take a look at my spectrum chart.. u have to consider these focal points, where the Photosynthetic curve meets with the rate of chlorophyl absorbtion, as opposed to the LED. 635nm is in the orange-red range of the spectrum.. The photosynthetic response curve is at its peak. This would be optimal for flowering because thats the stage where its photosynthetic response is at its highest.. the 470nm in the blue spectrum is optimal for the vegetative state, where its chloropyl absorption rate is at its peak, which is used to produce energy.. it'll need energy for flowering...
sheist Reviewed by sheist on . LED grow lights... input please. Hello guys, I'm exchanging eMails with a representative from a LED company. I asked him if they could produce a custom light for growing, and here's what he told me: Our options are as follow: 940nm, 850nm, 660nm, 630nm, 610nm, 590nm 570nm, 530nm, 510nm, 470nm, 460nm, 400nm and a total of 64 LEDs in the bulb.
