Now chlorophyll has an absorption spectrum,

and you can isolate that molecule and look at it, and it actually absorbs primarily in the red and the blue, not in the green.

Chlorophyll A and B are slightly different, but if you take those together, it gives you a peak of absorption that's in the red, and then a second peak that's in the blue.

Okay, so first right there, you might just assume that plants only want red and blue light, and that's somewhat true.

Actually, when the first horticulture lighting came out, they were just combining red LEDs and blue LEDs.

It had this magenta color.

You may have seen that before if you've ever been to a grow operation.

Where have you seen this actually move the needle? Like what actually has happened when it is implemented?
