Hello, I made a step by step guide on how to germinate the stubborn reticulata seeds. I have successfully germinated these seeds in 2-3 weeks.
I have seeds in various stage to make this video.

1. Soak your seeds in clean water for 1-2 day
2. Put your seeds in clean damp paper towel. Keep it in warm dark place. Temperature must be above 85F. I keep mine in the drawer underneath the heat mat to keep it warm.
Do not go over 98F.
3. If your seeds do not show sign to germinate after a week or two. You can trim the tip of the seed carefully. Exposing the white seed inside. Do not cut off any part of the white seed.
4. After trimming, soak the seeds in clean water again for 1-2 hours. Do not soak over night or it could rot.
5. Put the seeds back into the clean damp paper towel. Keep it in warm dark place above 85F. You could see sign of germination as early as 2 days.
Important note: Temperature must be above 85 F or your seeds could get moldy. Do not soak over night after trimming.
I germinated 10 out of 12 seeds this way. I know it is a small sample but I think it work well. Let me know if it work for you as well.
Update February 8th
This is 2 days after I trimmed Lemon Reticulata on the video. You can see the root already pushing out
