F2

I suppose if I keep on growing, and I will, I should learn this stuff. I think I know this though. An F2 is a second generation from a plant that had F1 parents. Is that right? So Joey Weed's F2 White Widow would be the grandchildren from the original mother?

F2 is the next generation after a first generation (F1) hybrid.
ww x nl = F1 hybrid.
(ww x nl) x (ww x nl) = F2 hybrid.

That's about what I thought. Thanks.
