Ya it normally takes me 2 days to germinate and about 2 days for it to sprout. But some may sprout in1 day some may take a little longer. at least give them a week before you give up but they should sprout before that.
Just on a note: I had a bagseed once that took a week and a half. I put the seed in soil and waited, and waited, and wiated. Up came a plant and turned out to be a female. Healthy one too. Little bit of a slow start. but she made it.
