The Prairies get hot summers and early frost, which favours autoflowers planted in June and harvested in August. Ontario and Quebec are humid, so pick fast indicas and fast versions that finish by mid September before bud rot sets in. The Atlantic provinces want cold-tolerant autoflowers, and the territories want only the quickest autos, planted the moment frost risk passes.
