best strain for northern hemispheres

so I grew some white widow outdoors this summer in pots. They were amazing but they started to flower really late. I have them inside now and they still are not finished flowering. There has already been snow where I live and If i am growing outside I need something that takes a bit less time to finish. Does anyone have any suggestions? I would like to plant in late may and be finished in september sometime.

train wreck,hashplant,maybe big bud

Nirvana has some strains like early girl, or early skunk that finish anywhere form mid september to the 1st of october. Check those out.

If you choose nirvana you have to remember there strains are very unstable and wont always turn out how you want them to. Pick a few f1 strains and try them out you'll be much more pleased. You have snow wow I live in Minnesota and I havent scene any snow you must be in canada or the mountians.

thanks guys. yeah it was a fluke kind of snow but they do happen up here.

im looking for friends in the minnesota area

Im in the northern part os the usa and some strains that have been great and actually finish on time like the breeders say are Easy sativa from female seeds. Barneys Blue cheese they have them in female seeds. Actually alot of barneys strains finish by the end of september so if your looking for a potent reliable strain check out barneys.
