Guidelines To Help You Choose Your Seeds

Are you new to the world of weed? Picking the right strain to grow can be daunting, especially with so much variety out there. In this article, we'll guide you through the sea of cannabis strains and help you pick out the ones that best suit your growing style and experience, as well as your smoking preferences. 

Making Sense of Cannabis Strains

There are thousands of cannabis strains available. Some of them make you feel relaxed, whereas others stimulate you. Many strains offer sweet tastes of fruit and candy, but an equally large share are more earthy and floral. Then there are those highly productive strains that peak at 3m tall, and those that are small enough to grow in a cupboard.

To make shopping for cannabis strains a simple task, you need to consider your desires, circumstances, and tastes. Below, we’ve highlighted the major factors you should consider before browsing cannabis seeds. Once you’ve selected your favourite traits, head to the bottom of the page to discover the easiest way to narrow down your search.

How to Choose Cannabis Seeds Based on Growing Conditions

Cannabis strains come in all shapes and sizes. From tall, stretchy sativas to compact, bushy indicas, hybrids, and autoflowers, there’s no shortage of variety when it comes to weed plants. When it's time to pick a strain for your next grow, it's always a good idea to consider your growing conditions (whether you'll grow indoors or outdoors), the local law (and how that might affect the way you grow), and yield quantity.

Below, you'll find curated selections of strains categorised by their genetics, height, flowering time, yield capacity, cannabinoid concentration, and pest resistance. Browse through the categories to find the strains most suited to your growing style, conditions, and preferences.

Top Sativas

Sativa strains originate from warm, tropical regions. They are ideal for growing outdoors where they can soak up the sun, heat, and humidity to maximise their height and yield potential. However, the catch is that sativas tend to take their time to flower (anywhere from 10–14 weeks or longer, depending on genetics), but the wait is definitely worth it. At harvest time, a strong sativa will reward you with long, resinous flowers boasting delicious aromas and uplifting, euphoric effects.

Below are our top 5 sativas. For more variety, check out this overview of other great sativa strains.

Top Indicas

Indicas are typically short, bushy, and relatively fast flowering, and thus are perfectly adapted to the cooler, harsher climates of the mountainous regions they originate from. This makes them ideal for indoor growers working with smaller spaces, or outdoor growers living in regions with more temperate climates and shorter summers. Come harvest time, a good indica will be laden with tight, dense flowers coated with resin, and will typically deliver more relaxing effects.

Top Small Plants — Ideal for Closet Grows, Small Tents, or Stealthy Outdoor Growing

When it comes to cannabis, size definitely matters. Larger cannabis plants naturally produce bigger yields, but they can be hard to grow in small spaces, and can very easily attract the attention of prying eyes outdoors. That's where smaller strains are perfect—they’re a breeze to grow in confined tents or closets, and they’ll go unnoticed in your outdoor garden. And they just might impress you with their yields, too!

Top Tall Plants for Huge Yields

If you’re lucky enough to have a large indoor tent or room to grow in, or an outdoor garden where privacy isn’t an issue, why not experiment with an XXL cannabis strain that promises bountiful yields? Besides leaving you with a ton of bud, growing large cannabis plants can be super exciting, as their sheer size can be breathtaking. Just remember that larger plants may require special maintenance, such as trimming/pruning, defoliation, or training.

Below is a list of our favourite extra-large, high-yielding cannabis strains. Also, be sure to read up on how to grow and maintain large cannabis plants in order to achieve the best results.

Top Fast-Flowering Strains

Fast-flowering strains let you get to harvest in express time. They are ideal for outdoor growers living in regions with short summers, or those in warm regions who want to achieve multiple harvests over one growing season. Indoors, fast-flowering strains can reduce the costs of running your grow tent or room while providing you with a consistent flow of weed.

Top High-Yielding Strains

Let's be honest; every grower loves a heavy harvest. But if you're particularly focused on getting the maximum return from your crop, it’s necessary to choose a strain that's been specifically bred to produce a lot of bud. Large yields are especially appealing to indoor growers who may want to see some "green return" after making a large upfront investment in grow gear. Note that high-yielding strains needn’t necessarily be very large or tall—many medium-sized strains can produce exceptional harvests too.

Below are our top 5 high-yielding cannabis strains. For more variety, check out some other highly productive strains.

Top Low-Smell Strains

While smokers and growers love the smell of ripe buds, their neighbours might not. Luckily, cannabis breeders have taken the time to create strains that produce minimal odour during the flowering phase. If you're growing weed outdoors on a terrace, in an apartment building, or anywhere else where unsupportive noses might get a whiff of your plants, investing in a low-odour strain can help to avoid drawing unwanted attention to your grow-op.

