Great! Many thanks for this reply.
What Is not clear to me (from my very narrow point of view):
How did Oregon CBD created millions of stable seeds by crossing Ruderalis and Original White (high THC). They needed to select those parents so the final seeds are always similar?
Lets say I manage to select a stable mother from these seeded CBG bud testing 0.1% THC. The S1 seeds created from this one by STS method wont all carry the same genes and some can still possibly test hot?
