Solacure "flower power" UVB is theee only UV light to operate at 280nm, 280 is the cutoff point between UVB and uvc, no other company has patents on the glass, do yourself a favor spend the money if you can no only can you achieve THC increase of up to 30%, it eradicates mildew, disintegrates small bugs and insects to boot.
90% of all THCphotosynthesis that happens in the UV spectrum happens
@280nanometres. Be very careful though as it's almost impossible to see with other regular lights, doesn't take long from exposure to feel the burn on the skin.
the moral of the story, pre-emptive prevention is the best solution. Good luck and I wish you very happy growing.
