⏱️ How Long Does It Take to Grow Autoflower Seeds?Updated 3 months ago
Autoflowering cannabis seeds are known for their speed — perfect for growers who want a quick harvest without the hassle of changing light cycles 🌞🌒
Here’s what to expect when it comes to the growing timeline for autoflowers ⤵️
🗓️ Average Autoflower Grow Time
Most autoflowers go from seed to harvest in 8 to 12 weeks — much faster than photoperiod strains!
Here’s a rough breakdown:
| Stage | Timeline |
|---|---|
| Germination | 1–5 days |
| Seedling | 1–2 weeks |
| Vegetative phase | 2–3 weeks |
| Flowering phase | 5–7 weeks |
| Total time | 8–12 weeks ⏳ |
🌿 Factors That Affect Autoflower Timing
While autos are designed to be quick, a few things can make them take a little longer — or finish faster:
Strain selection (some take 10+ weeks, others finish in 7)
Light quality and hours — 18–20 hours of light per day is ideal 💡
Environment — temperature, humidity, and airflow all matter 🌡️
Pot size — start in your final pot to avoid transplant shock 🪴
Stress — overwatering, poor pH, or nutrient issues can slow them down 🚫
💡 Bonus Tip: Don't Wait for Perfect Amber Trichomes
Because autos often flower so fast, waiting too long to harvest can lead to degradation in potency. Keep a close eye on trichomes during weeks 8–10 — many autos are ready when they're mostly cloudy with just a hint of amber 🔬
