I'm asking because Matt Berger got his "bubba" line from a frat friend in that region.The bagseed that my cut came from was doing the outdoor rounds in S Florida for a couple years so maybe early to mid 90's was when they hit the beach I suspect.
So without getting too deeply involved I would think the better question is why are the so many "Bubba cuts" when there should only be one.
I did not name my cut Bubba that was done in cali as a marketing move I call it D1.
He had a seed plant going of this "bubba" which he suspected was some sort of NL but it's pure speculation. That was the plant that was pollinated by a herm OG and bubba KUSH came out of that pollination.
