Cannabis Light Response Curve

[LargePrime]

Does anyone have information or a link on cannabis specific photo response curve? Or the closest thing to it?

It seems there is a significant difference between C3 and C4 plants specifically, and I wondered if work had been done to find our specific plants curve, or what it is close to?

I put this in Growroom lighting because it seems to me that we really can't compare light sources without knowing this. If you think it might do better in another forum, please advise.

For example This picture

Shows a Heavy weight of Blue

But this

shows far more red.

If you follow one curve you are going to want way more blue and UV in your light source. If you follow the other, you are going to want way more red.

Please advise.

I would imagine the exact curve varries from cultivar to cultivar. For what its worth I personally have seen happier plants when adding at least some MH to your bloom room. There are also scholarly articles suggesting ultraviolate helps cannabinoid production.
