No worries man and it's no dumb question we all had to start somewhere. You'll learn a ton on this forum over time. We are offering regular sex seeds only and ship in the US only. Yes we focus on first time crosses (f1's (IBL x IBL)). It kind of depends on the cross (from what I've seen so far) on the number of phenos/variability. From what I've read, most folks seem to say you get the highest variability in the f2 generation. I haven't had enough personal experience with f2s (yet) to see how much more diverse they are. Hope that helps. I'm still learning all the time and glad to share with everyone here what I've learned.
