Depends on the goal.
Exclusive vs Exclusive is the main distinction in projects.
Exclusive means you only want to fond this one type of plant when you pop seeds.
Inclusive means you want to be able to select from the full spectrum of possibilities when popping seeds.
DJ Short is an example of Inclusive breeding. You can find anything in a pack and select your own keeper.
JJ is an example of exclusive. You’re either gonna fond that one plant, or crap out.
Preservation / Reproduction usually necessitates Inclusive.
