As @SeminoleSeeds mentioned it came from I think New Brunswick and that it was possibly an Afghan Haze pheno that was worked into what we now know as R2 here.
My experience was it always finished nice and early. I remember growing a bunch out and they’d be almost all female from what I assume was late flower intersex and subsequent pollination but I rarely found seeds in the stuff I grew out.
It pops up at the dispensaries sometimes and it’s always way danker than what I remember (medium potency, myrcine flavor and aroma) so I’m not sure where the strain is at today compared to what I remember.
