Darkness isn't necessary but heat is when it comes to pepper seeds. Thus the so-called "baggie method" is good for them if you don't have a heat pad for germination. The baggies method calls for seeds between damp paper towels, into a zip lock bag, placed in the sun for heat. Check frequently. Once sprouted transfer the germinated seed into a ready to go small container of damp potting mix and lightly cover it with more mix.

Check the forum FAQs for more details.

So i should take it out from the plates and seal in a ziplock? it gets pretty hot outside where i am. leave it out there overnight?

Placing the bag on top of a cable box or fridge works too. Anyplace warm.

Rodney

Yeah warm, not cooking hot. Why are you doing it outside?
Especially if it is so hot. A sunny window works just fine or like
Rodney said many use top of TV or near a heat vent or any place indoors
that is extra warm.
