"I suspect that I'd continue to raise my own seedlings even without a good excuse, because I enjoy the process, but when I stop to think about it I realize that there are all kinds of good reasons for nurturing one's own plants from seed."

SEED STARTERS HANDBOOK by Nancy Bubel

I never knew seeds have dormancy problems I thought when it failed to germinate then I considered they are dead seeds and I threw them all. This book explain something about germination and breaking dormancy of seeds. It's very interesting to me so I share here.

"Here is what the experts have discovered.

Temperature. Chilling the seeds often breaks dormancy.

Light. Subjecting the seeds to light - even a dim continuous light or a sudden bright photoflash - will sometimes help, especially with lettuce. Germination depends on the total
amount received. The dimmer the light, the longer the necessary exposure.

Red light. Exposure of some seeds to red light (600 nanometers) promotes seed germination. Experiments with lettuce bear this out. However, far-red light (730 nanometers) has been found to inhibit seed germination. Practically speaking, this means that seeds that are
difficult to germinate will often dormancy better under fluorescent plant lights (see chapter 10). Some seeds won't germinate when shaded by leaf cover, probably because the leaves filter out helpful rays while allowing the inhibiting far-red light to reach the seeds.

Dormancy is seldom a problem with vegetables seeds, except for some heat-sensitive seeds like lettuce and celery. Beans, mustard, and many other vegetable seeds never go dormant. Carrots and parsnips do need month of afterripening following harvest before they'll germinate. Seeds you've purchased have had time, of course, to undergo any necessary afterripening in the months between collection and planting. Dormancy is not an uncommon problem when trying to germinate seeds of wildflowers, trees, or shrubs."

So I think it is possible the chili seeds are also having problems of dormancy.

Share you knowledge and experiences will be appreciated.
