The Growth Chamber Zone is currently equipped with 37 Conviron chambers of different sizes and capabilities. Units include standard chambers in 7, 15, and 36 ft² models.

All the chambers are equipped with magnetic refrigeration valves, atomizing spray nozzles, and provide precise control over temperature (+/- 0.1°C), relative humidity (+/- 3%), light intensity and photoperiod.

Chambers are individually controlled with microprocessors and computers which are connected to a central computer control system. All programming, data collection and maintenance planning for the individual chambers are managed through the central computer system. Automated telephone dialers contact Phytotron staff immediately whenever alarm conditions arise.

Over the past decade, the McGill University Phytotron has collaborated with industry partners in the testing and development of numerous controlled environment technologies including control computer hardware and software, novel lighting technologies and CO₂ control systems.
