The 4 Stages Of Cannabis Growth

 

🌱 1. Germination Stage (2–10 days)
• What happens: The seed cracks open, and the taproot (primary root) emerges. A sprout soon pushes up toward the light.
• Ideal environment:
• Light: 18–24 hours/day of low-intensity light
• Temperature: 70–85°F (21–29°C)
• Humidity: 70–90%
• Medium: Moist (not soaked) paper towel or starter plugs


🌿 2. Seedling Stage (2–3 weeks)
• What happens: First sets of true leaves grow, plant develops a stronger root system.
• Ideal environment:
• Light: 18–24 hours/day
• Temperature: 70–80°F (21–27°C)
• Humidity: 65–80%
• Nutrients: Minimal or none (some starter soils have enough nutrients)


🌱 3. Vegetative Stage (3–8+ weeks)
• What happens: Rapid growth in stems and leaves. Plants increase in size, branching out.
• Ideal environment:
• Light: 18–24 hours/day (strong grow lights)
• Temperature: 70–85°F (21–29°C)
• Humidity: 40–70%
• Nutrients: High nitrogen, moderate phosphorus and potassium


🌸 4. Flowering Stage (8–12+ weeks)
• What happens: Plants produce buds. Flowering is triggered by changing light cycles.
• Ideal environment:
• Light: 12 hours light / 12 hours darkness (for photoperiod strains)
• Temperature: 70–80°F (21–26°C)
• Humidity: 40–50% (lower in late flowering to avoid mold)
• Nutrients: High phosphorus and potassium, lower nitrogen
