This is the dumbest argument.
THE BEST DANK CAN BE GROWN ANYWHERE. PERIOD.
Now an argument about where the best wild weed is, in terms of outdoor soil grow with now additives or special plant food, would make sense. It ignorant to say [insert region/country] has the best indoor grown dank. It might be true that some places have more people growing indoor high quality bud, but this dosent mean its the best.
