Week by week

Germination: Days 1–7

Pop the seed.

Soak in a moist paper towel or plant 1cm deep in light, airy soil.
Keep warm (22–25°C), humid and dark until the sprout appears.
Moist, never soggy.

Seedling: Weeks 2–3

First true leaves.

Gentle light on 18/6, high humidity (~65%).
Tiny waterings near the stem; let the top dry between.
Quarter-strength nutrients at most.

Vegetative: Weeks 4–6 (auto)

Build the plant.

Autoflowers veg briefly then flower on their own, start in the final pot, don't transplant late.
Feed grow (high-N) nutrients; train (LST/topping) for an even canopy.
Hybrid structure, balance height and bush with light training.

Flowering: ~6–8 weeks of bloom

Buds bulk up.

Stays on 18/6 to harvest.
Switch to bloom (high-P/K) nutrients; lower humidity (~45%) to prevent bud rot.
Watch trichomes: mostly cloudy with some amber = peak ripeness.

Flush & harvest: Final 1–2 weeks

Finish clean.

Plain water (no nutrients) the last 1–2 weeks for a smoother smoke.
Harvest, wet-trim, dry slowly (~60°F / 60% RH, 7–14 days).
Cure in jars 2+ weeks, burping daily at first.

~10–12 weeks seed to harvest.

Growing Auto SFV OG outdoors

Sown outdoors in mid May, after the last frost, Auto SFV OG should be ready in late July to early August. That leaves time for a second run: a seed sown by early July finishes around mid to late September.

Drying and curing

Its berry and pine notes come from the most volatile terpenes, the first to go in a warm, fast dry. Dry slowly around 18 °C and 60% humidity for 10 to 14 days and cure in jars to keep them.
