5 iconic cannabis strains that grow great outdoors
Growing weed outdoors isn’t as simple as throwing seeds in the ground and letting Mother Nature take care of the rest. Sure, these seeds could grow without TLC, but they probably won’t reward you with a ton of THC.
While planting weed outdoors isn’t as simple as plopping seeds in a patch of dirt, it’s getting easier for new cultivators to experiment with outdoor cultivation. Indeed, thanks to the popularity of day-neutral cannabis (often referred to as autoflowers) seeds, even novice gardeners can successfully grow legendary strains outdoors in only a few months.
Unlike traditional cannabis varieties that can generally only be grown outdoors as one crop per year as an annual plant, these flowers don’t depend on the sun to trigger their natural maturation, and thus allow you to grow outdoors any time of the year the weather permits. This autoflowering trait, which was first identified in wild Cannabis Ruderalis varieties found in Russia that produced very little usable flower, is now being bred into modern strains, giving growers the best of both worlds. 1
If you’re getting started growing cannabis outdoors, you must research the resiliency of your chosen strains. Some cannabis cultivars perform better in outdoor environments, while others have been bred for indoor growth. 2 Be sure to select seed distributors who provide information on the optimal environmental conditions to ensure the most suitable outdoor strain for your climate. Reviewing these factors should help you plant a successful outdoor “ganja garden.”
Growing weed outdoors: the crucial factors to consider
Since cannabis naturally evolved outdoors, it may seem strange that you can’t plant every strain outside your home. While it’s true cannabis is generally resilient enough to grow outdoors, some of the more modern varieties have bred specifically for growing indoors and could struggle with elements, pests, or both.
For instance, many of today’s specialty hybrids were made in controlled indoor environments. When you’re starting out growing weed outdoors, you should try to look into a strain’s history to ensure it isn’t overly reliant on the precision of an indoor grow tent.
Ideally, outdoor weed seeds should have a strong record of mold and pest resistance. These strains should also be able to handle slight temperature fluctuations with ease. Since you can’t control humidity and temperature outdoors, it always helps to plant robust varieties that won’t die off after a few unseasonably brisk nights.
Lastly, you have to consider your environment when choosing the best cannabis seeds to plant outdoors. Take a look at historical temperature, precipitation, and humidity data in your area. Be sure to compare these average ranges with the preferred climate for your favorite cannabis varieties, which should be provided by the breeder. After a bit of analysis, you should develop a short list of strains that would do well outside your home.
Most Durable Outdoor Cannabis Strains
Even though cannabis is an extremely durable plant that can grow in a number of different climates, there is no doubt that some cannabis strains or varieties are more well-adapted to growing outdoors than others. Here’s some advice on which strains are ideal for growing cannabis outdoors.
What to Look Out For In an Outdoor Variety or Strain of Cannabis
- Hybrid vigor – you will want a strain that is the offspring of two or more other strains, as hybrids are more likely to be resistant to mold, mildew, pests and other diseases.
- Cannabis ruderalis –Autoflowering varieties are tough, grow quite quickly and are very stable. They do not require a long vegetative period, and grow based on age rather than light cycles, due to their being from cold climates with much less sunlight. Autoflowering strains are ideal for guerilla growers.
- Feminized cannabis seeds – If you can’t find what you’re looking for with autoflowering varieties, then feminized seeds may be ideal, and can still save you some time making sure there aren’t any males in your crop. In the past, regular and autoflowering strains were usually a bit tougher and could take sudden shocks (e.g. sudden changes in lights or nutrients) a lot better, but this has changed somewhat.
- Tried and tested – Names like Skunk #1, Northern Lights and Holland’s Hope may not be as exciting these days, but they have stuck around because they’re reliable and can be grown over-and-over again without much fuss. Usually, a variety that has been used to cross and make other strains is a good candidate for an outdoor grow.
- Outdoor grow reports – There are plenty of forums where people share their expertise and experiences with growing a particular strain/variety/chemovar outdoors. Check them out, as they’ll give you tips on how best to grow a particular strain.

Gorilla Glue #4 Autoflower – Blimburn Seeds
Gorilla Glue is a modern classic, and is one of the most popular indica cannabis varietals on the market today. The autoflowering version is ideal for those seeking a type of cannabis with a relaxed, calming, sleepy effect that is potentially useful for treating anxiety, depression and arthritis. As this version is an autoflowering indica, it won’t grow very large, either – 90 cm. This is great for guerilla growers and those trying to keep discreet.

Skywalker OG is a cross of Mazar and Blueberry. It is a well-loved and potent indica that has been grown for many years, which has now been stabilized and been perfected for growing outdoors by Kyle Kushman. Skywalker OG is an excellent indica for insomnia and chronic pain.
Add some Amnesia Haze to the mix, and you now have a similarly potent, high-yielding sativa that is excellent for growing outdoors. Skywalker Haze is a hard-hitting, sativa dominant hybrid with a taste leaning to the citrus side of the spectrum, whilst still packing that legendary Mazar/Blueberry punch and fruity aftertaste.

Nikki and Swami’s Lemon OG Feminized
Swami and Nikki are some of California’s premier outdoor cannabis growers, so you can bet that most if not all of the cannabis varieties they’ve created are excellent for growing outdoors. Lemon OG feminized is a cross between Las Vegas Lemon Skunk and OG #18. Even though it grows like an indica, Lemon OG has sativa-like effects, elevating the mood and lending creative inspiration. This is short-lived, however, as it can lead to more drowsy, relaxing effects.

Steve’s Dream Queen Feminized
The list here was looking a little indica-heavy, so we thought to add an uplifting, energetic sativa to the mix – excellent for those with conditions like chronic fatigue syndrome, chronic pain, fibromyalgia, depression and stress. Steve’s Dream Queen is a THC- and CBD- packed beauty that doesn’t grow too tall, but still has a solid yield.

Mango Kush Feminized / CBD Mango Feminized
Mango Kush is a cross between Mango and Hindu Kush. As Kush plants naturally grow in dry, arid and mountainous areas, they are a hardy plant that can withstand harsh environments. Mango Kush is a calming and relaxing plant that packs a strong and weighty punch. It has analgesic effects, and is perfect for treating chronic pain.
CBD Mango is a cross between Mango and a high-CBD strain. It has CBD levels of up to 15%, and THC levels ranging from 15% to 24%. This means that CBD Mango has a THC:CBD ratio roughly between 1:1 and 2:1. It is an excellent choice for conditions that can cause muscle spasms (e.g. multiple sclerosis), inflammation and irritable bowel disorders (IBDs). Cultivation-wise, this strain is quite easy to manage. Moreover, Mango CBD boasts a prolific harvest of purple-hued buds that grow up to the size of a softball.
