Hi Tin, don't worry about your seed pod having one side larger then the other....this happens sometimes. We have had this too, as would many others of us here on the forum. You may find that only one side grows and the other stays small. You may get seed from the larger side and possibly none from the other side, or the smaller side may continue to grow and catch up to the bigger side. Seed pods do they're own thing sometimes. :)

Rachel, thank you. The smaller dropped off and the bigger one continues to grow. I thought that 2 have to grow together to produce seeds.

So true Rachel. I recently had one that stayed small, while the other seemed to make up for it! I got over 100 seeds from one pod.
