there seems to be some conflicting info on just how stable TGA thinks Vortex is. On the one hand you have this from the TGA site.
This is our most stable hybrid and most well received strain. When someone asks which of our strains should I try? I always recommend Vortex.
And in other descriptions for seedbanks:
This strain is offered mainly to collectors who have experienced the high or unique smell of either parent. This is not a strain for someone new to indoor growing or large scale grows looking for big production. It is a strain that with luck you can find a once in a lifetime mom for head stash.
Phenotypes: Large variation with phenotypes like both parent strains
Expect weird mutations and incredibly sticky freaks of nature. This hybrid tends to grow like a vine and need serious tending to achieve decent yields.
This Vortex Phenotype is not a huge yielder, and will not win any beauty contests that's for sure but for someone who has a connoisseur palette the genetic makeup of Vortex makes for some mighty stony, awfully tasty herb
