humidity. All greenhouses have metal
halide lamps for supplemental lighting. The Annex is designed to collect
rainwater for use in the greenhouses and all greenhouses have the capability
to use R.O. water, rainwater, or domestic water.
