When researchers need to study plants in particular environment, they create the conditions they require in the phytotrons at the K.C. Irving Environmental Science Centre. This exceptional facility's controlled atmosphere allows precise manipulation of temperature (±0.5ºc), humidity (±5% RH), atmospheric CO2 (±10 ppm), and the simulation of pollutants in precipitation. Rather than conventional vents and exhaust fans, the glasshouse is cooled geothermally. This allows a greater degree of temperature and humidity control and provides control over the composition of the atmosphere. The air handling system has the capacity to scrub ethylene, nitrous oxides, and other contaminants, including fungi, from the atmosphere and precisely control fresh air exchange.
