7 days is quite a long time, but not unheard of. It can take 2 weeks for a seed to sprout for an old bean, but a fresh one from Nirvana should sprout in a few days.
put a fresh seed in a shot glass of room temp water (80F or higher) If your room isn't 80F, then place the shot glass on your modem, router, etc. Let the bean sink (12-24 hours), then place in moist paper towel in a cup and set on modem. Within 12-24 hours, a taproot will show, now it is time to plant.
