Growing sativa seeds south of the equator flips the whole calendar and the long flowering lines actually suit the season better. Planting in September or October gives a long summer veg and the plants flower through a warm autumn into April or May, which is far kinder to equatorial genetics than a European October. The hemisphere specific schedules on https://hazesativaseeds.com (https://hazesativaseeds.com) are one of the few places I have seen this laid out properly instead of just assuming everyone is in the north. Southern African lines in particular seem built for that pattern.
