Area of Application: Plant Growth
Product Type: Plant Growth and Insect Research - Special Projects


Weiss Technik UK installed six customised Fitotron® Plant Growth Rooms at Syngenta, United Kingdom.

Syngenta is a world-leading agribusiness committed to sustainable agriculture through innovative research and technology. The organisation is a market leader in crop protection and ranks third in the high value commercial seeds market.

The customised rooms are used for research into weed control and are of two differing types. The rooms have the following capabilities:

Weed Control Type 1

  • Temperature range from +5°C to +35°C (lights on/off)
  • Humidity range from:
    85%RH to 95%RH at +2°C
    40%RH to 95%RH at +35°C
  • Uniform horizontal airflow
  • Containment level 2 (positive/negative pressurisation, trapped drain, filtration of air exchange)
  • Easily cleaned Epoxy floor
  • High lighting at 1200 µmol m-2s-1 at 350mm using T5 fluorescents
  • Dimmable lighting in the range 10% - 100%
  • Temperature controlled individual lampboxes
  • Lighting uniformity of ±10% over 75% of growing area
  • Fully programmable ramp/dwell times for temperature, humidity and lighting
  • Remote PC data logging and programming including emial notifications of alarms
  • Temperature and humidity extremes maintained with four to six air changes per hour
  • Chilled water cooling using three chillers, each rated at 50% duty, to provide back-up facility
  • Comprehensive acceptance testing
