Damn, those plants from the OP look identicle to bubba don't they, Thats crazy.
There gotta be some Bubba in the sourbubble, he's BX sourbubble 4 times now, what is he BX it too?? BX 4 times would bottleneck a strain wouldn't it? So that a certain pheno would be more avalable than others?
Looks like every BX looks more and more like the pre98 Bubba. I would guess the mother clone he breeds back to is at least 50% Bubba and not pure White Label Bubblegum as Bog claims, the pictures don't lie, but why hide the truth for so long?
