The Complete Growth Cycle of Feminised Cannabis Seeds

Growth Cycle of Feminised Cannabis Seeds

Growing feminised cannabis seeds can be a truly rewarding experience. These seeds are prized for producing only female plants, ensuring a bountiful harvest of buds. Let’s delve into each stage of their growth cycle, and I’ll share some personal tips and insights to help you along the way.

Seedling Stage (0-2 weeks)

This journey begins with the seedling stage, lasting from 0 to 2 weeks. It’s a critical time as the plant establishes its roots and first leaves.

Lighting: Provide 18-24 hours of light per day. Young seedlings thrive under continuous light, which supports rapid growth and strong root development.


  • High Humidity: Seedlings love a humid environment. Aim for a humidity level of around 60-70% to prevent drying out.
  • Gentle Watering: Be careful with watering. The soil should be moist but not waterlogged. Overwatering can lead to root rot, while underwatering can stunt growth.

I remember my first time nurturing cannabis seedlings. The excitement of seeing those tiny leaves unfurl was immense, but I quickly learned the importance of balanced watering after a few early mistakes.

Vegetative Stage (3-8 weeks)

In the vegetative stage, your plants will start to grow rapidly, developing sturdy stems and lush foliage.

Lighting: Continue providing 18-24 hours of light per day. This promotes robust growth and prepares the plants for the next stages.


  • Rapid Growth: This period sees vigorous growth. Make sure your plants have enough space to expand and thrive.
  • Nutrient Needs: Increase nutrient levels to support this growth spurt. Use a balanced fertiliser with higher nitrogen content to promote healthy leaf and stem development.

During this stage, I’ve found that keeping a close eye on nutrient levels makes a significant difference. It’s amazing how a well-fed plant can flourish!

Pre-Flowering Stage (9-10 weeks)

As your plants enter the pre-flowering stage, they will begin to show the first signs of sexing. While feminised seeds should produce female plants, it’s still important to monitor closely.

Lighting: Maintain 18-24 hours of light per day. Consistent lighting helps the plants prepare for flowering.


  • Monitor for Sexing: Check for pre-flowers at the nodes. Feminised seeds should produce female plants, but it’s always good to double-check.
  • Prepare to Switch Light Cycle: Get ready to switch the light cycle to induce flowering.

I always feel a bit of anticipation at this stage, eagerly checking for those first signs of flowering. It’s a crucial time to ensure everything is in place for the next big phase.

Flowering Stage (11-18 weeks)

The flowering stage is where your hard work begins to pay off, as buds start to form and mature.

Lighting: Switch to 12 hours of light and 12 hours of darkness per day. This change in the light cycle triggers the flowering process.


  • Bloom Nutrients: Use bloom nutrients to enhance bud production and quality.
  • Reduce Humidity: Lower the humidity to around 40-50% to prevent mould and mildew, which can damage your buds.

Watching the buds develop during this stage is incredibly satisfying. Each day brings noticeable changes, and it’s crucial to keep the environment stable to avoid any issues.

Harvest (19-24 weeks)

The final stage of the growth cycle is harvest time, a critical period where timing is everything.

Lighting: Maintain the 12/12 light cycle until the harvest. Consistent lighting ensures the plants stay healthy until the end.


  • Monitor Trichomes: Check the trichomes on your buds with a magnifying glass or microscope. Harvest when they are mostly milky white with some turning amber for the best potency and flavour.
  • Preparation: Prepare your drying area to ensure a smooth transition from harvest to curing.

When it comes to harvest, patience is key. I’ve learned that waiting for the perfect trichome colour can significantly impact the final product’s quality and potency.

Additional Tips for Growing Feminised Cannabis

  • Proper Nutrient Schedules: Ensure you follow proper nutrient schedules for each stage to avoid deficiencies and promote healthy growth.
  • Monitor Environmental Conditions: Keep a close eye on temperature and humidity levels, adjusting them as needed to create an optimal growing environment.
  • Responsive Adjustments: Be attentive to your plants’ needs and make adjustments based on their responses. Each strain might have slightly different requirements.

By following these guidelines, you can ensure a healthy growth cycle for your feminised cannabis plants. Adjust nutrient levels and environmental conditions based on the specific needs of your plants, and you’ll be rewarded with a successful harvest.
