Ive never heard that GWS is the original line to every strain. In fact m about 99.9999% sure thats not true. Reason being is there is no first strain. There are different land race genetics that have grown wild since the beginning of time. These are pure, never been cross bread, IBL's. You find indicas in one region of the earth, and sativas in others. All based on distance from the equator and altitude. But the reason I said stick with the tried and true originals is because these are very stable strains and are going to be good for learning while you start you venture of growing. There is a lot of info regarding these common strains and people have been growing them for yrs. So i always recommend that if you have the option to order seeds, get some known ones to begin with, and your grow will most likely be a easier one than say if you tried NYCD your first grow. Just a thought, laterz..
