2 | Understanding Cannabis Seeds Genetics.
Genetics determine a plant’s traits, including:
- Flowering time
- Height and structure
- Cannabinoid and terpene profiles
- Resistance to pests and environmental stress
Genotype: The genetic blueprint within the seed
Phenotype: How those genes are expressed in the plant
Premium genetics allow growers to predict plant performance, minimising surprises during growth and maximising yield.
3 | Types of Cannabis Seeds.
3.1 Feminised Seeds
Produce only female plants
Ideal for consistent yield and potency
Popular for indoor and small-scale growing
Include both male and female plants
Essential for breeding and preserving genetics
Slightly higher risk of male plants reducing harvest
Flower automatically regardless of light cycles
Compact, fast-growing, and ideal for multiple harvests
Modern breeding ensures stable genetics and high potency
4 | Preparing Cannabis Seeds for Planting
Check Seed Quality: Healthy seeds are firm, dark, and free of cracks.
Germination Methods:
Paper towel method
Direct soil planting
Starter cubes or hydroponic setups
Optimal Conditions:
Temperature: 20–25°C
Humidity: 70–80% during germination
Early Care: Handle seeds gently; avoid overwatering.
A strong start improves plant health and maximises growth potential.
5 | The Vegetative Stage: Growth Foundations
During the vegetative stage, plants focus on root and leaf development. Proper care ensures larger, healthier plants for higher yields.
Key Factors:
Lighting: 18–24 hours of light per day for indoor grows
Nutrients: Balanced nitrogen, phosphorus, and potassium
Watering: Consistent but not excessive; maintain soil aeration
Training Techniques: Low-stress training (LST) or topping to increase bud sites
6 | The Flowering Stage: Maximising Bud Production
Flowering determines your final yield. Auto flowering and feminised seeds respond differently, but all benefit from:
Lighting Adjustments: Photoperiod strains require a 12/12 light cycle
Nutrient Focus: Higher phosphorus and potassium for bud growth
Pruning and Maintenance: Remove lower growth that won’t develop into quality buds
Environmental Control: Maintain 20–25°C temperature and 40–50% humidity to prevent mould
7 | Environmental Factors That Affect Yield
Temperature: Avoid extremes; stress reduces bud size
Humidity: Too high causes mould; too low stunts growth
Airflow: Proper circulation strengthens stems and reduces disease
Space Management: Compact strains like auto flowers are ideal for limited space
8 | Common Mistakes That Reduce Yield
- Choosing poor-quality or unverified seeds
- Overwatering or underwatering
- Ignoring nutrient requirements
- Poor lighting or ventilation
- Failing to monitor environmental conditions
- Neglecting pruning or plant training
Avoiding these mistakes ensures your seeds reach their full potential.
