Was sind die Haupt-Strains fuer eine priv. Kollektion

Hi there,
I am an old Ganjamaniac from Germany:oldman:. And I wanna accomplish my own private seedbank/collection. This collection must contain all the different main-types of Ganja: Indica and his turn(high), Sativa and his turn, Haze and his turn, and a good hybrid. I wanna have all this different types of Ganja to have a good smoke for every situation. And perhaps I wanna make my own crosses to be a little bit creative.

So what are the "Must-Have-Strains" for a becomming cropper and breeder (just private not commercial).

PS: What is the best Lemon-Strain?

So what is your advice

THANKS, Martin Haze.:bookworm:
