Californiaclimate & growing considerations
California offers one of the longest, most forgiving outdoor seasons in the country. In Southern California plants can stay outdoors for much of the year; across the north — the historic Emerald Triangle of Humboldt, Mendocino and Trinity — the outdoor season runs roughly from spring to late autumn, long enough to finish large photoperiod plants.
The main seasonal risk is coastal fog and late-season humidity, which can invite bud rot on dense flowers near the coast, so airflow and mould-aware genetics matter in foggy zones. Feminized photoperiod hybrids make the most of the long season, while autoflowers let you fit extra cycles or keep a lower-profile grow.
