I planted 8 non-germinated seeds on the evening of May 5th in soil. They're in a peat pellet container in a PC case with
(2) 13 watt CFL warm lights. 4 of the seeds sprouted on May 12th with a 5th seeds making itself visible in the dirt.
I've read it can take from 3 days to 3 weeks for seeds to sprout without outside intervention. I've also read if they don't sprout by that 3rd week to go ahead and dig em up and try to germinate since you probably don't have that much to loose by trying.

Good luck!
