the blueberry/C99 is one of Joey Weed's strains, I'm assuming ... I didn't grow out that particular strain, but the Joey's 'NL99' I received were very potent, 100% germination, and 100% female (two separate orders of 10 seeds each) ... my fellow med-users and myself were VERY impressed with their potency ... I think you'll be very happy with them ... pre-soak the seeds overnite, they have tough shells ... :smokin:
