Best Ways to Sex Regular Cannabis Seeds (Fast → Faster → Fastest-ish)
🥇 Method 1 — Clone Early, Flip the Clone (Best Overall)
⭐ Your method, and honestly the gold standard
How it works:
1. Grow plant until it has 4–6 nodes
2. Take a small clone (even a tiny one is fine)
3. Root the clone
4. Put the clone straight into 12/12
5. Sex shows in 7–10 days
Why it’s king:
• You don’t stress the main plant
• You keep vegging females while males reveal themselves
• Perfect for keeping moms
• Very reliable
Total time to sex: ~10–14 days
Skill level: Intermediate
My verdict: 🏆 Best balance of speed + control + plant health
⸻
🥈 Method 2 — Flip the Whole Plant Early
Simple, no cloning needed
How it works:
• Veg plant briefly (3–5 nodes)
• Flip entire plant to 12/12
• Look for preflowers
Timeline:
• Sex shows in 7–14 days
Pros:
• Easy
• No cloning equipment
Cons:
• Slows veg momentum
• If female, you’ll need to reveg or accept smaller plants
Good for: Small grows, beginners, quick decisions
⸻
🥉 Method 3 — Stress-Induced Preflowers (Not My Favorite)
Some growers try:
• Extended dark periods
• Slight stress
• Waiting for natural preflowers in veg
Reality check:
• Inconsistent
• Stress isn’t always worth it
• Can delay growth more than it helps
I don’t recommend this unless you’re very experienced.
⸻
Method 4 — DNA Sex Testing (Fastest, If Available)
Technically the fastest
How it works:
• Send a leaf sample to a lab
• Results in 2–5 days
Pros:
• No stress
• No flip
• Ultra accurate
Cons:
• Costs money
• Not available everywhere
Best for: Large or commercial runs
