landrace varities that finish 50* N ???

i can only give you my first hand experience. it's called Early Maroc 100% sativa . the seed was germinated on the 8th of february and i harvested it on the 28th of june 2017. latitude 40N after 2 weeks of curing i got 100gr of dry buds. hope it helped. it's a real fast finisher. not an auto
