Guidelines for Measuring and Reporting Environmental Parameters for Plant Experiments in Controlled Environments

Prepared by the
International Committee for Controlled Environment Guidelines (ICCEG).

The ICCEG is sponsored by the UK Controlled Environment Users’ Group (UK-CEUG), the North American Committee on Controlled Environment Technology and Use (NCERA-101), and the Australasian Controlled Environment Working Group (ACEWG). The committee publishes guidelines  for measuring and reporting environmental parameters for experiments in controlled environments as a joint effort of these three organizations.


Conditions in controlled environment plant growth rooms & chambers, greenhouses and tissue culture facilities should be reported in detail to allow for comparison of results and duplication of experiments. The guidelines presented here, including additional explanations and reporting examples, should help meet these aims and describe what is deemed the minimum required amount of information that should be gathered and reported. They also highlight parameters that could be important, but that may not have been considered for measurement and reporting.
