Growing cannabis in New Zealand can be a deeply rewarding journey, whether you’re cultivating for medicinal purposes or simply exploring plant care as a personal passion. At New Zealand Seeds Bank, we’re here to guide you every step of the way—from seed to harvest.
⚠️ First Things First: Know the Law
Before you start, it’s important to understand the legal status of cannabis in New Zealand. Currently, recreational use remains illegal, while medicinal cannabis can be legally accessed under prescription through licensed providers. Growing cannabis at home without a prescription or special license is still prohibited, so always stay informed and compliant with local laws.

2. Pick Your Growing Method
Cannabis can be grown indoors or outdoors, depending on your setup and the climate.
✅ Indoor Growing
- Greater control over light, humidity, and temperature.
- Grow year-round.
- Use LED grow lights and a grow tent.
✅ Outdoor Growing
- Ideal for spring through early autumn.
- Choose a sunny, discreet spot.
- Watch for pests and mold, especially in humid areas.
3. Germinate Your Seeds
Use the paper towel method:
- Place seeds between damp paper towels.
- Store in a warm, dark place.
- Wait 2–7 days until the taproot appears.
Once sprouted, transplant into soil or a starter medium.
4. Vegetative Stage
In this phase, your plant will focus on leaf and branch growth.
- Light: 18 hours light / 6 hours dark
- Nutrients: High nitrogen levels
- Watering: Keep soil moist, not soaked
5. Flowering Stage
Switch your light cycle to 12/12 (12 hours light, 12 hours dark) to trigger flowering.
- Nutrients: Lower nitrogen, higher phosphorus and potassium
- Keep an eye out for male plants if you’re not using feminized seeds
6. Harvest Time
Ready to harvest? Look for:
- Cloudy or amber-colored trichomes
- Orange or brown pistils
Dry your buds in a dark, cool place with good airflow for 7–14 days. Then cure in jars for smooth flavor and potency.
Final Tips for First-Time Growers
- Keep a grow journal.
- Be patient—cannabis plants take 3–5 months from seed to harvest.
- Respect local laws at all times.
