We discussed this elsewhere and the consensus back on Breedbay (bodhi’s old haunts) was that Suge PK was a bubba s1 or very close relative of bubba kush, and that Hollywood = LA Pure Kush, but Topanga is a different cut. @Strayfox actually confirmed here that Hollywood = LAPK, and that Topanga is an entirely different cut altogether.
Still, though, based off the pics I saw on Breedbay of the cuts bodhi’s working with and lots of their crosses flowered out, the bubba is a short spear producer, and a very slow grower, whereas the LAPK is a more vigorous and stretchier spear producer, without necessarily being viney like an OG.
Keep in mind that these are contrived stoner categories; they’re not real biology phylogenetic or taxonomical classifications. Like everything else in cannaland, they’re inconsistent and full of contradictions, at the best of times.
