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 4–7 (you control length)
Build the plant.
- Photoperiod: keep 18/6 as long as you want size, then flip to 12/12 to begin flowering.
- Feed grow (high-N) nutrients; train (LST/topping) for an even canopy.
- Indica-leaning: bushier/compact, keep airflow between colas.
Flowering: ~7–9 weeks of bloom
Buds bulk up.
- Now on 12/12. Expect a 2–3 week stretch early, give headroom.
- 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.
~14–17 weeks (plus veg time).
Growing Kerosene Krash outdoors

That is late in the season: autumn rain and cold bring bud rot, so it suits a greenhouse, a dry southern spot or an indoor grow better than an open northern garden.
