Northern Lights Autoflower Mastery: The Art of Growing

Growing your own cannabis is a gratifying endeavor, and Northern Lights Autoflower is a strain that is particularly suited for both beginners and experienced growers alike. With its robust genetics and forgiving nature, this strain has gained immense popularity. In this detailed guide, we will explore every facet of cultivating Northern Light Autoflower, from ideal environmental conditions to maximizing yields. Whether you’re a novice or a seasoned indoor cultivator, this article will provide you with valuable insights on nurturing your cannabis plants to their fullest potential.

Ideal Temperature and Humidity Range

  1. Temperature Range: Maintaining the correct temperature is paramount for healthy Northern Lights autoflowering plants. During the day, aim for temperatures between 21°C to 29°C, while nighttime temperatures should slightly drop to around 14°C to 21°C. Consistency is key to preventing stress-related issues and encouraging vigorous growth.
  2. Humidity Range: Proper humidity levels are crucial at different growth stages.  During the vegetative phase, aim for a humidity range of 40% to 60%. As your plants transition into the flowering stage, lower the humidity to around 40% to prevent mold and mildew development.

Nutrition Feeding Schedule and Soil Mix

  1. Soil Mix: Begin with a high-quality, well-draining potting mix that is specifically designed for cannabis cultivation. Alternatively, you can create a custom mix using peat moss, perlite, and compost. Ensure that the pH level of your soil is within the range of 5 to 6.
  2. Seedling Stage: When your Northern Light Autoflower seeds sprout, use a light nutrient solution designed for seedlings. Dilute it to half the recommended strength and feed your plants every 2-3 days, keeping a close eye on pH levels.
  3. Vegetative Stage: Switch to a nutrient formula with higher nitrogen (N) content for healthy vegetative growth. Monitor pH levels and gradually increase the nutrient concentration as your plants mature.
  4. Flowering Stage: Transition to a bloom-specific nutrient mix with higher phosphorus (P) and potassium (K) levels to promote flower development. Reduce nitrogen levels to discourage excessive foliage growth. Adjust pH to maintain the optimal range.
  5. Feeding Schedule: Generally, it’s advisable to feed your Northern Light Autoflowering plants every 2-3 days. However, always observe your plants closely and adjust the schedule or nutrient concentration based on their specific needs.

Pest Management

  1. Preventative Measures: Preventing pests is often more effective than treating an infestation. Maintain a clean growing environment and regularly inspect your plants for any signs of trouble.
  2. Beneficial Insects: Consider introducing beneficial insects like ladybugs or predatory mites into your indoor garden. They can help control common cannabis pests such as aphids, spider mites, and whiteflies.
  3. Organic Solutions: In the event of a pest issue, opt for organic solutions like neem oil or insecticidal soap. These treatments are less harmful to your plants and the environment compared to chemical pesticides.

Low Stress Training (LST)

Low Stress Training is an essential technique for increasing your Northern Lights Autoflower yield while maintaining manageable plant size:

  1. Early Training: Start LST when your plants have at least four nodes. Gently bend the main stem down and secure it horizontally using soft plant ties. This encourages lateral growth and prevents your plants from becoming too tall.
  2. Tie Down Side Branches: As your plants continue to grow, repeat the process with side branches that are reaching for the light. This creates a more even canopy, promoting uniform bud development.
  3. Regular  Monitoring: Keep a close eye on your plants and adjust the ties as necessary to ensure that the branches remain in their desired positions.

Maximizing Yield

To get the most out of your Northern Lights Autoflower plants, follow these additional tips:

  1. Select Premium Seeds: Begin with high-quality autoflowering seeds from reputable sources like Zen Seeds Bank. Genetics play a significant role in yield and potency.
  2. Optimal Lighting: Invest in high-quality LED grow lights to provide your plants with the correct spectrum and intensity of light throughout their life cycle.
  3. Lighting Schedule: During the vegetative stage, maintain a light schedule of 18 hours on and 6 hours off. When transitioning to the flowering stage, switch to 12 hours on and 12 hours off.
  4. Pruning and Defoliation: Remove lower growth and smaller buds that won’t receive enough light. This redirects energy to the top colas, where the largest and most potent buds will form.
  5. Nutrient Flushing: Two weeks before harvest, flush your plants with clean, pH-balanced water. This process removes any residual nutrients and enhances the final flavor and aroma of your buds.


Cultivating Northern Lights Autoflowering cannabis is an enriching experience that can yield a bounty of top-quality buds. By adhering to ideal environmental conditions, a precise feeding schedule, effective pest management, mastering the art of Low Stress Training, and implementing yield-boosting techniques, you can ensure a successful harvest.
