Yeh, I know how to get Opium once I have the flower. I just don't know anything about the plant itself, I.E. which strain, veg cycle, flower cycle, etc... If it's just like growing weed, then it wouldn't be too hard.
Also, I would be growing the poppies for personal use, not for sale. I'm a traditionalist when it comes to this drug; I prefer opium. So I wouldn't synthesize it into heroin. (Opium->Morphine->heroin).
