Outdoor Grow Switzerland — Climate, Strains, Timeline

Q: Hiding from neighbors?

Legally (CBD <1%) not required. Socially often sensible — the plants look identical.

Swiss summers are short but intense. With the right choice of strains, yields of 100–500 g per plant are achievable.

TL;DR: Sow indoors in mid-April, transplant outdoors after the Ice Saints. Harvest September–October. Autoflowers: May → August/September. Strain choice is crucial: mold-resistant, short flowering time.

Climate Zones in Switzerland

Mittelland (ZH, BE, BS): 4–5 sunny months, wet autumns → mold risk. Choose early-flowering strains.

Ticino, Valais, Lake Geneva region: Mediterranean climate, season possible until early November.

Pre-Alps/Alps >800 m: shorter season, less humidity. Autoflowers are ideal.

Outdoor Strain Selection

Frisian Dew, Durban Poison, Early Skunk: mold-resistant and early-maturing.

Autoflowers (Swiss Dream Auto, Fast Buds): 10–11 weeks seed-to-harvest.

Avoid: pure Sativas with >10 weeks of flowering in the Mittelland.
