UV-B irradiation differentially regulates terpene synthases and the terpene content of plants, cannabis in particular. Results can vary drastically but have been shown to alter profiles in surprising ways, Gran daddy purple is known for its strong lavender smell, this is attributed to the terpene linalool which given a correct schedule can x3-4 the already high levels.
When we look at terpene production, we not only look at the "sugars" it needs to build complex proteins but also the efficiency of the mechanisms that produce the terpenes, can this be sped up using enzymes? Yes
are there ways to manipulate over-production using environmental triggers? Yes.
Moreover, temperature, relative air humidity, and CO2 concentrations are other abiotic factors influencing cannabinoid biosynthesis. Significant variations in the cannabis plant morphology and secondary metabolism have also been reported in response to light intensity and quality.
Identical gentical clones grown indoors and outdoors always have different profiles and always have less terpene when grown indoor.
