the breeder does matter. if you don't get seeds from reputable breeder you don't even know what your getting(f2's, f3's, f6's) and with ten plants you could get 10 different phenos! if you get seeds from a well know, experienced breeder then you plants will be more unform and an overall better cross. i have grown ww from an unknown canadian breeder and my results were good but not the best. i also grew dutch passion ww's and the results i got were so much better that there was no comparison. could be a coincedence i guess....
