Thank you for the extremely informative reply! It sounds like legalizing cannabis and making it a major industry might not have been a good thing in terms of a reduction in biodiversity and killing the incentive to preserve granddaddy strains. One would like to think a balance could be found, but I am not sure if that is a practical goal at this point.

I suppose it would be possible to get old school seeds from elsewhere in the world where weed still either grows wild or isn't grown with the same commercial goals, maybe.

Thank you again for taking time to explain something of the science to me :-). It's actually very interesting. my only experience with deliberate selective breeding involved heirloom tomato plants and carnations.
