Climate rooms for plant growth tests (Seed breeding)

To carry out growth tests, various climate conditions need to carefully and as desired be created.  Plant growth rooms are therefore configured and build in close consultation with the users. This consultation will take place with the researcher among others, to determine the correct configuration. It ensures they comply with the specific demands and requierements of the plant growth tests. A detailled instruction guide is included.

Cooling 

The plant growth rooms are often executed with a ceiling cooler in combination with an airsock. The dimensioning of the ceiling coolers is closely related to the used lighting. Various types of cooling installations are used. The choice depends on the desired RH in the space. 

 

The refrigeration can also be connected to the present cooling installation and to a cooled water supply pipe.

 

Air regeneration 

The air injection method is based on air suppression. The air flow rate depends on the released warmth of the lighting and is determined per situation. The air flow rate will have to be adjusted again to maintain the correct temperature.

Lighting 

There are various kinds of lighting possible. Setups with LED fixtures with day-light color, or dimmable fixtures with the red, far-red and blue light colors are possible.

 

 

 

Humidification 

Different kinds of air humidifiers are possible. The most used method is an ultrasonice humidifier in combination with a reverse osmosus water treatment unit.

 

 

ABC processor

Use the advanced ABC processor to configure and reach every desired air condition, light intensity and color spectrum on a touch screen. This can be done in various time stages and with or without gradual scale transition; day and night rhythm with dusk and morning glory is an option. The composed menu can be saved as pre-set and used for the next test; 32 pre-sets in total.

Below you will find an example of the menu:

Stage 1 2 3 4 5
Duration (min.) 65 50 130 140 600
Intensity (lux)* xxxx yyyy zzzz aaaa bbbb
Red (%) 30 40 50 60 30
White (%) 10 10 20 20 30
Blue (%) 40 30 10 10 30
Far-red (%) 20 20 20 10 10
T° (°C) 25 25 30 35 15
RH (%) 60 80 60 45 40
AH (gr/kg) 12.0 16.0 16.0 16.0 4.3

 The entire proces is controlled with the ABC processor which is provided with a touchscreen. One ABC processor/touchscreen can operate several plant growth rooms. All settings and measurement values can be saved to your pc using the ABC PC Program. These values can be called up again in a graphic or table for analysis. This makes it possible to, if needed or desired, have a tailored adjustment of the processes (Pre-sets).

Furthermore there is an SMS Module to send an sms in case of emergencies, and a MCM Module for operation and monitoring (including graphics) from your smartphone or tablet.

The ABC guard thermostats will intervene when the temperature in the room becomes too high or too high. All equipment will be shut down to prevent damage, followed by an alarm. After the alarm, an sms message with detailed information can be send to the responsible persons.
