-10°C to +45°C lights off

Additional options:

Height module, extending height by 500mm.


The Fitotron® HGC range uses a combination of different lamps to simulate a daylight spectrum. Through the use of high frequency fluorescent lamps, dimming of light intensity from 100% to 10% is standard. 'Dawn/dusk' is simulated by the addition of a high proportion of red light.

As an option, the height of the lamps can be adjusted using an external motor. This ensures that the growing conditions remain constant and the plants are not disturbed.

Metal halide lamp module with higher light intensity of 1000 ┬Ámols @ 500mm are available. The lamps are installed in a separate air-cooled lamp compartment, together with the UV light source.


Both horizontal and vertical airflow are standard. The plenum wall and floor design ensures a low air velocity whilst guaranteeing a high degree of temperature/humidity uniformity.

Low temperature

An optional low temperature module is available which is capable of a temperature of -10°C, ideal for simulation of night time frost conditions.
