I honestly have no idea. I've been growing plants for years, but I've never gotten that much involved in the breeding aspect of it. This is the first time I've even seriously considered trying it.

But here's what I mean by heirlooms. This website has over 1000 heirloom fruit, vegetable, and flower seeds.

i mean, for arguments sake, assuming a male skunk#1 is f1,

bred with a f1 female skunk#1 would produce stable f1 skunk#1 offspring?

or would the ofspring be f2, which needs to be inbred 10x again
to produce f1?

There's a IBL-line thread around here somewhere...

That's got a bunch of stabilized hybrids listed, and more recent strains that are true-breeding

http://boards.cannabis.com/showthread.php?t=80517 this one is about ancient landrace strains that are pure and true-breeding
