A new study conducted by the Wageningen University & Research Centre in The Netherlands indicates that medicinal cannabis can be grown well in greenhouses under LED lighting. In fact, according to the study, some varieties of cannabis plants grown under LED lighting may even produce more medicinally active substances than if they had been grown under other intensive lighting systems.
The study also revealed that medicinal cannabis can be grown well under high lighting levels. The study was commissioned by Lemnis Oreon, a developer and producer of LED lighting concepts, and PB Techniek, a supplier that caters to the international horticulture sector.
Experts in greenhouse technology at the Wageningen University & Research Centre conducted the study in the spring of 2016 to analyze the influence of cultivation conditions on the growth and yield of medicinal cannabis. The study measured, among other aspects, the quantities of Cannabidiol (CBD) and Tetrahydrocannabinol (THC) produced. CBD is used in the Netherlands to treat such diseases as Multiple Sclerosis. THC is used to combat and alleviate medical conditions such as Tourette’s syndrome or therapy-resistant glaucoma, and such complaints as weight loss, nausea, and vomiting.
Because not enough information is currently available about the cultivation of medicinal cannabis in greenhouses, the researchers at Wageningen also investigated other factors that influence cultivation, such as temperature, moisture, and plant nutrients, as well as the incidence of pests and diseases.
