Guy from ledideal.cz has told that there is no reason to use uv and ir in leds, no effect after we all read much info how its important. Only reds 660 doing the work, ) i know its not direct answer but when they tell you need extra uv and so on maybe its a shit. But personally I will try cmh with leds for thíse type of sativas
CMH gives some UV... but I was asking about leds and their light spectrum. if it is true that sunlight in tropics is more blue, 450 - 490 nm, then 660 nm doesnt seem so ideal. but I am no expert..
