hi
first I have to mention that i didn't manage to read all the news on 'perfect grow' so forgive me if I ask/say smth that's not new..

knna, could you please gimmie a hint where should I buy small numbers of LEDs in EU? do you live here actually, I noticed you removed Spanish flag from the profile?

btw, I wouldn't say cannabis is little demanding about light quality (otherwise we could grow under MV ie.), better to say it's just resistant as a weed and grows quite good under different conditions. just a better word.
wheat is a monocot so not a best comparison. still good, as most important photoreceptors are so old origined that are found ubiquitus, and crys are found in likely all animals, including mammals, as humans, for sure
I'd rather say cannabis will benefit from more complex spectrums. but in this topic I mostly wanted to ask for a hint at the moment, dont really know if I want to talk about quality here. thanx a lot in advance

another question.. do you think(have you experimented) that in vivo it doesn't make a critical difference to have equal quantity of photons at, say, 10 or 20 nm away from 660 and other peaks? as we know from mcree and inada it doesn't affect photosynthesis rates much, but what about the overall effect?photomorphogenesis, plant architecture?

third..what's more efficient for FR, blacklight incands or blacklight fluos?
