Revolutionizing green tea cultivation with growth chambers and Clitec technology.

Green tea, a globally appreciated beverage, has a long history of traditional cultivation in the shade in Japan. However, with advances in technology and scientific research, the cultivation of green tea has evolved significantly. One of the most promising developments is the use of growth chambers, supported by state-of-the-art technology such as Clitec. In this blog, we’ll take a closer look at the potential benefits of growing green tea in growth chambers, the role of LED technology in controlled environments, and how Clitec can revolutionize the green tea industry.

LED technology and controlled environments

The development of light-emitting diode (LED) technology has revolutionized various fields, and agriculture is no exception. In agronomy and plant physiology, researchers use narrow-band emitting LEDs to study the influence of lighting conditions on plant growth. The precision of this technology allows fine tuning of the spectrum and amount of light irradiation, making it ideal for growth chambers in controlled environments. Plant factories use this technology to achieve optimal growing conditions and unique benefits such as pesticide-free production, stable yields and enhancement of certain components in plants.

Improving the properties of medicinal plants

The use of LED technology also extends to the cultivation of medicinal plants, where lighting conditions are optimized to maximize beneficial component variations. Studies have shown that adjusting the quality of light can increase the healing properties of plants such as St. John’s wort and Glycyrrhiza uralensis. This knowledge opens up exciting possibilities for growing high quality medicinal plants with enhanced bioactive compounds, all within the controlled environment of growth chambers.

Sensory properties of plants and multi-marker profiling.

Although research on the relationship between light conditions and the sensory properties of plants is still limited, it plays a crucial role in the production of high-quality products in plant factories. Traditional evaluation indices such as amino acids and L-theanine were used to evaluate the quality of green tea. However, a more comprehensive approach is required for high-quality teas. Multi-marker profiling, a powerful method that uses metabolomics to evaluate multicomponent traits, has been proven in several food quality assessment studies.

The experiment on the cultivation of green tea

In a fascinating study, researchers intended to uncover the relationship between sensory properties and light conditions in green tea (Camellia sinensis L.) plants using growth chambers and multi-marker profiling. They conducted the experiment in three stages:

Stage 1: Identification of high quality teas

The researchers analyzed high-quality green teas (tencha) from a tea competition and focused on amino acid content. The objective was to evaluate the specific amino acid composition contributing to high quality teas, with precise control of light conditions in the growth chamber.

Stage 2: Development of artificial cultivation techniques

Using the leading cultivar Yabukita, the researchers developed artificial cultivation techniques for tea plants under simulated conditions of open tea cultivation. Growth chambers played a critical role in this phase, allowing researchers to carefully control light conditions to mimic open field conditions and produce high quality tea.

Stage 3: Evaluation of artificially cultivated (AC) teas.

The researchers analyzed the AC teas and compared them to the highly rated teas to understand the relationship between the light conditions controlled in the growth chamber and the quality of the tea.

The contribution of Clitec

Clitec’s advanced growth chamber technologies, including LED lighting systems, climate control and real-time data monitoring, enable researchers and growers to optimize the growth environment with unmatched precision. The growth chambers offered by Clitec allow for a controlled environment and ensure consistent and optimal light conditions throughout the tea plant growth cycle. As a result, growing green tea in growth chambers equipped with Clitec technology achieves high-quality teas that rival the winners of traditional tea competitions and set new standards in the green tea industry.


The combination of LED technology and growth chambers revolutionizes the cultivation of green tea. Through multi-marker profiling and precise environmental control, researchers can unlock the secret to growing high-quality teas that meet the highest standards for flavor, aroma and fragrance. With the help of the most modern growth chamber technology.
