From what I remember, the lighter color specis of the AG plant was just a natural defense byproduct of the plant caused by eons of natural selection caused by the intense sunlight of that region. Darker plants just quickly burned up so the lighter ones were the ones that propigated.
They were just lighter colored plants and drying made it look more Golden than green. I do remember the seeds being light colored and real small also.
Panama Red was more tropical and same/same, had a red hue after dried. It on the other hand had big fattie seeds.
Supply & Demand created the market for bleached or treated weed so many methods have been tried to rip people off by calling their bleached junk, AG.
But in fact, the real deal was just a lighter colored strain, I believe. And DAMM. I wish I had saved some of those beans! S
