+2 to the comments above. If you want something you are sure is going to grow true, then I would get seeds directly from the source. If you don't care if it's a cross with who knows what, then seeds from purchased/obtained pods or seed trade with someone.
For next year I have some "original" seed from their sources. Primo is one of them. The other stuff is from pods I purchased. If they don't grow true, I'm hoping for some cool cross to pop up.
Good luck!
