What strain for northern grow?

Hey,
I live in northern Quebec and was wondering what strain should I grow. Looks like we're going to have a killer summer so it's all good. So far I'm getting some vanilla kush. I'd like to have some strains that will give me a strong head buzz and good yield. Looking for 1 strain of strong sativa and 2 of purple. I want to get royally baked since I've become somewhat immune to the grass we have around here . Going for 30-40 plants. So any advice would be greatly appreciated.

Thanks,
JR

Well I think I'm going to go with:

1. Barneys Farm Vanilla Kush Feminized
2. Serious seeds white Russian feminized
3. G13 labs purple haze feminized
4. Dutch Passion Purple #1 Feminized Seeds
5. Green House Seeds Super Lemon Haze Feminized

Any thoughts? Also ordering them all from the attitude seedbank.

Try the Superlemonhaze.Its a hardy plant.
