Before diving in, let’s be clear: germinating cannabis seeds is illegal in the UK. However, in Germany, where our good friends are growing these seeds legally for personal use, we’re able to share their experience. All it took was switching the equipment to EU power standards, and they were ready to go! Who knows, one day this could become legal in the UK too!

Autoflowering strains like Zookies are an excellent choice for growers due to their ease of cultivation and shorter growth cycle. Below is a comprehensive guide based on our contacts’ successful setup.


Equipment Overview

This grow uses the following setup:


Zookies-Cannabis-Grow

Week-by-Week Guide

Drying and Curing the Harvest ?

Once your Auto Zookies plants have been harvested, proper drying and curing are essential to preserve flavour, potency, and overall quality. Rushing this step can lead to harsh smoke, reduced potency, and poor storage longevity. Follow this guide for the best results:


Drying Your Buds ?

  • Trim and Hang: After harvesting, remove excess fan leaves and hang the branches upside down using a drying hanger in a well-ventilated drying area.
  • Light Conditions: Keep the drying area in complete darkness to protect cannabinoids and terpenes.
  • Temperature: Maintain a stable temperature of **18-21°C (65-70°F)**.
  • Humidity: Maintain **50-60% relative humidity** for slow, even drying.
  • ⏱ Time: Allow the buds to dry for **7-10 days**, or until the stems snap cleanly instead of bending.

Curing Your Buds ?

  • Jar the Buds: Once dried, trim the buds from the branches and place them in airtight glass jars (e.g., mason jars) or tins.
  • Light Conditions: Store jars in a cool, dark place to preserve quality and prevent degradation of cannabinoids and terpenes.
  • Temperature: Keep the curing environment at 20-21°C (68-70°F).
  • Humidity: Use humidity control packs (e.g., Boveda 62%) to maintain ideal moisture levels within the jars.
  • ⏱ Burping:
    • Week 1-2: Open the jars for 15 minutes daily to release built-up moisture and exchange fresh air.
    • Week 3-4: Reduce burping to every 2-3 days for approximately 10 minutes per session.
    • Week 5 and Beyond: Burp the jars once a week for 5-10 minutes to maintain freshness and monitor for any changes in humidity.
  • ⏱ Time: Cure for a minimum of 2-3 weeks, though curing for 4-6 weeks will significantly enhance flavour, aroma, and smoothness.

Pro Tips ?

  • Monitor Humidity: Avoid humidity above 65% to prevent mould and below 55% to avoid over drying.
  • Longer Cures: For the best results, cure your buds for up to 2 months. The longer cure improves flavour complexity and smoothness.
  • Avoid Plastic Bags: Never cure in plastic bags, as they can trap unwanted moisture and degrade the quality.

Final Notes: Avoiding Issues and Monitoring Plant Health ?

As you move through your grow, keep a close eye on your plants to ensure they remain healthy and stress-free. Cannabis plants, especially autoflowering strains like Zookies, can be sensitive to environmental changes and growing conditions. Below are key points to watch for and tips to address potential issues:


Watch for Light Burn ?

  • Signs of Light Burn: Yellowing or browning at the tops of the plants, curling leaves, or faded colouring on the uppermost leaves.
  • Adjust Light Intensity: If you notice signs of stress, reduce the light intensity by 10-20% using the dimmer dial.
  • Maintain Proper Distance: Ensure the light is at least 35-45 cm (14-18 inches) above the canopy during the flowering stage.

Other Potential Issues and Solutions ?

  • Overwatering:
    • Symptoms: Drooping leaves, yellowing, or stunted growth.
    • Solution: Allow the soil to dry out between waterings. Use smaller, consistent amounts of water to avoid saturation.
  • Underwatering:
    • Symptoms: Wilting, dry or crispy leaves, and slowed growth.
    • Solution: Water thoroughly when the soil feels dry about 2-3 cm below the surface.
  • Nutrient Burn:
    • Symptoms: Brown, crispy leaf tips or edges caused by excess nutrients.
    • Solution: Flush the soil with pH-balanced water to remove excess nutrients. Adjust nutrient levels and monitor closely.
  • Humidity Problems:
    • High Humidity: Can lead to mould and mildew. Use a dehumidifier to maintain ideal levels (50% during flowering).
    • Low Humidity: May cause slow growth or dry leaf edges. Use a humidifier to maintain 60-65% during vegetative growth.
  • Heat Stress:
    • Symptoms: Leaf edges curling upwards, discoloration, and slowed growth.
    • Solution: Ensure proper ventilation and maintain temperatures between 20-26°C (68-79°F).
  • Pests:
    • Symptoms: Visible insects, bite marks on leaves, or sticky residue on plants.
    • Solution: Inspect plants regularly. Use organic pest control solutions like neem oil or sticky traps to manage infestations.

Final Pro Tips for a Successful Grow ?

  • Keep a Grow Journal: Track light settings, nutrient schedules, and plant responses. This helps identify patterns and fine-tune future grows.
  • Adjust to Your Plants’ Needs: Every strain is unique. If your plants show stress, respond by adjusting light intensity, watering frequency, or nutrient levels.
  • Patience is Key: Autoflowers grow quickly, but rushing through the process can reduce yield and quality. Take the time to monitor and care for your plants properly.
  • Learn and Improve: Each grow is a learning experience. Experiment with techniques and adapt to improve your results each time.

By carefully observing your plants and making adjustments as needed, you’ll be on your way to a healthy and rewarding harvest. Enjoy the process, and happy growing! ??
