Environmental Growth Chambers set the standard for equipment in the controlled environment industry in 1953 with innovative greenhouse controls. With the demand for more controlled experiments in the late 1950s, EGC pioneered the emerging plant growth chamber market. In the early 1960s, we added controlled environment rooms to our product line.

EGC continues to introduce updated and enhanced technology to meet customer requirements. EGC has the world’s largest selection of controlled environment products and services.
