I'm no expert, but from what I have seen, most of my seeds have germinated between 24-48 hours. are you using the paper towel method? I was told, and have successfully done, to put them in distilled water for 24 hours, then transfer them into a moist paper towel. it's best to keep the towel in a dark place, and warm. a $24 heating pad that I got at the local grow shop has worked very well in keeping them warm. good luck. i haven't got much past the seedling stages yet, but this worked very well for me as far as germinating goes.
