The Best Outdoor Strains for 2020

This post is all about the best cannabis strains for outdoors; it’s a selection of strains that we’ve tried and tested outdoors so that you can narrow down your search for the perfect plant without getting a random strain that might not be best for outdoor settings. Outdoor season is almost here, and it’s time to get your seeds ready! Growing cannabis outdoors is a long, tiring process at times, taking from 4 to 8 months to finish maturing depending on the chosen strain; that’s why you should always plan ahead of time and know exactly what you’re going to be growing.

We’re going to give a brief overview of some of our tried and tested favorite outdoor cannabis strains so that you don’t blindly go into growing a random strain outdoors. There are literally thousands upon thousands of different strains on the market, all of which have various different characteristics – some are resistant to excess humidity, heat, insects and many other issues, some can be harvested earlier than others, some do better with stress than others… the idea here is to pick one that has the best characteristics for a successful outdoor cannabis plant.

The Best Outdoor Strains | Indicas

Caramel 100% Feminized

The first of our favorite outdoor indicas is over 80% indica and is perfect for outdoor growing. This strain is one of our 100% fem bulk strains. It won third place in the indica category in the Farallones Cup in Cali, Colombia – Caramel 100% Feminized.

Caramel is a 90% indica strain that stands out with its high quality yields marked by an intense, pungent aroma. This strain is a great alternative for those looking to grow outdoors thanks to its early harvest; it should be ready to harvest towards the end of September, with a strong, sturdy structure and incredibly compact flowers which allow for maximum airflow regardless of how compact they are, which allows them to stay dry in humid conditions.

Barney’s Farm Peyote Cookies

This strain belongs to the well-known Barney’s Farm seed bank, which is one of the best seed banks in Europe thanks to the high quality of its strains and their genetic make-up; Barney’s farm is always trying to create incredibly high quality strains.

Peyote Cookies is an indica-dominant plant, which is almost entirely indica, and it adapts well to pretty much any environment, making it easily one of their sturdiest strains. This is thanks to its genetic make-up, which allow it to grow super strong and compact, easily capable of dealing with rain and strong winds. Its buds are similar to those of Caramel, so they can easily stay dry in humid conditions, within reason.

The Best Outdoor Strains | Sativas

Amnesia 100% Feminized

Haze strains are known for being highly resistant to humid environments thanks to its open flower structure. In this case, Amnesia 100% Fem is a great choice as a sativa strain to be grown in rainy, high humidity levels, even though it’s ready to harvest in October outdoors.

Amnesia 100% Feminized is an 80% sativa strain that has been crossed with an Afghan in order to give it a slightly faster bloom period. This plant grows into an open structure easily, growing over 2.5m without needing much care at all. Due to being a sativa-dominant strain, its structure is a bit weaker than indicas, although this allows for more flexibility; its branches should be able to easily deal with issues such as rain and wind, however we recommend training them in order to be safe. This strains’ genes allow for plenty of incredibly aromatic plants outdoors.

Gorilla Girl® by Sweet Seeds®

Ever since Sweet Seeds released this beauty a few years ago, it’s turned into one of the favorite strains of outdoor growers around the world thanks to the amazing results that it produces. The reasoning behind this is that Gorilla Girl comes from a combination between two of the best US strains of the last decade, and possibly in all of cannabis history; one of them is Gorilla Glue and the other is a Girl Scout Cookies phenotype called Thin Mint – neither of these strains need an introduction, as they are two of the most well-known strains of cannabis in the world.

If you decide to try this strain in your outdoor grow, you’ll find that it’s a sativa-dominant plant that grows quite strong, producing an open structure and strong branches that can easily deal with bad weather and the weight of its hefty buds. When grown at the start of the season and in the ground it can easily grow up to 2.5m tall, producing almost 1kg per plant. It should be ready to harvest towards the start of October, although it should be fine when it comes to humidity as it’s naturally resistant to humidity and rot. However you’ll need to take care that caterpillars don’t get near your plants’ juice buds.

