I’ve been down that rabbit hole
So there’s no official lineage… old heads seem to agree* it could be
Cali Orange = Thai x [Afghani x Acapulco Gold]”
Or
“thai x early girl [Afghani x Mexican Sativa]”
The 2 persons to know for sure would be Sam skuntman and the guy that bred it.
All Sam could answer when questioned about calio lineage is “I know who bred it and what’s in it” without any info…
Someone else hypothesized early girl x thai, the thai being the mother of some other legend from that era. (Bshw?) Tying many lines to very few starting material
