Don't really get you on this one

there are no 'cannabinoid free' cannabis plants in existence of which I am aware.

Even the ditch weed hemp on the powerline at my grandad's farm produce cannabinoids, but not much thc I can tell you that for certain. Beyond that you assert that volume is the difference but the actual difference is the presence of thc synthase in one plants trichs and not the others. A high trichome density and large glands would indicate a more cannabinoid rich strain of course but simply stating that the trichs are not filled is incorrect imo. Here is a link to some good info on the structure and function of trichs from that lucky hoosier Mahlberg.

TERPENE interesting theory but again I would hesitate making generalizations about this genus it always has some cultivar that is an outlier, like the grapfriut haze, or the purple wreck which we grow both send you to orbit and give you tics if you smoke too much and are every bit as covered in glands as that beautiful picture you posted.