The Best Outdoor Strains | Hybrids

Sensi Seeds Jack Herer

Just like Durban and Amnesia, Jack Herer is another classic strain that many consider to be one of the best strains of all times. It’s a slightly delicate plant that needs a little extra care in order to produce some of the best buds you’ve ever seen.

Jack Herer is a 50/50 hybrid strain that tends to grow more like a sativa plant; its indica side helps for strong growth and allows it to deal with issues such as dry climates or low quality substrate. This strain is great for outdoors, although you’ll need to give it a helping hand by training its branches; it does well with issues such as heat and cold, as well as rainy climates. The only inconvenience regarding this strain is its long flowering period, taking until mid-October to harvest outdoors. The wait is well worth its delicious flowers.

Critical 100% Feminized

Critical strains have become a world-wide sensation ever since they started being grown in Spain, and there’s good reason for it; these plants are complete in every sense of the world, dealing incredibly well with many issues, although it is slightly susceptible to fungi infestations due to its massive, compact buds. Compared to other strains of similar stature, this one holds up the best when it comes to stress.

Critical 100% feminized is a 50/50 hybrid strain that grows almost as strong and steady as a sativa plant, although once it begins to bloom you’ll easily notice its indica heritage. It can adapt to pretty much any environment and easily deal with arid, cold, rainy and mild climates – it’s a great choice for guerrilla growers, although its aroma can be a bit scandalous at times. This strain comes from Skunk and Afghani plants, hence its genetic sturdiness and strength.

The Best Outdoor Autoflowering Strains

Auto Gelatto 100% Fem

Autoflowering strains are a great choice for those looking to grow cannabis in practically place in the world; it may take a bit of extra care at the start to get it going, but this strain will shoot up once it really gets a hang of it. The interesting thing about this strain is its short life cycle; there’s hardly any time for insects or fungi to even think about infesting it, although under extreme conditions it may happen. Auto Gelatto 100% Fem is a great choice for any grower, alongside the rest of out Growbarato.net bulk strains.

We’ve included this particular strain in this list, as it’s known for growing incredibly compact buds with plenty of distance in between to allow for airflow and humidity dissipation. It’s resistant to drought and excess heat too, which may end up causing it to grow less but it will also produce more resin. This strain is one of the best outdoor cannabis strains thanks to the amazing results that it provides without much effort at all.

Cream Mandarine XL Auto by Sweet Seeds

Autoflowering strains that produce large yields are popular right now, and this is definitely one of the best strains of the last few years; Cream Mandarine XL Auto. This strain comes from a cross between a Cream Mandarine Auto and a select clone of Super Tai’98, which makes for a plant that is incredibly strong and can grow up to 1.5m tall, impressive for an autoflowering plant. You can harvest between 50 and 300g per plant, harvesting after a total of 65 days from start to finish.

When grown outdoors, whether in a flowerpot or in the ground, this strain is an absolute monster in both height and width – keep this in mind when spacing them out, as they may end up shading eachother. On the other hand, this extreme growth allows you to prune and train it to fit your needs and to make sure that it can deal with strong winds while also increasing the size of its buds. This strain is generally quite resistant to insect infestations and humidity-induced fungi, so it’s great for both dry and humid climates; if you’re a beginner and not sure where to start, this autoflowering strain is a great idea.

The Best Outdoor Strains | Growing Recommendations:

Hopefully, after this brief review of some of the best outdoor indica, sativa and hybrid strains, you’ll have made your mind about about what strain you want to grow this year. Keep in mind that growing cannabis outdoors requires work; none of these plants will grow successfully if simply left to their own devices from day one. We recommend regular feeding schedules, as well as organically-sourced preventive products in order to keep them insect and fungi-free; try and get products specifically for typical cannabis infestations such as spider mites, caterpillars, fusarium fungi and others.

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 ruderalisAutoflowering 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.

Kyle’s Skywalker OG by Homegrown Cannabis Co. and Skywalker Haze by Dutch Passion

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 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.
