It depends what northern lights you're looking for.
Looking for pinesol type smells from NL2, chem #4 or the "pure" OG cuts, s1/2/3, are basically the modern version. A touch of hashplant tossed into both, likely.
NL5 sweet-fruit-citrus type stuff is out there but not much of it has as nice of a buzz as NL would. So much of that terpene profile is filled with stuff geared towards hash because heavy smokers can't smoke enough of the flowers to get their desired effect.
There's good stuff coming out today but there's a reason why people are yearning for the old stuff.
