Rothamsted Research (RRES) requires four High Specification Plant Growth Chambers each with a growing area of at least 1.45 square metres, with accurate and reproducible controlled environments for studies of arable and horticultural crops. These cabinets are required for research on plant stress and hence require good environmental control at the extremes of temperature, light and humidity.

For the proposed research, accurate control of light intensity ( 0 to 1 000 mol(PAR)), far red/red ratio, day length, temperature (-10 to 45°C), relative humidity (40 to 85 %), carbon dioxide level (0 to 2 000 ppm) and airflow is needed.
