Top 10 Autoflowering Strains To Grow Outdoors (2024)

 

One of the best traits about autoflowering Cannabis, is how these tough resilient plants can adapt to all climates allowing a grower to harvest top grade buds all year round. Growing autoflowering strains outdoors can be tricky due to weather conditions or not-so-good genetics. To avoid a bad experience you need to choose resilient and high yielding autoflowering strains. This will allow you to successfully harvest all year long without too much worry even in cold or hot climates. Below are our top ten strains you should consider growing in 2024, so you can keep those curing jars full to the brim.

1. Growing Autoflowers Outdoors

Autoflowering strains have a mix of different cannabis species including Ruderalis, this makes them extremely resilient for growing outdoors, being able to withstand not only hotter and colder climates but also bugs and mold. These characteristics along with the autoflowering trait make it possible for growers to cultivate autos outdoors and harvest all year long without having to worry about the amount of light they get, although the yields may vary if your plant gets more (or less) sun, you will be pleased with the results. The amount of light you get in each season may vary depending on where you live, but you can use this table as a general guideline:

 

Duration Dec 1-Feb 28 Mar 1-May 31 Jun 1-Aug 31 Sep 4-Nov 30
Season Summer Fall Winter Spring
Average Hours of Light 14hrs 11hrs 10hrs 12hrs

Approximate hour of sunlight per season in the northern hemisphere1.
 

You don't actually need to make a table, you can obviously check on the internet or download an app to have an idea of the expected weather throughout your growing cycle, this makes it possible to plan ahead and prepare for eventual storms or other things. For example, if you're expecting rain or strong windstorms you can improvise a homemade greenhouse to protect your plants.

13. In Conclusion

There are a lot of autoflowering varieties that can be grown extremely well outdoors, autos are super resilient to cold, hot climates and bugs and mold, the strains mentioned above are our top 10 that will surely leave you pleased and amazed at the quality and amount of buds. Just remember that, as said in the introduction, it's highly recommended to plan ahead so your plants get the most amount of direct sunlight possible. You can have a very good harvest all year long but planning ahead so your plants get more sunlight will result in bigger and denser buds, with an increased trichome production; The trichomes are where the terpenes and cannabinoids are produced and store so you will not only get better yields but you will also get a more potent, tastier and better smelling final product without doing anything extra, just planning so it's definitely recommended.

Always make sure to check online for the weather during the next couple of months, this will allow you to know what to expect and what to prepare for; Maybe you need a small greenhouse or maybe you need a plastic sheet to cover your plants when it rains, anything goes to protect your precious babies. Knowing the expected weather will not only give you an advantage but also avoid future problems so make sure you check everything before starting your next cycle outdoors and get growing!
