Habaneros are a little more difficult to start and generally require at least 7 - 14 days to germinate. Some will take upwards of 21 - 30+ days. Soil temperature is the key, to hot or too cold little to no germination. Your soil should remain moist, not too wet, but shouldn't dry out. The temperature of the soil should be between 75 - 85 degrees, with 85 / 86 ideal. Don't take it above 90 at 95+ germination drops off. Planting depth shouldn't be more then 1/4.
Seeds germinate when the soil reaches a specific temperature range surrounding an optimal temperature. The closer the temperature is to the optimal temperature for seed germination, the more seeds will germinate in the shortest amount of time.For example, although 90 percent of all onion seeds will germinate if planted at 32 degrees Fahrenheit, they will take up to 136 days to sprout.By contrast, 99 percent of onion seeds will germinate if planted at 68 degrees Fahrenheit and will take less than five days to grow.eeds germinate when the soil reaches a specific temperature range surrounding an optimal temperature.
