Then what happens to the A and C? We know red (far) light is bounced off, and green is reflected too. So this means all other light would be absorbed into the trich' at the same time... likewise magnified.

Could the chemicals, like MM said, be created to divert the different spectrums? Hence the varying cannabinoids in the first place?

Also the chemical responsible for smell, he makes no mention of that... Ed Rosenthal, put the chemical as THCV... the plants with high levels of this chemical are usually the most potent strains. Could it in fact be the THCV that is created by by one of the UV ranges? THC created by another, and CBD created by the other one?

Hence the reason for the two sets of cells in the trich'.

Also, why would cbd be derived from THC? Maybe THC is derived from THCV, and CBD is derived from CBN. The reason for the two sets of cells, could be to process light from both extremes of the spectrum. The cell responsible for smell (i forget the names now, and scrolling down doesn't reveal enough, sorry) reacts to blue, and the part responsible for cbn reacts to red?

Hope that makes sense.
