Outdoor Cannabis Seeds for UK Climate: What to Grow and Why.

Growing cannabis outdoors in the UK can be incredibly rewarding – but success depends heavily on choosing the right outdoor cannabis seeds for UK climate conditions. With shorter summers, cooler temperatures, and higher humidity than many other regions, British growers need cannabis seeds that are resilient, fast-finishing, and reliable.

At Discount Cannabis Seeds, we focus on cannabis seeds that perform well in real UK outdoor environments. In this guide, we’ll explain what makes cannabis seeds suitable for outdoor growing in the UK, which types work best, and how to maximise your chances of a successful harvest.



Understanding the UK Outdoor Growing Climate.

The UK presents a unique set of challenges for outdoor cannabis cultivation:

  • Mild but unpredictable summers
  • High humidity and frequent rainfall
  • Shorter daylight hours compared to southern Europe
  • Increased risk of mould during flowering

Choosing outdoor cannabis seeds specifically suited to these conditions is essential for healthy plants and successful harvests.

What Makes Cannabis Seeds Suitable for UK Outdoor Growing.

When selecting outdoor cannabis seeds for UK climate conditions, look for the following traits:

✔ Short Flowering Time.

Cannabis seeds with shorter flowering periods are more likely to finish before autumn weather sets in.

✔ Mould and Pest Resistance.

UK humidity increases the risk of bud rot and mildew. Strong genetics help plants resist these issues.

✔ Hardy Growth Structure.

Sturdy plants cope better with wind, rain, and fluctuating temperatures.

✔ Moderate Plant Size.

Medium-sized plants are easier to manage and less affected by poor weather.

Best Types of Outdoor Cannabis Seeds for the UK.

🌱 Auto Flower Cannabis Seeds.

Auto flower cannabis seeds are one of the most popular choices for UK outdoor growers. Because they flower based on age rather than light cycle, they finish quickly and reliably.

Benefits include:

  • Fast life cycle (often 8–10 weeks)
  • Compact plant size
  • Ability to finish before autumn rain
  • Ideal for beginners

🌿 Feminised Cannabis Seeds.

Feminised cannabis seeds are another strong option, especially for growers who want larger plants and higher yields.

Why UK growers choose feminised cannabis seeds outdoors:

  • No male plants to remove
  • Higher usable harvest
  • Suitable for greenhouses and sheltered gardens

Fast-finishing feminised cannabis seeds are particularly effective in the UK.

🍃 Photoperiod Cannabis Seeds.

Photoperiod cannabis seeds can be grown outdoors in the UK, but they require careful strain selection. Early-flowering and mould-resistant varieties perform best.

Many UK growers choose photoperiod cannabis seeds for greenhouse grows, where flowering can be better protected from wet weather.

Best Outdoor Growing Locations in the UK.

To get the most from outdoor cannabis seeds:

  • Choose sunny, south-facing spots
  • Provide shelter from strong wind
  • Consider greenhouses or polytunnels
  • Avoid low-lying, damp areas
  • Good airflow is essential to reduce mould risk during flowering.

When to Plant Outdoor Cannabis Seeds in the UK.

Timing is crucial for outdoor success.

Auto flower cannabis seeds: Late April to early June

Feminised cannabis seeds: Late April to May

Photoperiod cannabis seeds: April (preferably started indoors)

Starting cannabis seeds indoors before moving them outside can give plants a strong early advantage.

Tips for Outdoor Cannabis Growing in the UK.

  • Use well-draining soil
  • Avoid overwatering
  • Space plants to improve airflow
  • Monitor closely during late flowering
