Simple (?) Breeding Question

So I'm currently growing out a few seeds that I got thanks to a hermie'd plant in a previous grow. Here's the genetics.

Father -

Blueberry (Dutch Passion, NOT DJ Short's) - Originally a feminized seed that hermie'd on me, in fact a had a few of these seeds and the only viable one hermie'd...I was really not happy with the product.

Mother(s) -

Lemon Skunk (DNA Genetics) - AWESOME strain, loved growing it
Jack Herer (Sensi) - Another big winner

My question:

So I'm growing two crosses: Blueberry x Lemon Skunk and Blueberry x Jack Herer.

Am I growing out an F1 generation, or were the parents an F1 generation thus making this a more genetically diverse F2?

My problem is, I'm not sure if the parents were true-breeding strains, my gut tells me no, but I'm still not sure.

Any insights would be greatly appreciated. Thanks!

you'll know once you grown them out.

So i did a bit of research and re-read the breeding chapter in Cervantes bible, written by Chimera. Turns out most of the seed you buy from seed breeders are F1 crosses of strains that the breeders have stabilized (hopefully, and apparently not always.) Also the product of two F1 crosses is called a "poly-cross" and its really just a damn grab bag as to what you are gonna get. Traits can be all over the place.

Also, just a personal thought after doing a bit of research on this stuff. The idea of tons of strains is bullshit! Most of the garbage available commercially from seed breeders has not been stabilized. They simply cross plants to pump out seed (and charge us assloads of money for it!) Therefore, every plant of any given strain can be entirely different! Ever wonder why your totally disappointed by your Blueberry? It's because the sought after traits (blue color, signature blueberry smell) are a rare phenotype, that does not show up that often in seed populations!

Granted, there are seed breeders out there that have gone to extreme lengths to stabilize their parent plants that produce their seed stock. However, there are new fucking "strains" on the internet every damn day. This is simply not possible, it takes a LONG TIME to properly breed and stabilize parent plants for a relatively true-breeding variety, and even then there will always be various phenotypes that show up among their progeny. So just cause a seed breeder crossed two different plants and put their names together in a fancy way DOES NOT MEAN that they have necessarily created a new strain. Shop with caution and do your research, make sure your breeders have done their job and are delivering a fine product.

If the seeds that you are gonna breed with aren't true breed strains you will get tones of different genetics from a batch of seeds that you make.
