Good ideas everone! And it seems some of you are already working on something, cool!
It's true that in order to breed spectacular hybrids, one must use spectacular plants. I don't like racy stuff either, it has it's uses in meditation but my grail would be a daytime smoke.
Ofcourse you would end up with euphoric plants if you only used anti-anxiety strains like Nepal, Ethiopian Highland, Kerala or Oaxacan but to me there has to be variation. Put some anti-anxiety strains in the mix but also a bit of something that will blow your mind and you might find something special in the offspring. There are psychedelic shroom like sativas, dreamy euphoria inducing sativas and crystal clear let's do things sativas.. Lot's of cool combinations to try out!
I was also considering a Nepalese building block, that wouldn't be bad at all! Or malawi gold for that matter.
Paki sativa from bohdi's medicine buddha, Oaxacan, Ethiopian, n perhaps Burmese. A psychedelic four way could be Zamal/thai x Angola/Thai.
