Growing Cannabis Outdoors with Cannabis Seeds
Growing cannabis outdoors can be a rewarding and cost-effective way to cultivate your own high-quality buds. However, success depends on understanding the needs of your plants, choosing the right seeds, and selecting the best location. Whether you’re using feminized or autoflowering seeds, each type has its own advantages. In this guide, we’ll break down everything you need to know about growing cannabis outdoors, from picking the perfect spot to harvesting your plants.
Growing cannabis outdoors – Choosing the Best Location for Your Cannabis Plants
One of the most critical factors in outdoor cannabis cultivation is location. Cannabis thrives in sunlight, so it’s essential to pick a spot that gets plenty of direct sun exposure. Ideally, your plants should receive at least 8–9 hours of sunlight per day for optimal growth.
However, some growers have found that partial shade in the early evening can be beneficial. This slight decrease in direct sunlight can sometimes trigger earlier flowering, leading to an earlier harvest and reducing the risk of bud rot, especially in humid climates. A location that receives sunlight from around 9 AM to 6 PM is a great choice.

Growing Cannabis Outdoors – Other Factors to Consider When Choosing a Grow Spot:
- Shelter from strong winds – Wind can damage delicate branches and cause water loss through excessive evaporation.
- Protection from heavy rainfall – While cannabis needs water, excessive rain can lead to mold and mildew.
- Good drainage – Avoid areas where water pools after rain, as this can cause root rot.
- Privacy and security – If growing in a non-legal area, a discreet location will help keep your plants safe.
Feminized vs. Autoflowering Seeds: Which One to Choose?
Once you’ve found the perfect location, it’s time to choose your seeds. The two main options are feminized seeds and autoflowering seeds, and each has its own advantages.
Growing cannabis outdoors with Feminized Seeds: Higher Yields and More Control
Feminized cannabis seeds are bred to produce only female plants, ensuring that every plant will grow buds. They rely on the natural photoperiod (changes in daylight hours) to begin flowering, meaning they typically start flowering in late summer when the days get shorter.
Advantages of Feminized Seeds:
- Higher yields – Since these plants grow larger, they tend to produce bigger harvests.
- Stronger genetics – Feminized plants often have more stable genetics and robust growth.
- Control over vegetative growth – Because they rely on daylight hours, growers can manipulate their growth phase by controlling light exposure.
Disadvantages of Feminized Seeds:
- Longer growing cycle – They take several months to mature, requiring patience.
- Risk of bud rot – If they aren’t harvested before rainy autumn weather, moisture can cause mold.
- Dependent on daylight changes – Flowering won’t start until the natural light cycle triggers it.

Growing cannabis outdoors with Autoflowering Seeds: Fast, Easy, and Resilient
Autoflowering seeds, on the other hand, flower automatically based on age rather than light cycles. This means they can be harvested much faster, often within 10–12 weeks from germination.
Advantages of Autoflowering Seeds:
- Faster harvests – You can harvest in as little as 12 weeks, making them ideal for multiple yearly grows.
- Less risk of mold and rot – Since they mature before autumn, there’s less exposure to bad weather.
- Compact size – Great for growers with limited space or those wanting a discreet grow.
- Hardy and resilient – Autoflowers are resistant to pests, mold, and fluctuating weather conditions.
Disadvantages of Autoflowering Seeds:
- Smaller yields – Since they grow quickly, they don’t get as large as feminized plants.
- Less control – Once they start flowering, you can’t manipulate their light exposure to control growth.
- Lower THC content (in some strains) – Some autoflowers may have slightly lower THC levels than their feminized counterparts.
Growing Cannabis Outdoors – When to Plant Cannabis Outdoors
The best time to plant depends on your location and climate. Cannabis plants need warm temperatures to grow properly, so timing is key.
- In the UK and Northern Europe, it’s best to start germination in late May or early June. This ensures that plants receive enough warmth and sunlight during their crucial early stages. Autoflowers planted at this time will be ready to harvest around August.
- In Southern Europe, where the climate is warmer, you can start planting as early as March. This allows for multiple harvests throughout the year, with some growers managing up to three crops annually using autoflowers.

Growing cannabis outdoors – Caring for Outdoor Cannabis Plants
Watering Your Plants
Cannabis plants need consistent watering, but overwatering can be a major problem. Check the top few inches of soil—if they feel dry, it’s time to water. If the soil is still damp, wait another day.
Nutrients and Soil
- Use rich, well-draining soil with organic matter.
- Feed with nitrogen-rich nutrients during the vegetative stage and phosphorus-heavy fertilizers during flowering.
- Consider natural fertilizers like worm castings or compost for a more organic approach.
Protecting Against Pests and Mold
- Use companion plants like basil, marigolds, or mint to deter pests.
- Apply neem oil or organic insecticidal soap if you notice pests like aphids or spider mites.
- Ensure good airflow around your plants to reduce the risk of mold and mildew.
Growing cannabis outdoors – Harvesting Your Outdoor Cannabis
Knowing when to harvest is crucial. Look for the following signs:
- Trichomes turning cloudy or amber – These tiny resin glands will change color when buds are mature.
- Pistils darkening – The white hairs on buds will turn orange or brown.
- Leaves yellowing – In the final weeks, leaves may naturally yellow as the plant directs energy to the buds.
Once ready, harvest by cutting the branches, trimming excess leaves, and drying them in a dark, ventilated space for about 7–10 days. After drying, cure the buds in airtight jars for at least two weeks for the best flavor and potency.

Final Thoughts about Growing Cannabis Outdoors
Growing cannabis outdoors with feminized or autoflowering seeds can be an incredibly fulfilling experience. Feminized seeds offer larger yields but take longer to mature, while autoflowers provide a fast, hassle-free harvest with multiple growing cycles per year. By choosing the right location, planting at the right time, and providing proper care, you can enjoy high-quality outdoor cannabis with minimal effort. Happy growing!
