None of them. Fem seeds are whack. A backwards step in breeding, devoid of any real work. Why do you think real breeders like DJ, Steve, Shanti, Neville, Chimera, and Karma absolutely refuse to produce them?
The big Dutch seedbanks hyped fems as the next great thing, but they're really just the path of least resistance. It's a lot easier to reverse a momma than actually work with studs to line breed consistent stock. IMO, reversed pollen chucks don't constitute breeding.
Now that the the mainstream has accepted the idea of fems at face value, they demand them, and the seedbanks have to supply them to stay competitive, even though they know the many disadvantages.
I think they're just for people too lazy to make a selection from a standard pack. Their instability means they absolutely aren't worthy of further breeding projects, and pose a threat to the maintenance of special genetics. In other words, fems are the road to mediocrity.
The worst thing of all about fem seed is that seedbanks somehow think it's justifiable to sell them for more money. WTF?!? How do they justify the price discrepancy when everything about fems makes seed production easier and more efficient?!? The answer: hype and a consumer base lacking a solid understanding of what they're actually buying.
Stick with naturally produced seed lines. If you do run fems, use them as a one and done fix, and for god's sake, please don't pollute the gene pool by crossing them with anything else.
