A friend of mine grew legally CBD plants but the problem is the outrageously low THC limit of 0,2%. After he completed the harvest he sent samples of the buds for lab analysis and results came back showing 0,6% THC and 13% CBD. Now he cannot legally sell those flowers.
He read about UV lights being used to lower THC concentrations...? Does any of you guys know more about the subject? Anyone who has tried it perhaps? Thank you very much for any answers.
Adding UVB during the last 2 weeks of flowering can add up to 27% more THC to the plant. But it's given in small doses, depending on how high the light source is from the plants. It could be as low at 10 minutes 3X a day. There's some links in my Orange Gasm thread that discuss college studies on the subject.
But the issue is it's a really bad light on the human body, mainly the eyes and skin........ plants don't really like it either, and produce more resin as a defense mechanism to defuse the UVB before it hits the leaves.
in the EU we now have a limit of 0.3% Total THC,
yeah such a machine exists and is used widely as most cbd growers have this problem!
no idea what kind of tech it uses though, only know its about 20K to get one
