Set-up of trials
The trials compared results of medical cannabis crops grown under HPS and LED lighting in a greenhouse. First, a crop was grown under HPS lighting. After this crop was harvested, another crop was grown under LED lighting under the same conditions and in the same trial area. This set-up was repeated several times under HPS and the LED set-up was run a total of 3 times in that same compartment. Afterwards, the two cycles and crops were compared.

In our long-term research collaboration with Wageningen University & Research (WUR), we are investigating how LED grow lights can influence compound production, quality and plant characteristics of cannabis crops grown for medical purposes. The research results will support growers in creating the ideal growing conditions for medical cannabis.

*These results are based on the specific characteristics of these trials. We can estimate yields of 50-100 grams per plant, depending on the variety, planted at a density of 9-10 plants per square meter. The LED light intensity used was a medium intensity of 800 µmols/m2/s.
