Climatron plant growth cabinets are widely used in plant biology research, horticulture, and agriculture. They allow for precise control over the growing environment, which can significantly influence plant growth, development, and productivity.


Our Climatron reach-in plant growth cabinets are designed to maintain conditions that are critical for a wide range of research applications where temperature, humidity and lighting need to be precisely controlled, including:

  • Arabidopsis
  • Seedling storage
  • Seedling germination
  • Plant growth
  • Plant pathology
  • Plant production
  • Tissue culture
  • Propagation

Three sizes of Climatron Growth Cabinets are available, single-door upright 360L and 520L capacities, and a double-door 1100L capacity. An upward, fan-forced airflow maintains the cabinet’s conditions – so your plants will thrive in superior temperature uniformity.

A 50mm cable/monitoring porthole is located in the side wall so that you can slide through your remote measurement devices. Humidity and carbon dioxide control are both optional in all sizes, so customisation is possible to suit your application and budget. 

With a Colorbond exterior, stainless steel interior and PVC-coated shelves – these cabinets are highly corrosion-resistant and easy to clean. All cabinets are fitted with heavy-duty lockable castors to allow cabinets to be moved easily when the cabinet requires servicing or the area around the cabinet needs cleaning. 

Need to adjust the temperature, lighting, humidity or carbon dioxide in the cabinet? With our Select Touch and Run (STAR X) touchpad control system, you can do it with ease. Thanks to our STAR X touchscreen control system, you can easily adjust and program the temperature and humidity settings in the cabinet. The STAR X allows for the operator to synchronise programmed settings to real time and has an ethernet connectivity which, once connected, will allow the operator to perform all functions via a PC. The STAR X logs the performance of the cabinet to onboard memory. This memory can hold up to 365 days of logged data and for ease of use,  we have incorporated a live trend screen to allow the operator to quickly check the performance conditions within the cabinet. Alternatively, the operator can download the logged data to a USB flash drive for archiving or review via a PC. No specific software is required to view logged data. A simple spreadsheet program is sufficient (Microsoft Excel or similar).

Data can be viewed in real time, logged for up to 800 days and downloaded onto an Excel spreadsheet – so you can be sure of your lab’s consistency and efficiency.

Based on almost 100 years of experience with lighting technologies, Vossloh-Schwabe develops and manufactures LED solutions on proven industry platforms that can be individually tailored to suit your specific area of application. The Climatron utilises high-output LED lighting in three colour options: 4000K, Leaf (2700K) and Bloom (1900K). 

4000k: Because the light is neutral, not leaning in favour of red or blue spectrum, it can be described as ‘standard’ and is the closest equivalent to Cool White T5 fluorescent lamps.

Leaf (2700K): 'Leaf' is the recommendation for plants and vegetables which should have an optimized vegetative growth. Due to increased spectral emission in the far red (> 700 nm), as well as in the green (500–560 nm) spectral range, the growth of the plants or the vegetables can be positively influenced.

Bloom (1900K): 'Bloom' shows an optimized effect on ornamental plants and young seedlings, which need support in the flowering or in the initial growth stage. The spectrum is characterized by its focus on the blue and red spectral range, which provides maximum efficiency in photosynthesis.

What are the advantages of using an ultrasonic humidifier to generate humidity?

There are several advantages to using an ultrasonic humidifier to generate humidity:

  1. Energy efficiency: Ultrasonic humidifiers use less energy than other types of humidifiers, such as steam humidifiers. This is because they use high-frequency vibrations to create the mist, rather than heating the water to create steam.

  2. Less heat: As above, no additional heat into the chamber allows for less energy consumption from the refrigeration system and the ability to control lower temperatures.

  3. Low maintenance: Ultrasonic humidifiers have fewer parts and are less likely to become clogged or dirty than other types of humidifiers, making them easier to clean and maintain.

What is a plant growth cabinet?

A plant growth cabinet, also known as a plant growth chamber, is a controlled environment system that simulates and studies plant growth under controlled environmental conditions. It typically has an enclosed chamber with controlled lighting, temperature, humidity, and carbon dioxide (CO2) levels.

Plant growth cabinets are used in plant science research to study the effects of environmental factors on plant growth and development. By controlling environmental conditions, researchers can investigate how plants respond to temperature, light intensity, humidity, and atmospheric composition changes, among other factors.

Plant growth cabinets can study various plant species, including crops, horticultural plants, and model organisms such as Arabidopsis thaliana. They are also used for plant breeding, genetic research, and testing the effectiveness of plant growth regulators and other agrochemicals.

Plant growth cabinets can vary in size and complexity, from small bench-top models to larger walk-in chambers. They are typically equipped with sensors and controllers that allow researchers to monitor and adjust environmental conditions to maintain precise control over the growing environment.

Why is it important to have efficient light in a growth chamber?

Efficient light is essential in a growth chamber because it directly affects the growth and development of plants. Light is a critical factor in photosynthesis, the process by which plants convert light energy into chemical energy to fuel growth and metabolism.

Efficient light in a growth chamber refers to using high-quality, energy-efficient light sources that provide the appropriate light spectrum and intensity for optimal plant growth. The light spectrum and intensity requirements vary depending on the specific plant species and growth stage. For example, plants typically require higher levels of blue light during vegetative growth and higher levels of red light during flowering and fruiting.

Efficient light in a growth chamber also refers to using light fixtures and reflectors that minimise heat generation and distribute light evenly across the plant canopy. Excessive heat can damage plants and reduce their growth, so it's important to use light fixtures that generate minimal heat and distribute light evenly to prevent hot spots.

Efficient light is essential in a growth chamber because it can significantly affect plant growth and development. A sufficient or low-quality light can lead to stunted growth, reduced photosynthesis, and lower yields. In contrast, efficient light can promote healthy growth and development, increase yields, and enhance the nutritional value of crops.

What is the best colour light for plant growth?

The best colour of light for plant growth depends on the specific growth stage and the type of plant being grown. Different light colours can promote different aspects of plant growth and development, and plants have different optimal light requirements depending on their species and growth stage.

In general, plants use red and blue light most efficiently for photosynthesis. Blue light is important for vegetative growth, as it promotes the development of chloroplasts, which are responsible for photosynthesis. Red light is important for flowering and fruiting, as it encourages the production of phytochrome, a pigment that regulates the timing of these processes.

However, green light is less efficiently used for photosynthesis by plants because it is reflected by chlorophyll, which makes plants appear green. Green light may even inhibit some aspects of plant growth. As a result, some researchers have suggested that light sources with a higher proportion of red and blue light are more effective for promoting plant growth.

In addition to red and blue light, plants also require small amounts of other colours of light, such as far-red light, which can promote seed germination and regulate plant development.

What is Dew Point?

The dew point is the temperature at which dew (condensation) forms and is a measure of atmospheric moisture. It is the temperature to which air must be cooled at constant pressure and water content to reach saturation. Dew points are expressed as a temperature. Higher dew points correlate to higher moisture content, also known as absolute humidity.

The dew point represents the lowest temperature to which air with specific temperature and relative humidity (RH) can be cooled. At the dew point, air has a relative humidity of 100%, and additional cooling produces condensation rather than lowering the air temperature.

Do I need a water tank to supply water to the cabinet?
You only need a 25L/55L water tank if your cabinet cannot be connected to mains water supply. If mains water supply is not possible, 25L gravity and 55L pump water feed tanks are available to supply water to the cabinet. As a rule of thumb, a cabinet running at 90%RH will deplete a 55L water tank in approximately three days.
