Just remember, not all seeds will germinate, no matter the method, some are just duds.
They can also take up to 7 days to germinate, the phase of the moon can have a big bearing on this, believe it or not.
I always germinate between the New Moon and the Full Moon, that is, first and second quarter, and experiments I have done have proved this to be the most fertile period and repeatable, year after year, as I have been germinating at this time period for 30+ years.
