We been studying UV and cannabinoids for years, what's changed today.Solacure started out in 1980s making tanning lights for Show Pigs, and for ageing wood. If you dont know it, buying new guitars, that appear old, are a fad nowdays, and has been since the 90s. The use powerful UVA/B lights to age the wood, and paint. The guitars are called Relics. Fender makes them, and others. Solacure started out with other types of lights long before the started making UVA/B.
They arent the only to study UVA/B.
Phillips has been making UVA/B for decades, and much of it for the medical field to treat Psoriosis, and other skin diseases.
Hortilux also has alot of UVA/B studies.
NASA studied weed in 72-73 on Skylab, and proved they could change the chemical profile by using massive, millisecond flashes of Xenon. I burned the plants, and made them produce more oil to protect it.... Weed was one of, if not the first plant studied in space, on Skylab.

UV Light for Boosting THC in Cannabis | Vanessa Nielsen
Growers looking to increase the quality and potency of their cannabis plants may consider adding UV light to their grow setup. But does it work?vanessa-nielsen.com
Debates can go back and forth forever about what the exact biological role of cannabinoids in the marijuana plant really are, perhaps a more likely explanation is that cannabinoids are a natural defense mechanism to a variety of assailants from the outside world: pests, mold, disease and ultraviolet radiation. Evidence shows that ultraviolet light can increase potency and resin production, though the whole picture of what cannabinoids do for the plant still isn’t clear.
Ultraviolet radiation in all forms can be damaging, but UVB rays specifically damage proteins and nucleic acids in the cells harming processes of cell reproduction and metabolism. The energetic, short wavelengths rays of UVB radiation pack the punch, and are largely responsible for sunburn and play a major role in skin cancer.
To defend against UVB, some plants produce flavonoids that can absorb the radiation. In humans, exposure stimulates the production of melanin to defend against the sun.
Evidence shows that cannabinoids, specifically THC, may play an active role in defending the cannabis plant against UVB rays, and strains native to areas with high levels of ambient UVB radiation show higher levels of Δ 9THC.
How did they figure this out? Finding out where the best pot in the world grows naturally was the first step. Typically, the best cannabis for hash grows in elevated regions. According to a book about hash (Bergel, 1965):
“When we were still working in this field we were told that the production of the active resin, in any kind of Cannabis plant, depends entirely on the altitude of the plantation; for example, you get rich charas or bhang in northern India only at a certain height above sea level. It was also reported that in order to obtain active resin one had to plant Cannabis in Germany near Roserheim, not far from Munich, which again is above a certain altitude.”
The less atmosphere you put between you and the sun, the more light you receive, and for cannabis plants this means making more resin to defend against UVB.
Plants grown above the 30th Parallel North typically have higher levels of CBD relative to THC, and plants originating from between the 30th parallel north and the 30th parallel south have higher levels of THC with little to no CBD. The first encounter with a South African strain that had high levels of THC with not a trace of CBD in 1973 reinforced this theory given the high natural UVB light intensity in the area.
High THC is found naturally in strains between the two parallels shown in the map. Areas of high hashish production in the Rif Mountains of Morocco, the Beqaa Valley of Lebanon and the Hindu Kush are all on the cusp of the 30 °N, but are all at a high altitude. This perfect balance of climate and sun exposure allows those places to grow the greatest hash plants in the world.
Presence of cannabinoid-rich trichomes near and on the seedpods, added to the fact that male plants barely produce trichomes, it seems logical that these resinous glands function, at least partly, to protect future offspring from the sun.
A more recent side-by-side comparison of plants grown with and without ultraviolet radiation backs up these older theories. So-called “drug-type” plants (strains cultivated for their naturally high levels of THC) produced higher levels of THC, but not other cannabinoids, when exposed to UVB treatments regularly.
Trichomes deal with an abundance of stress, UV isn't anything special, the claims on 15-30% seem fabricated not real.
Also I know some scientists in China who have been studying this in many species, this would be a breakthrough in their research and serve as another basic model in gene regulation.
