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.
- Indica-leaning: bushier/compact, keep airflow between colas.
Flowering: ~5 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.

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).

~9–9 weeks seed to harvest.
