Depends, the orange barb parent I grew outdoors and it was quite large, but my outdoor plants are always large. The crosses have stayed relatively small, I topped and LSTd, they're manageable for sure. I just chopped the seeded plants a few days ago and tried to pull out seeds wet but it's a hassle, drying them now because that's easier. Looks like I'll get 1 or 2 hundred seeds from each!
Edit: 25 percent of the seeds from this current f2 cross will be autos, which are always small. I also have the f1 cross and none of those should be autos, if I'm doing my punnet square correctly
