They're not.
OG 18 was found in 40 S1 seeds that came from Breeder Steve...
One would have to assume that since Breeder Steve worked with SFV in a couple of his crosses, that they would likely have been SFV S1s.
Karma Genetics OG 17 was a more sour (terp profile) from the same seed lot - I think that he used that #17 in the Bear OG seed line...fwiw.

Why are you always trying to compare your rp sour diesel cross to different clones with some half brained theory on the genetics ?The way that dna speaks about it tho, I would have guessed ghost or sfv.
But my og hookup just told me he remembers them being from a different og, as per Karma, but deffo said 17 and 18 were from the same batch from breeder steve.
I will try to get a link ...
