Abstract

Recently, medical cannabis products are being legalized worldwide.
THC and CBD are the major cannabinoids for therapeutic purpose especially in the nervous and immune system.
Cannabinoids yield depend on many factor, one of important factor is light because light quality under indoor planting influences growth and secondary metabolites in photosynthesis.
In this study, we conducted experiments on the growth of Cannabis and on cannabinoid content, including by THC and CBD on the conventional drug type (high THC ratio) from Khon Kaen University (‘KKU01’ and the ‘KKU’ F₁ hybrid). All plant were grown by using difference LED light spectrums consisting of white LED, red:blue (1:1) and red:white (1:1). Twelve weeks after transplantation, the plants under white LED conditions, showed the shortest plant height.
Meanwhile, red:blue (1:1) LED stimulates the Cannabis to produce chlorophyll A and chlorophyll B more than the other LED types.
And the conditions red:white (1:1) LED gave the lowest Cannabis inflorescence yield.
We found that the ‘KKU01’ and ‘KKU’ F₁ hybrid did not produce CBD, but only THC was present.
All of the LED light spectrums showed non-significant on the percentage of cannabinoid.
Moreover, in terms of difference types, we found the ‘KKU’ F₁ hybrid had properties to give high percentage of cannabinoids more than ‘KKU01’.
