Introduction
Conditions in controlled environment plant growth rooms and chambers should be reported in detail for comparison of results and duplication of experiments. The minimum guidelines presented here, including additional explanation and a reporting example, should help meet these aims, indicating a required, minimum amount of information that should be reported. They may also highlight parameters that could be important, but that may not have been considered for measurement. Three different publications are available:

1. The Minimum Guidelines Brochure is designed to be printed in color on both sides of a single sheet of paper (either A4 or Letter size) and folded twice into a convenient leaflet. One of the recommended distribution methods is to place several copies of the brochure in a container located below the small Minimum Guidelines Poster that is mounted at a prominent location in a Controlled Environment facility.

2. The small Minimum Guidelines Poster is designed to be printed in color on one side of a single sheet of paper (either A3 or Ledger size) and laminated. A recommended display method is a prominent location in a Controlled Environment facility so users will encounter the poster as they make use of the growth rooms and chambers.

3. The large Minimum Guidelines Poster is designed to be printed in color on one side of a single sheet of paper (poster size; e.g., 914 by 1168 mm or approximately 36 by 46 inches). This laminated poster is designed to be displayed at a scientific meeting so researchers can review the guidelines recommended by the Committee. It is recommended that the display of the large Minimum Guidelines Poster be accompanied by a stack of Minimum Guidelines Brochures for interested researchers to take with them. Each of the three sponsoring organizations has a single copy for loan, complete with an abstract written by the International Committee for Controlled Environment Guidelines (UK CEUG contact: Julian Franklin, julian.franklin@bbsrc.ac.uk; NCR-101 contact: Mark van Iersel, mvanier@uga.edu; ACEWG contact: Paul Austin, PAustin@hortresearch.co.nz). If a meeting organizer requires an abstract, please use the International Committee’s abstract.
