@DonPetro what are your thoughts, brotha?

NWs should be used from start (either clone or seed ) at high power,
gradually decreasing to null ,after the first two weeks of 12/12 ...

WW 3000K is the basis ,and should be on ,from start to harvest ...
Increase - @ mid flowering ,peak in power- decrease

Deep reds ,should be gradually increase in power from the start ,
to peak during mid flowering and then gradually decrease afterwards ...
(could be in same channel as WW ? )

Far reds take over ,as their power should be increasing from mid flower ,peaking about harvest time ....

That is probably the closest "long term light quality alteration scheme " ,maching mj seasonal spectral
absorptance under natural sunlight ,using 4-5 different types of LEDs ...
( 3000K - 5000K -675 nm -720 nm -800 nm)

Not sure how i feel about the whole spectrum thing. I feel its still very much up for debate.
Here is the spectral chart for the Vero 18 cob:

Compared to the Eye Blue metal halide which many swear by for flowering:

I feel that using lots of blue supplemented with reds may be the way to go.
Consider if you will this graph in relation to the two above:

Its quite an interesting subject. Look forward to hearing from you on this. Maybe some others can chime in as well.
