Best Autoflower Strains for Outdoor Growing🌱☀️Updated 21 days ago
Autoflowers are a great option for outdoor growers who want a faster grow, manageable plant size, and a simpler schedule.
Unlike photoperiod plants, autoflowers begin flowering based mainly on age rather than waiting for shorter daylight hours. That makes them especially handy for patios, balconies, smaller gardens, and areas with shorter growing seasons.
What Makes a Good Outdoor Autoflower?
When choosing an autoflower for outside, it helps to look for:
🌿 Compact or manageable growth
☀️ Good performance in your local climate
💨 Some tolerance to changing outdoor conditions
🪴 Suitability for container growing
⏱️ A relatively quick seed-to-harvest cycle
🐛 Good overall resilience
Keep in mind that the final size and finish time can still vary depending on the individual plant, sunlight, temperature, pot size, watering, and other growing conditions.
Good Autoflower Choices for Outdoor Growing
Northern Lights Autoflower
A longtime favorite and a nice option for newer growers.
Northern Lights Auto is commonly chosen for its manageable growth and hardiness, making it a good candidate for outdoor containers and patios.
It can also be worth considering if discretion is important, since its aroma may be more manageable than some especially pungent varieties.
That said, no cannabis plant can be guaranteed odor-free. 🌿👃
Blueberry Autoflower 🫐
Blueberry Auto is another beginner-friendly option that tends to stay fairly manageable in size.
It works well in containers and can be grown outdoors, making it a good choice when you don't have room for a huge plant.
Just remember that Blueberry is known for its aroma, so it wouldn't be our first choice if keeping smells to a minimum is your biggest concern.
Zkittlez Autoflower 🍬
Zkittlez Auto can be a good option for growers who want a manageable autoflower with colorful, aromatic flowers.
It adapts well to outdoor growing, but its aroma can become quite noticeable during flowering.
Bruce Banner Autoflower
Bruce Banner Auto can handle outdoor growing well and offers the convenience of an autoflowering plant without requiring a seasonal light change.
It can become fairly vigorous, though, so growers with very limited patio space may prefer a naturally smaller option.
Amnesia Haze Autoflower
If you prefer a more sativa-leaning plant, Amnesia Haze Auto offers a quicker alternative to traditional photoperiod Haze varieties.
Give it plenty of sunlight and enough room to develop, as it may stretch more than some compact indica-leaning autos.
What’s Best for a Small Patio? 🪴
If you're a beginner and want something easy to manage without taking over the patio, start by looking at naturally compact autoflowers.
Northern Lights Auto is a good place to start because it combines:
Beginner-friendly growth
A manageable size
Container-friendly growing
A relatively discreet structure
Generally less overpowering aroma than some of the louder varieties
A 3- to 5-gallon fabric pot is a good size for many patio autoflowers.
Just remember: smaller pot does not always mean tiny plant, and every plant can grow a little differently.
Will My Neighbors Smell It? 👃
This is one of the biggest questions we get from patio growers.
Unfortunately, there is no completely odorless cannabis strain.
Even varieties described as mild or low-odor can become much stronger during flowering, and outdoor scents can travel depending on wind, temperature, and how close neighboring homes are.
If discretion is important, avoid assuming that a compact plant will also have a weak smell — plant size and aroma aren't necessarily connected.
You may also want to avoid varieties known for especially strong Skunk, Diesel, or very pungent terpene profiles if smell is your main concern.
Tips for Growing Autoflowers Outdoors 🌞
Give them as much direct sunlight as possible.
Start them when temperatures are reliably warm.
Use a light, well-draining growing medium.
Consider planting directly into the final container to reduce transplant stress.
Don't overfeed young autoflowers.
Protect plants from severe rain, wind, and extreme temperatures.
Check regularly for pests and signs of mold.
Remember that fabric pots may dry faster outside, especially in hot or windy weather.
How Long Do Outdoor Autoflowers Take?
Autoflowers are generally quicker than photoperiod plants, but don't treat the number on the strain page like an exact deadline. ⏱️
Some may be ready in around 10 weeks, while others can take 12 weeks, 14 weeks, or longer depending on the strain and growing conditions.
Let the plant's maturity guide harvest rather than relying only on the calendar.
The Bottom Line 🌿
For beginners, compact autoflowers are usually the easiest place to start.
If keeping the plant manageable and reducing noticeable odor are priorities, Northern Lights Auto is worth considering — but no outdoor cannabis plant can be guaranteed to stay small or completely scent-free.
