bc seed company i heard is preatty good and they throw out seeds that are older than 6 months (or so they say) to ensure freshness!! other than that sensi seed is good my friend got some skunk from them and all 10 germenated and were female. other then that i have no personal experiance with seed companys i just get mine from a friend who buys dro by the Oz. so i pay him to give me the seeds out of the nugz and i get them dirt cheap to like .50 a seed. hope that helps.
