strains that where lost are are now being found again.. Many of the strain back in the day where every bit as good but where lost for reason we wont ever know. We can be sure that gg#4 will be here to stay. From the Silver haze I remember back then the buds where silver from the tric's and was so sticky it was not easy to get a blunt to burn good. The SH of today is not even close to the same.
What i don't understand is how it is possible for there to be a true male resulting from that kind of pollination.
My thinking is you never can get a "true male". But I think what you can get is a male dominate hermie if that makes since. Now the question is, is male part of the equation strong enough to deliver stable pollen.
