Okay boys so when you emit UV light onto your plants foliage, These UV photons "Stimulate" UVR8 Receptors.
When you stimulate UVR8 receptors you can get more potent THC, better Terpene profiles, and you can even make the plant produce more cannabinoids.
But not all UV light is created equal, UVB photons are hundreds of times more energetic than UVA, because of this UVA photons cannot make the plant produce more cannabinoids only UVB photons can do this and THC/CBD are cannabinoids so if you want more THC/CBD? than get UVB!
But shorter wavelength UVA photons do stimulate UVR8 receptor's so UVA light can give you better terpene profiles and it can also make your THC more potent because UV light is critical to the development of THC.
But beware UVB photons are so energetic that with prolonged exposure UVB light can actually cause damage to plant DNA.
and UVA light can actually help reverse the damage done to plant DNA by UVB light, this process is called photo repair were UVA light induces the expression of photolyases which are enzymes that repair UV-induced DNA damage.
I hope this Article Helps Someone
Peace Happy Growing.
