Given a choice between growing outdoors or indoors, most growers would grow their cannabis plants outdoors. It’s an absolute joy to grow marijuana outdoors and observe their beauty, aroma, and promises of pleasure that are soon to follow after they are harvested. Cannabis is now legal in many locations and many countries are now catching up. If you’re lucky enough to be able to grow outside, it’s good to understand the advantages. Artificial lights are almost as good as sunlight but nothing beats nature and its efficacy so these are the best auto seeds for outdoor growers.

So make sure to take a look at our top 5 autoflowering cannabis strains for outdoor growers that will give you the upper hand against less-than-ideal climates!Remember that these strains can be grown indoors as well, but they are adept at producing high yields when grown outdoors.

1. What are the advantages of growing cannabis outdoors?

Growing cannabis outdoors is the easiest and cheapest way to grow cannabis, this is because most of the things needed are already provided by nature, it’s possible that in some cases you will have to buy or make your own nutrients such as compost, KNF, or buy fertilizers at your local grow shop but, in general, you only need a piece of land, sunlight, and water.

When growing outdoors, you won’t need a high-intensity light bulb or an expensive LED while still allowing your plant to grow to its full potential, producing lots and lots of trichome and terpenes due to receiving sunlight which emits the full spectrum.

There are several advantages when growing outdoors, the main one being that you don't need electricity!

Also, growing outdoors is environmentally friendly and sustainable, if you grow your cannabis with a more natural approach. If you plan your grow cycle before starting it, you won’t need to use electricity for fans or any other equipment, maybe you don’t even need a greenhouse, it’s just a matter of germinating, planting, and then letting your plants do their thing.  Obviously, you will have to water and feed them but that’s it, unlike when growing indoors where you’ll have to check a thermometer and a hygrometer to make sure the conditions are on point, adjust the light intensity, distance, fan speed, etc...basically, mimic the outdoors environment inside of your grow tent or grow room.

  • Natural Sunlight

As I mentioned already, sunlight is unbeatable. Photoperiod strains need at least 18 hours of sunlight, and many countries don’t receive sunlight for that long. So, simply shift to autoflowers. Autoflowers will also do well if they get 18 hours, but they won’t complain too much if they get only 12 hours, which is the case in many countries.

Autoflowers will thrive in natural sunlight because they get everything they need. From vital nutrients present in the soil to light containing all the colors necessary for it to grow – you can expect a bumper crop.

  • Huge Yields

Have you ever tried growing outside? Or have you seen pictures of growers flaunting their plants growing outdoors? No? I suggest you take a look. Cannabis plants are naturally meant to be grown outdoors. Although they won’t be spoon-fed like plants growing indoors, they turn out to be monsters if you grow them only twice a year.

And that’s another thing – many people complain that they get only two seasons to grow outdoors. Say, what? If you compare the yields, growing outdoors will produce at least twice the yields.

  • No maintenance

Plants growing outdoors quickly adjust to their conditions. You don’t need to monitor them constantly. You simply sow the seeds and let them do their thing. If the soil isn’t very fertile, you’ll need to provide fertilizers, but compared to the maintenance for plants growing indoors, this is a walk in the park.

  • Less effort

Indoor plants need a lot of work. From getting the temperature right to adjusting humidity, you need to put in a lot of efforts. Then there’s pH and whatnot. If you’re into hydroponics, your efforts increase and you have to monitor the water too.

But when the plants are outside, you don’t have to worry about pH at all. The plants grow naturally, just like other plants, and adjust to their environment. It’s called weed for a reason, after all.

  • Save lots of money

It takes a good amount of money to grow marijuana indoors. The electricity bills for the lights, the grow tents, or materials to build your own grow room – they cost quite a bit. Some people love growing indoors because it gives more control over the plants.

Growing outdoors saves you a lot of money but the quality and quantity will be affected by the environment.

However, it can cost you a serious amount if you don’t plan well. Although you need to spend more only the first time while setting things up, try your best to grow outdoors if you have the option because you won’t be spending anything at all. So, let’s take a look at the top 5 autoflowers that can be grown outdoors:

2. Gorilla Zkittlez Auto

Gorilla Zkittlez Auto is an outstanding award-winning autoflowering strain winner of Dabadoo Brasil 2022 and the American Autoflower Cup 2022, offering growers top-quality harvests in as little as 9 weeks from seed to harvest.

It’s a very stable strain that continues to grow in the harshest of conditions and with minimal maintenance, just like its ancestor Ruderalis.

Amnesia Zkittlez Auto plants have the tendency to branch out. So, you can expect one main stem and multiple side branches that stands like a tower packed with flowers that smell and taste delicious. She will grow too big, and her flowering period is complete within just 9-10 weeks, but you’ll keep coming back to this strain simply because it’s so easy on the eyes and easy to grow as well.

4. Gorilla Cookies Auto

Many growers in Europe have reported that the Stardawg is perfect for their style of growing which requires very little to no maintenance. When grown indoors, the plant grows up to 120cm in height, but you can expect a big stretch when it’s outside. She loves flaunting her buds and you’ll wonder whether you planted an autoflowering strain or a tree!

6. Californian Snow Auto

Growing the California Snow Auto outdoors is like growing an apple tree! For one, she tastes like apples, and for two, she grows almost as huge as a tree. She’s named “Snow” because the trichome production increases to such an extent that it looks like you have a tree with a generous amount of snow!

With white resin oozing out from every corner of the plant, the California Snow Auto is one of a kind. She’s a mixed hybrid with traits of both Indica and Sativa. The effects of this strain won’t be as prolonged as the others, but it’s all worth it, especially when you feel the rush hit you. This strain works well for both residential and commercial growers since she produces up to 250 grams of pure bud covered with crystals from one single plant. She’s not ideal for growers with small spaces, so make sure you give her loads of room.



Perfect for those residing in colder climates, the California Snow Auto will finish her flowering cycle in just 9-10 weeks. Rich flavors of citrus and lime will make you grow her again and again until you’re satisfied. Fastbuds autoflowering seeds can be sown both indoors and outdoors, but if you have an option to grow outdoors, why not go for it? Apart from the advantages mentioned above, you’ll also have quality buds that’ll make you a star among your friends. The ability to grow outdoors is a gift, so don’t let it go to waste and use your skills to produce the best buds you’ve ever laid your eyes on!

8. In conclusion

There are a lot of strains that can grow really well outdoors and, if growing autoflowers, there's no need to wait for the outdoor season, you can grow all year long. Even though there are certain cannabis strains that can indeed give you an upper hand when growing outdoors, autoflowers contain Ruderalis genetics which makes them more sturdy and resilient to harsher climates. This doesn’t mean autoflowers will grow in freezing conditions but as long as the temperatures range within 15 - 25 °C and the humidity levels range within 40 - 70% you will be able to grow and harvest pretty good bud with basic maintenance. Obviously, in order to guarantee the quality you will have to keep your plants well-fed and happy, and make sure you provide the right conditions for the drying and curing process just like with any other type of cannabis genetics.

But other than that, autoflowers are an excellent choice for beginners, cultivators dealing with less-than-ideal growing conditions and growers looking for a quick turn-around in as little as 8 weeks without sacrificing the quality or quantity of the harvest.
