LFS Growth Chambers
The LFS Growth Chambers (Conviron PGR15 & GR48) are research-grade controlled-environment units designed for precise, uniform plant growth studies, located in the H.R. MacMillan Building (room 218) and are available for UBC wide bookings. The PGR15 is a tall, LED-lit reach-in chamber ideal for single-tier experiments with flexible temperature, light, and humidity control. The GR48 is a walk-in chamber offering spacious, high-intensity LED lighting and stable conditions suited for larger plant populations and reproducible long-term experiments. Both deliver reliable environmental consistency, adjustable light spectra, and tight climate control that researchers depend on for reproducible plant science results.
