Nirvana Seeds vs. Originals?

[herbie the love bud]

F= filial generation of a hybrid.
F1 is the first hybrid generation
F2 and beyond are interbreedings of the previous filial generation.

So in the scheme of things, would a Dutch Passion WW be an F and a Nirvana WW be an Fx? And what would that mean about the plant?

BTW Stinky, I love that title "CultiModerVatorAtor." When I read it high I keep hearing the nice voice, "what vibrator? Who ate her?"

Thanks