What follows are our 5 favourite low-odour cannabis strains. For more options, check out these other low-smell varieties.

Top High-THC Strains

Cannabis has come a long way since our ancestors first cultivated it thousands of years ago. Over the last few decades, for example, cannabis has been specifically bred to produce extra-high levels of THC, resulting in more potent and longer-lasting effects. If you love a deeply relaxing stone or a pseudo-psychedelic high, make sure to look for high-THC strains.

Below are our favourite high-THC cannabis strains. Check out a more elaborate list for even more options.

Top Low-THC Strains

High doses of THC aren't for everyone. In fact, many cannabis users prefer the more subtle effects of milder weed strains, especially if they're new to cannabis, haven't smoked in a long time, or choose to use it during the day. Medical cannabis patients may also prefer the effects of more balanced strains, particularly if addressing chronic symptoms on a daily basis. Our low-THC strains have been bred to produce minimal amounts of the psychotropic cannabinoid, without sacrificing aroma or flavour.

Below are our 5 favourite low-THC cannabis strains. See the full list here.

Top High-CBD Strains

The discovery of CBD and its myriad of potential benefits forever changed the way people view and use cannabis. Today, high-CBD cannabis strains are treasured both by recreational users and medical patients who don't enjoy the intoxicating effects of THC. Plus, thanks to the hard work of breeders, modern CBD strains are capable of producing the same delicious aromas and flavours normally associated with THC-rich cannabis varieties.

Top Resistant Strains 

A strain's ability to ward off pests and pathogens can be directly related to its genetics. If you're an outdoor grower or unable to create the perfect growing environment in a tent or room, investing in a highly resistant cannabis variety can make the difference between a great yield and a mediocre one. Resistant strains will typically perform well even in subpar conditions, and are particularly good at repelling pests/pathogens as well as dealing with stress. They're a great choice for inexperienced growers, as well as anyone working in less-than-ideal conditions.

Choosing Cannabis Seeds Based on Taste, Aroma, or Effects

How tall or fast a cannabis strain grows means nothing if you don't enjoy the flavour, aroma, or effects it produces. Hence, after considering your growing skill and style, we also recommend reviewing a strain's taste, smell, and effects to ensure you end up harvesting buds that you actually want to smoke. Luckily, thanks to the hard work of our breeders and our extensive catalogue of seeds, we guarantee you'll find an RQS strain that'll meet even your strictest criteria. 

Cannabis taste

Cannabis flowers are full of phytochemical complexity, and a specific set of molecules, known as terpenes, underpin the taste of each toke. These aromatic hydrocarbons are found all throughout nature, and are responsible for the tastes of citrus peels and the unique flavours of different herbs and spices.

Pay close attention to the terpene profile of each strain when shopping for seeds. If you like a peppery and savoury taste, scout out high levels of caryophyllene. Perhaps you prefer fresh, earthy notes? If so, look out for pinene and myrcene. Many smokers prefer fruity and sweet cannabis strains, which are loaded with terpenes such as linalool and limonene.

Keeping these terpenes in mind will give you a broad understanding of how a strain will taste. But, you’ll want to get more specific once you’ve narrowed down your search. Although most strains feature high levels of a particular terpene, they all feature a unique blend of dozens of these flavour molecules. Here’s an idea of the specific tastes available in each strain:

Fruit Spirit
Blueberry, fruit, earth
Bubblegum XL
Candy, sweetness, sugar
Green Gelato
Mint, vanilla, citrus

Chocolate Haze
Chocolate, sugar, earth

Cannabis aroma

Aroma forms the second crucial pillar of cannabis strain preference. Terpenes also underpin how a cultivar smells, but they smell and taste slightly different. In other words, the pungent smell of fresh or dried cannabis flowers doesn’t exactly determine how they taste.

Why? Well, terpenes are volatile molecules. Following exposure to a flame, they change in structure. Plus, they light up nerves in the tongue and nose differently.

It’s important to love the smell of the weed you grow. Not only because you and your friends will be blazing it for the next month, but because your grow tent and garden will quickly fill up with smelly terpenes during the flowering stage.

Thankfully, modern growers have technology on their side. Carbon scrubbers and extractor fans do a great job at removing terpenes from the air. However, some still get through.

