Can you grow marijuana with black lights during the dark period?


#1

I know a marijuana grower who supplemented her fluorescent lights with black lights during the dark period, and many people thought it was great. What’s your opinion?

Research on UV-B light has shown that it increases THC content in a linear ratio. I am not aware of any controlled research on the effect of UV-A, which is the light that comes from black lights, but some marijuana growers have suggested that black lights help increase their plants’ potency
