I read that Wikipedia article 100% incorrectly, missed the ‘west of the’ before Himalayas. Legitimately, thanks!

If I were to guess, probably because they’d be left to their own devices rather than carefully managed for higher THC content and flavour profile.

Could be good ol’ fashioned landrace Hindu Kush, though (which would still be mids, but I’d smoke it) - why do you think that’s what the strain’s called?

Edit: The Hindu Kush is not part of the Himalayas. This comment will remain as is, as a reminder to read stuff carefully.
