LED research in greenhouse cucumbers in the 2022/2023 season

In the 2022/2023 season, the team with Plantalux tested their new LED luminaires with different spectral compositions and their impact on the cultivation of greenhouse cucumbers. 

As every year, the tests were carried out in research facilities belonging to the Warsaw University of Life Sciences in Warsaw, Poland.

Lighting was installed in three autonomous chambers: wide spectrum LED, narrow spectrum LED, and HPS as control.

The above short video presents tests carried out on the cultivation of greenhouse cucumbers. From left, cultivation under HPS, broad-spectrum LED, and narrow-spectrum LED.

In each case, the lighting intensity was the same so that the results were as reliable as possible and reflected cultivation in commercial conditions. The table below contains aggregate data from November 30, 2022, to February 26, 2023.

In each case, the difference is calculated in relation to cucumber cultivation under HPS lamps (control). The best results were obtained under LED lighting with a wide spectrum of emitted light.
