Well , the nederzaad strains are made of positronics strains
The n2005 is a special citral(there where different types not all where sold)
The n2006 is posi citralXgreen dragon
The n2007 is posi citralXgreen dragonXposi cali orange bud
It's 80's weed but the effect is very good
, i think it's a myth that it gets stronger and stronger
get's you stoned , lot's of strains today don't give that type of stone.
Also have original posi afghan and citral at home.
The seeds where supposedly stolen from the desk of wernard and later they surfaced somewhere in amsterdam.
The guy that had the lost seeds went to wernard but wernard didn't want anything more to do with it cuz it brought him lot's of misery(financial also)
So that guy took the seed map home and began making his own strains that are today known as nederzaad.
But the man died september 2008 and the site he had is open but doesn't sell seeds or is gonna sell them in the near future.
The holy box
