What is the best way to germinate cannabis seeds?Updated a month ago
The most consistent method is the paper towel method in a warm, dark environment. Keep towels moist, not soaked, and aim for 70–90°F (21–32°C). Most viable seeds show a taproot within 24–72 hours (some take longer).
Step-by-step
- Dampen two paper towels with distilled water and squeeze out any excess water.
- Place seeds between the paper towels; set on a plate and cover with another plate to keep it dark and humid.
- Keep warm (a consistently warm room or a seedling heat mat on “low”).
- Check twice daily. Re-moisten with distilled water if towels start to dry.
- When the taproot is ¼–½ inch (6–12 mm), transfer to your medium root-down and cover lightly.
Pro tips: Label strains, sanitize tweezers before handling, and avoid touching the taproot.
Light isn’t needed until seedlings emerge. Once they break the surface, provide gentle light (18/6 or 20/4 photoperiod) and a moderate amount of airflow.