As well as purchasing strains based on your aromatic preferences, you should also consider your circumstances. If you are growing in the middle of nowhere, or in a legal country or state, you can choose the stinkiest bud around. You can enjoy the full force of aromatic varies such as:

In contrast, those growing in busy metropolises or illegal regions should try and select less smelly varieties. Thankfully, some strains are much more subtle in their aromas, including:

Cannabis effects

As the third pillar of strain selection—and the most important for many smokers—every cannabis user should carefully consider the effects of a strain before buying and sowing seeds.

In the same way that each strain smells and tastes different, they also have distinct effects. Although most varieties produce high levels of THC, CBD, or both, they are still capable of producing wildly different sensations.

Cannabinoids create the foundation of every high, but terpenes contribute unique and powerful effects of their own. For example, the terpene myrcene brings a stoning sensation to the table, often associated with indica genetics. In contrast, limonene creates a cerebral and energising high often attributed to sativa genetics.

Different chemical profiles in cannabis are more suitable for different occasions. Some are ideal for kick-starting your day, some are perfect just before bed, and others bring you to life during social situations.

Check out the best strains for each scenario below.

  • Wake and Bake

Starting your day with cannabis can go one of two ways: perfect or unfortunate. The outcome of blazing before you even get out of bed largely depends on the strain you choose to smoke. Some varieties will make you want to put your head back on the pillow, whereas others will prompt you to throw off the sheets, jump in the shower, turn on the coffee machine, and smash all of your goals for the day.

To obtain that morning glory, you’ll need to choose a strain rich in energising and motivating terpenes. Lemon Shining Silver Haze does a superb job at enhancing the senses and catalysing creative thoughts. Her THC level of 21% and citrus terpenes work as a herbal espresso to turn on the mind in the morning.

Sour Diesel also works wonders at motivating the mind just before breakfast. She exerts a clear-headed high that gets you in the mood to work, without overwhelming the senses or sending your mind to the cosmos.  

  • Socialising

Much like cannabis can wake you up or put you to sleep, the herb works in one of two ways when it comes to socialising. Some varieties can make you more introverted and confined to your own head, and some can really help you open up.

Before heading to a party, load up a bowl of Euphoria for a warm and gentle feeling that will enhance connections with both friends and strangers. This sociable strain packs an equal quantity of THC and CBD. The psychotropic cannabinoid puts the mind in a bubbly and talkative state, while CBD takes the edge off any feelings of nervousness. 

  • Inspiring

Whether you plan on spending the afternoon painting, writing, or playing music, cannabis can enhance the creative process. Tap into deeper flow states and lose yourself in moments of blissful creativity with the help of the herb.

Chocolate Haze never fails to hit the mark before entering the zone of creativity. This tasty cultivar harnesses a THC level of 20% and sweet, sugary terpenes to catapult the mind into a state of focus, motivation, and immense creativity.

  • Relaxing & Sleepy

Sometimes, you just need to kick your feet up, sit back, and treat yourself to some downtime. Life gets busy, and, if we’re not careful, we can find ourselves lost in a world of worry. The right cannabis strains can ground us and help us feel at peace.

When you’re in the mood for some rest and relaxation, take a bag of Northern Light buds into the forest and string up a hammock. Blaze up and feel your muscles melt as the weight of the world is lifted off your shoulders.

Alternatively, snuggle up on your couch, put on your favourite film, and roll a big cone of Royal Gorilla. It only takes a couple of tokes from this strain to feel your worries wash away. With a THC level of 27%, you’ll find yourself melting into a puddle of bliss before you get halfway down that joint.

  • Munchies

While the munchies occur as a side effect of smoking weed, some people actually blaze up just to feel this sensation. Not only does food taste ten times better after a joint, but getting creative in the kitchen while high is an excellent way to connect with friends!

Pineapple Kush descends from legendary parent strains Pineapple and OG Kush. Her indica-dominant genetic profile and high quantities of THC will endow you with an appetite you’ve never experienced. Get ready to raid the fridge.

Somango XL also sends hunger through the roof. Sure, her stoning high fuels the appetite, but the very taste of her fruity terpenes will instantly make you crave a refreshing smoothie or a bowl of juicy melon and mango.

  • Soothing

Cannabis can soothe both the body and mind. Whether you’re feeling agitated and full of nerves or super sore after a hard workout, several strains can help you feel great in no time.

Stress Killer Automatic CBD soothes the soul and brings about a very real sense of peace. After a hard day of work, make yourself comfortable and fire up these flowers in a joint or vape. Feel a wave of relaxation wash over your mind, eliminating rumination and replacing it with contentment.

Royal Highness helps to soothe the muscles and relax the body. Much like soaking in a warm bath, this strain reduces tension, increases bodily awareness, and offers an incredible option before a stretching session to really tap into that mind–muscle connection.
