Seed Germination Instructions

for cannabis seeds

soaking seeds icon

Step 1: Soak the seeds

  • Fill a glass with clean, room-temperature water (68-77°F / 20-25°C).
  • Use filtered, dechlorinated, or pH-balanced water to prevent contaminants.
  • Drop the seeds into the water and gently swirl to ensure full submersion.
  • If seeds float, tap them down lightly or leave them to absorb water.
  • Optional: Add 3% hydrogen peroxide (H₂O₂) at a ratio of 1 ml per 100 ml of water to prevent mold and bacteria.
  • Place the glass in a dark, warm location for 2-6 hours (do not exceed 12 hours to prevent drowning).
germination plate icon

Step 2: Prepare the Germination Plate

  • Dampen two layers of paper towel, cotton, or thick toilet paper with clean, dechlorinated water.
  • If using toilet paper, fold multiple plies to ensure adequate thickness.
  • Place seeds evenly between the layers, ensuring they do not touch each other.
  • Towels should be moist but not soaking wet.
  • Set the damp towel on a plate and cover with another plate or place it inside a resealable plastic bag to retain moisture.
  • Store in a dark, warm location (70-78°F / 21-26°C) such as a drawer or cabinet.
  • Check the moisture level every 6-12 hours and add water as needed to prevent drying.
  • Expected Germination Time:
    • Most seeds crack open within 48-72 hours.
    • Some may take 5-6 days to show taproots.
    • Older seeds or seeds with a tougher shell may take up to 10-15 days to sprout.
    • If a seed has not sprouted within 10 days, gently check it for signs of swelling or softening.

Step 3: Monitor Germination

  • Seeds typically crack open and develop a taproot within 48-72 hours, but some may take up to 5-6 days.
  • Older or dormant seeds may take 10-15 days to sprout, especially if they have a thicker shell.
  • Check regularly for signs of mold or fungal growth.
  • If mold appears, replace the paper towel and rinse seeds in a diluted hydrogen peroxide solution (1 ml of 3% H₂O₂ per 100 ml water).
  • The seed is ready for planting when the white taproot emerges and reaches ¼-½ inch (0.6-1.3 cm).
planting seed icon

Step 4: Planting the Seeds

  • Prepare a pH-balanced growing medium (pH 5.5-6.0) such as:
    • Quality soil-perlite mix
    • Coco coir with perlite
    • Rockwool cubes (must be pre-soaked in pH 5.5 water)
  • Plant the seed 2-5 mm deep, with the root tip facing downward.
  • Use containers that are at least 10 cm (4 inches) deep with drainage holes for healthy root development.
  • Lightly cover the seed with soil—do not press down too hard.
  • Spray the top layer with water instead of drenching it.

Step 5: Initial Care for Seedlings

  • Keep the growing medium moist but not waterloggedspray with a spray bottle instead of overwatering.
  • Maintain high humidity by:
    • Covering containers with clear plastic wrap or a humidity dome.
    • Ensuring there is some airflow to prevent mold buildup.
  • Place seedlings under cold white LED or fluorescent lights or in indirect sunlight at 68-77°F (20-25°C).

Step 6: Gradual Exposure to Light

  • Once seedlings emerge and develop their first set of leaves (cotyledons):
    • Slowly introduce them to stronger light sources.
    • Start with low-intensity LED, CFL, or indirect sunlight, then gradually increase exposure.
  • Keep grow lights at a safe distance:
    • LEDs: 12-24 inches (30-60 cm) above seedlings.
    • HPS/MH: 24-36 inches (60-90 cm) above seedlings.
  • If transitioning to outdoor sunlight:
    • Harden seedlings off gradually by placing them outside for short periods each day.

Additional Tips

  • Use filtered rainwater, bottled water, or dechlorinated tap water.
  • Maintain humidity levels between 70-80% for optimal germination.
  • Avoid handling the taproot directly, as it is delicate and can be easily damaged.
  • If using rockwool cubes, pre-soak them in pH 5.5 water before planting.
  • Germination rates depend on strain genetics, seed age, and storage conditions.
  • Seeds may take longer to sprout if conditions are too dry, cold, or hot.

  • Failure to follow these steps may reduce germination success and replacements are unlikely.

    By following these steps, you’ll achieve healthy, vigorous cannabis seedlings ready for strong growth. 🌱
