You don't need perfect weather. Jeebus. It's as if you don't understand how things can be grown so you think nobody can.Folks have been trying to grow tobacco in other parts of the country for 400 years now. They don't have the combination of weather and soil needed.
Weed can be grown anywhere though, even in closets like I mentioned earlier.
If weed is legalized there will be a billion sites out there showing you how as well.
Read the fricking sites. Other parts of the nation can grow tobacco. Even you could, if you wanted. You can even legally sell a certain amount without taxation.
And lastly, the best stuff (MJ) comes from "professional" producers (in Canada is where the best stuff in the West gets produced).
