🌱 How Long Does Northern Lights Autoflower Take From Seed to Harvest?Updated 7 hours ago

Northern Lights Autoflower is known for its quick and easy grow cycle, making it a favorite among both beginners and experienced cultivators.

⏳ Total Grow Time

On average, Northern Lights Auto takes about 8–10 weeks from germination to harvest. This includes:

• Seedling stage: ~1–2 weeks

• Vegetative stage: ~2–4 weeks (overlaps with early flower in autos)

• Flowering stage: ~5–7 weeks

🌸 When to Start Flushing

Flushing is typically done during the last 1–2 weeks before harvest. Signs it may be time to start flushing include:

• Most pistils (hairs) have darkened and curled in.

• Trichomes are mostly cloudy with some amber (use a magnifying glass or jeweler’s loupe).

• Buds are firm and have reached their expected size.

💡 Tip: Always check trichome color rather than relying solely on the calendar — environmental factors can make plants finish a little earlier or later than average.
