seeds companies use the same genetics but one. everybody and they mother has a trainwerck cross, a cheese cross, fake pre98' bubba cross, og cross, and diesel cross. but i do know one seed company that uses its own females and has more than three different males to breed with. there's a difference between true breeding and clone only mother breeding, a big difference. not having ppl questioning that your strain is a kush or if it's the real bubba kush means alot. because u telling me that it's kush because of the smell doesnt prove to me that it's a kush strain. og kush aint even a kush but called one. after 15 years of breeding........a seed company cant lie to me. i dont buy dreams.
