To the really hot chilisorterna like heat one can understand when they are growing in many countries with a tropical climate. These chilis seeds can be cumbersome to have to germinate so I have now tried to germinate them in a bit higher heat and high humidity and that the seed had to lie open, not covered and under lighting.
In this test, I would have a constant soil temperature of 32 degrees and a humidity of 72 RH. The seed sprout got open in the sponge cubes (RootIt) I raised the temperature from 28 till 32 degrees thought chilisorterna Fire, Dorsent Naga and Trin. Scorp. Taylor, they only took about. 3 till 4 days for them to germinate.
