Cannabis Seeds: The Complete UK Buyer’s Guide 2025.
Choosing the right seeds is one of the most important decisions any grower can make. With hundreds of strains, dozens of breeders, and multiple seed types — feminised, auto flowering, high-CBD, and regular — finding the perfect match can feel overwhelming.
At Discount Cannabis Seeds, we’ve helped thousands of UK growers find the ideal seeds for their growing conditions, space, and goals. Whether you’re cultivating indoors, outdoors, or just starting your first grow, this detailed guide will help you make the right choice — and avoid common mistakes.
Let’s break it down step by step so you can confidently choose the seeds that fit your setup and growing style.
1. Understanding the Different Types of Cannabis Seeds
Before you choose your strain, it’s essential to understand the main seed types available.
Feminised seeds are bred to produce only female plants, the ones that develop flowers (buds). They’re the top choice for most growers because they eliminate the risk of male plants pollinating your crop.
Best for: Indoor and outdoor growers who want maximum yield and efficiency.
Advantages:
- Guaranteed female plants
- Higher yield potential
- Less wasted space and resources
⚡ Auto flowering Cannabis Seeds
Auto flowering seeds automatically switch from vegetative to flowering phase after a few weeks, without needing a change in light cycles. They’re fast, compact, and ideal for beginners or growers with limited space.
Best for: Growers looking for fast, easy harvests.
Advantages:
- Ready to harvest in 8–10 weeks
- Can be grown year-round indoors
- Perfect for discreet outdoor growing
Regular seeds produce a mix of male and female plants, making them ideal for breeders who want to create new hybrids or collect pollen.
Best for: Experienced growers and breeders.
Advantages:
- Full genetic diversity
- Great for breeding projects
High-CBD strains have become increasingly popular for those who want the therapeutic benefits of cannabinoids without strong psychoactive effects.
Best for: Wellness growers and CBD product makers.
Advantages:
- Low THC, high CBD
- Calming, relaxing effects
- Potential medicinal applications
2. Indica vs Sativa vs Hybrid — What’s the Difference?
When choosing seeds, knowing your strain type is crucial.
🌙 Indica Cannabis Seeds Strains
Originating from the Hindu Kush mountains, indica plants are short, bushy, and quick to flower. They deliver deeply relaxing, body-heavy effects.
Best for: Night-time use, stress relief, or relaxation.
Popular examples:
Northern Lights Cannabis Seeds.
☀️ Sativa Cannabis Seeds Strains.
Sativas are tall plants with longer flowering times. They provide uplifting, cerebral effects that spark creativity and energy.
Best for: Daytime use and creative focus.
Popular examples:
🌈 Hybrid Cannabis Seeds Strains.
Hybrids combine both indica and sativa genetics, offering a balance of body relaxation and mental stimulation.
Best for: All-round effects and adaptability.
Popular examples:
Girl Scout Cookies Cannabis Seeds.
3. How to Choose Seeds Based on Your Growing Space
Not all seeds are suited to all spaces. The key is matching your strain to your environment.
If you’re growing indoors, you control light, temperature, and humidity. You can grow almost any strain, but compact plants like indicas and auto flowers are easier to manage.
Recommended strains:
Bruce Banner Feminised Cannabis Seeds.
Cheese Auto flower Cannabis Seeds.
Outdoor grows depend on the UK climate, which means choosing hardy, fast-flowering strains. Auto flowers and indicas usually perform best in unpredictable weather.
Recommended strains:
Northern Lights Auto Cannabis Seeds,
Gorilla Glue Auto Cannabis Seeds.
🪴 Balcony or Small Space Grows
Short, compact strains are key for stealth and discretion. Auto flowers are ideal here.
Recommended strains:
Lemon Haze Auto Cannabis Seeds.
4. Matching Seeds to Your Experience Level
Every grower is different, and your choice of seeds should match your skill level.
Look for auto flowers or easy-to-grow feminised strains. They’re forgiving and resilient.
Best beginner strains:
Girl Scout Cookies Auto Cannabis Seeds.
You can experiment with photoperiod strains and training methods like topping or LST (low-stress training).
Best mid-level strains:
Cheese Feminised Cannabis Seeds,
Advanced growers can explore rare genetics, regular seeds, and high-yielding hybrids.
Best advanced strains:
Bruce Banner #3 Cannabis Seeds.
5. Understanding THC, CBD, and CBG Levels.
Choosing seeds isn’t just about flavour — it’s about cannabinoid content.
Responsible for the classic psychoactive effects. High-THC strains are powerful and long-lasting.
High-THC examples:
- Bruce Banner Cannabis Seeds (25%+)
- Gorilla Glue Cannabis Seeds (26%)
- Runtz Cannabis Seeds (24%)
Non-psychoactive and known for its calming effects.
High-CBD examples:
Sweet Nurse Auto CBD Cannabis Seeds.
Amnesia Pure CBD Cannabis Seeds.
A minor cannabinoid gaining attention for focus and clarity.
High-CBG examples:
CBD + CBG Relief strains
6. Choosing Seeds by Yield Size
Growers often select seeds based on yield potential — but yield depends on light, nutrients, and care.
🌾 Small Yields (Fast and Stealthy)
Auto flowers like Zkittlez Auto or Lemon Auto
Great for beginners and quick harvests
🌳 Medium Yields (Balanced Performance)
Cheese or Girl Scout Cookies Cannabis Seeds.
Perfect for small tents or gardens

Tips for storage:
- Keep seeds in a dark, cool, and dry place
