Growing your own cannabis under the open sky is one of the most rewarding experiences a cannabis lover can have. Whether you’re an aspiring grower or a seasoned enthusiast, learning how to grow a weed plant outside gives you the power to cultivate premium, flavorful buds straight from nature — no fancy indoor lights or equipment required.
Outdoor growing lets your plants bask in the natural sunlight, breathe fresh air, and develop robust terpene profiles that rival even the best indoor-grown strains. In this comprehensive guide, we’ll walk you through how to grow a weed plant outside, how to grow dense cannabis buds, and how long it takes to see your harvest sparkle with trichomes.

🌱 Understanding Outdoor Cannabis Growing
Before you dig in, it’s essential to understand what makes outdoor cannabis cultivation unique.
When you grow indoors, you control every variable — light, humidity, and nutrients. But when you grow outdoors, you’re working with nature’s elements: sunlight, rain, wind, and soil. While it’s less predictable, the rewards are immense — larger yields, lower costs, and richer flavor profiles.
Outdoor cannabis grows can produce massive plants, often towering over six feet tall, with heavy, resin-coated buds.
☀️ Why Grow Cannabis Outdoors?
There are many reasons growers love the great outdoors:
🌿 1. Natural Sunlight = Better Terpenes
Sunlight provides a full light spectrum that artificial lights can’t perfectly replicate. This helps the plant produce stronger flavors and aromas, making your buds smell and taste amazing.
💰 2. Cost-Effective
No need for lights, fans, or dehumidifiers — the sun and wind are free.
🌎 3. Eco-Friendly Growing
Growing cannabis outdoors reduces energy consumption and carbon footprint.
🌼 4. Big Yields
Outdoor plants have unlimited space for their roots, leading to bigger plants and higher yields.
😌 5. Therapeutic Experience
Watching your plant thrive in nature connects you with the process — a mindful, peaceful way to grow medicine or recreation.
🪴 Step-by-Step: How to Grow a Weed Plant Outside
Let’s dive into the essentials of growing cannabis under the open sky.
🌾 Step 1: Choose the Right Location
The success of your outdoor grow begins with location. Cannabis loves:
- At least 6–8 hours of direct sunlight daily
- Well-draining soil
- Protection from strong winds and pests
- A discreet space if privacy is needed
If possible, choose a south-facing slope for maximum sun exposure.
🌱 Step 2: Pick the Perfect Strain
Not all cannabis strains thrive outdoors. Some prefer warm climates, others need cooler nights.
Ideal outdoor strains include:
- 🌸 Blue Dream – Easy to grow, large yields, fruity aroma
- 🍋 Lemon Haze – Resistant to mold, strong citrus flavor
- 🌿 Northern Lights – Compact and resilient
- 🍇 Gorilla Glue #4 – Hardy hybrid with high THC
For those growing in humid areas, choose mold-resistant strains. In hot, dry zones, pick heat-tolerant hybrids.
🌍 Step 3: Prepare the Soil
Healthy soil = healthy plants.
Mix organic compost, worm castings, and perlite for drainage. The ideal soil pH is between 6.0 and 7.0.
Rich, loamy soil with natural microbes helps your plant absorb nutrients more effectively.
💧 Step 4: Watering Wisely
Watering depends on your climate, but a general rule is:
- Young plants: Every 2–3 days
- Mature plants: Deep watering once a week
Always water early in the morning or evening to prevent evaporation.
🌡️ Step 5: Nutrients and Feeding
Feed your plants with:
- Nitrogen (N) during vegetative growth
- Phosphorus (P) and Potassium (K) during flowering
Avoid overfeeding. Watch for signs like leaf burn or yellowing tips — less is often more.
For organic growth, use:
- Bat guano
- Seaweed extract
- Fish emulsion
- Compost tea
🌿 Step 6: Training and Pruning
Training helps maximize sunlight exposure and airflow.
Try:
- Topping: Cut the main stem to encourage multiple colas.
- LST (Low-Stress Training): Gently bend and tie branches to spread out growth.
- Defoliation: Remove excess fan leaves to improve airflow and bud density.
🌺 Step 7: Flowering Stage
After about 8–10 weeks of vegetative growth, your plant will start to flower as daylight hours shorten.
You’ll notice white pistils forming — these are the early signs of buds!
Feed more phosphorus and potassium, reduce nitrogen, and keep a close eye on weather patterns.
🕰️ How Long Does It Take to Grow Cannabis Outside?
One of the most common questions growers ask is: How long does it take to grow a weed plant outside?
Here’s a general timeline:
| Stage | Duration | Description |
|---|---|---|
| Germination | 1–2 weeks | Seeds sprout into seedlings |
| Vegetative | 6–10 weeks | Plants grow leaves and stems |
| Flowering | 8–12 weeks | Buds form and mature |
| Harvest | Late September–October | Time to trim and dry your buds |
⏳ Total Time: Around 4–6 months from seed to harvest, depending on climate and strain.
💎 How to Grow Dense Cannabis Buds Outside
Want your outdoor cannabis to have thick, frosty, and dense buds instead of airy flowers? Follow these pro tips:
☀️ 1. Maximize Sunlight
Place your plants where they’ll receive full, uninterrupted sunlight daily. Light equals energy — and energy builds dense buds.
💨 2. Improve Airflow
Use strategic pruning and spacing to reduce humidity and prevent mold, which can cause airy buds.
🌿 3. Feed Correctly
Increase phosphorus and potassium during bloom — these nutrients drive bud formation and density.
❄️ 4. Watch the Temperature
Maintain 70–85°F (21–29°C) during the day and 55–65°F (13–18°C) at night for optimal bud development.
🧬 5. Choose Dense-Budding Strains
Some genetics naturally produce heavier buds, such as GMO Cookies, OG Kush, and Gelato #41.
🌈 Flavor Profiles from Outdoor Grown Cannabis
One of the most exciting parts of outdoor growing is the flavor and aroma of your final product. The open air and natural light boost terpene production, resulting in bolder, more complex profiles.
Here’s what you can expect from various outdoor-grown strains:
| Strain | Flavor Profile | Effect |
|---|---|---|
| Pineapple Express | Sweet tropical fruit | Uplifting and creative |
| OG Kush | Earthy, woody, gas | Relaxing and euphoric |
| Zkittlez | Candy, citrus, berry | Happy, stress-relieving |
| Gelato 33 | Creamy, dessert-like | Balanced and calming |
| Sour Diesel | Diesel, citrus | Energetic and focused |
Outdoor growing often enhances earthy and piney terpenes, giving your cannabis a more natural, rich taste that’s impossible to fake indoors.
🌦️ Common Challenges When Growing Weed Outside
While outdoor growing is rewarding, it comes with challenges:
- Pests – Use neem oil, ladybugs, or companion plants like basil to keep bugs away.
- Mold and Mildew – Ensure good airflow and avoid watering late in the day.
- Weather Extremes – Cover plants with a greenhouse tarp or shade cloth during storms or heat waves.
- Theft or Animals – Use fencing or camouflage for protection.
Patience and vigilance are key — nature rewards those who work with it, not against it.
🌿 The Harvest and Curing Process
When your buds are sticky, aromatic, and full of milky trichomes, it’s time to harvest.
- Cut your plants at the base.
- Trim excess leaves.
- Hang dry in a cool, dark place for 7–10 days.
- Cure in jars for at least 2–4 weeks to enhance flavor and smoothness.
Curing allows cannabinoids and terpenes to fully mature, transforming your buds into smooth, flavorful smoke or vapor.
