The Donald Danforth Plant Science Center Plant Growth Facility (PGF) is a state-of-the-art facility built for research product development. The PGF provides its users with expert horticultural services as well as a variety of plant growth spaces and climates.

The PGF complex consists of: 

  • Three greenhouses ranges (43 bays) providing 54,130 total sq. ft. of active growth space with houses of various sizes and functional capabilities. Select houses are equipped with air-conditioning, in-floor heating, high intensity lighting, auto-irrigation systems, and adjustable light canopies for more precise lighting control. PGF users are free to utilize any of the three potting rooms as well as seed processing, soils handling, and general work areas.

  • A total of 84 plant growth spaces, including reach-in chambers (48) and walk-in growth rooms (36).  All chambers offer variable lighting, temperature, and humidity control. Advanced chamber features include carbon dioxide supplementation or scrubbing, high light intensity (up to 1000 µmol/m2/s), low- and high-temperature control functions (-10°C to 50°C), and spectral control using LED technology.
  • The expert PGF staff members provide 365 days per year care for all plants so that researchers are able to focus on research goals rather than plant care. Please see our Services for more information.
