Seedshop Top Lists

The cannabis industry is ready to advance into the year of 2020. Get ready for some fresh and powerful genetics to hit the scene.

A new year means new innovations, new products, and a new generation of carefully bred and potentially game-changing cannabis strains. A new year also means many more smoke sessions are on the horizon, whether they be at home with friends, in the buzzing atmosphere of music festivals, or out in a blissful setting in nature. Below is a list of the best strains to check out in 2020, along with a few additions of new and exciting strains to keep an eye out for.


Just like every year, some strains will steal the spotlight. In the list below, we'll discuss some of the smashers of 2020, so let's get to it!

To kick off our list of the best strains you'll find in 2020, we wanted to show you three autoflowering strains and three photoperiods. Why, you wonder? Well, there are all sorts of growers out there. Some have all the time and expertise they could ask for; others, of course, might be under a time crunch, or still learning the ropes.

We want to show you that there's quality cannabis out there for everyone, regardless of time and experience constraints. There are a lot of fine strains we could have included here, but these are our personal favourites.


Amnesia Haze Automatic (Zamnesia Seeds)

Amnesia Haze has been one of the most iconic sativas out there for years, proving it to be a popular choice for growers in the past, the present, and most likely in the future. As is the case with many iconic strains, though, only the most experienced and patient growers reap the benefits. This, however, is a different beast than the original icon. Mixing its genetics with ruderalis, the creators of Amnesia Haze Automatic offer a way to grow this legend with far less headache. Packing an impressive 18% THC, this strain induces the same bright, euphoric high as the beloved original.

Expect to wait just 10–11 weeks from seed to harvest, with each plant offering 500g/m² indoors and 150g/plant outdoors. Either way, your plant will reach a height of 1.5m.

Green Gelato (Royal Queen Seeds)

Yet another recognisable name, Green Gelato is known to pack one of the heaviest punches of any strain out there. It should be no surprise, then, that Green Gelato Automatic is one of the most powerful autoflowering strains available. Even photoperiod strains have a hard time competing with its daunting 24% THC content. Slightly sativa-dominant, this strain is perfect for creatives seeking a mental energy boost. The terpene profile is similar to the original, hitting the air and your taste buds with sweet and citrusy notes.

You'll only need to wait 9–10 weeks for your seeds to become beautiful, lush plants. Indoor yields are usually around 400–450g/m², while you'll get 100–175g/plant outdoors. Expect plants to reach up to 120cm in height both indoors and out, although indoor plants can be as short as 70cm.

Original Auto AK (FastBuds)

Even casual smokers will have some level of familiarity with the iconic AK-47. If you like sativas, chances are you've even smoked it before. Carrying on the legacy, Original Auto AK features everything you'd want in an autoflowering strain, and more. It clocks in with an impressive 21% THC, and offers the user an energetic and euphoric high. You'll be transported deep into the woods as soon as you light it up, with earthy, piney, and floral notes filling the air. If you pay enough attention, you'll notice the subtle presence of citrus as well.

Even relative to other autoflowering strains, this one pops out of the ground quick, with just 60 or so days between planting your seed and picking your crop. Even while standing at around 80cm or less indoors, it can still provide between 400–500g/m² of buds.

Dos Si Dos 33 (Barney's Farm)

Switching to feminized photoperiod strains, Dos Si Dos 33 is a potent combination of Dos Si Dos (Girl Scout Cookies and Sunset Sherbet) and Gelato 33. As you might suspect, the flavour and aroma are a nuanced cacophony. Notes of mint and sweet lime hit the tongue, with an aroma reminiscent of refreshing sherbet and fresh-baked cookies. Your nugs will have a minimum 22% THC content, while the strongest can reach a staggering 28%. This leads to an interesting experience with the 60/40 indica/sativa split, offering a radiant initial rush that calms into a stoney sensation.

These plants only need 60–65 days to flower, and the yields are insane. You'll get around 700g/m² indoors, but outdoor growers walk away with the real prize of 2000g/plant.

Watermelon Zkittlez (Pyramid Seeds)

Combining OG Eddy with Watermelon Zum Zum #3, our friends at Pyramid Seeds would like to introduce you to Watermelon Zkittlez. It's a pure hybrid (50/50 indica/sativa split) containing 25% THC. This means it'll hit you with a variety of sensations. It begins with an energetic head high lasting 1–2 hours, cooling down and relaxing your body after. The flavours are as sweet as the name suggests, with images of sweet watermelon and other fruits appearing in the mind upon first puff. It permeates the room with these aromas as well, with each note emphasising the other.

Being ready after just 60 days of flowering indoors, the 400g/m² yield this plant offers is quite impressive. If you're growing outdoors, though, September will show you obscenely large yields of 750–1000g/plant.

Runtz (Zamnesia Seeds)

It may be called Runtz, and it may be one of the newest strains in our catalogue, but best believe, it's not the runt of the litter. Being the descendant of Gelato and Zkittlez, you can easily see it becoming one of the big dogs soon enough. In fact, with a comically high 27% THC content, it already barks louder than most of them. Dog metaphors aside, this hybrid is perfect for relaxing the mind without locking you to the couch. Take a whiff of the nugs, and you'll feel like you've been flung into a giant bag of fruity candy, with the taste only adding to this sensation.

Indoor plants can be as short as 80cm and as tall as 130cm, yielding 450–500g/m². Outdoor plants, however, surge up to 180cm and provide around 400–450g/plant if you treat them right.

To finish things off, these strains are new to the game, with some yet to even appear in our store. What isn't there to love about a fresh face, though? And believe us, these are some of the freshest you'll find on the market.

All these strains will be available at Zamnesia soon! Keep an eye on our social channels, such as Facebook and Instagram or subscribe to our newsletter to make sure you are the first to know. Now, let's see what 2020 has to bring...


ZZ Punch (Zamnesia x Royal Queen Seeds)

No, this isn't ZZ Top's official strain. What ZZ Punch is, however, is a beautiful collaboration between Royal Queen Seeds and ourselves. We combined Sweet ZZ, their cultivar, with our own Purple Punch in an effort to make a powerful, relaxing, and delicious indica. Key word: delicious, cause you'll wish the fruit/candy/berry party on your tongue would never end. It hits just as good as it tastes, too! With a hefty yet manageable 22% THC content, this indica-dominant strain is perfect for a kick-back with friends or low-key alone time.

You'll only have to wait around 65 days for the flowering phase to wrap up. It'll be a decent harvest too, with indoor and outdoor yields offering approximately 500g/m² and 500g/plant respectively. If you want more bud sites and a taller plant, we suggest topping the plant during veg.

ZZ Punch is a limited edition collabo between Royal Queen Seeds and Zamnesia, so if you are late to the game, they just might be sold out. But don't fret–Zamnesia is constantly working on new strains with the help of talented and experienced breeders from reputable seedbanks, so check in with us regularly to find out what's cooking!


THC-Victory (Dutch Passion)

Standing out from all the others here, THC-Victory is known for containing the newly harnessed THCV. Standing for tetrahydrocannabivarin, THCV is a cannabinoid that's captured the interest of the cannabis community. It slightly suppresses the effects of regular THC, although it doesn’t cancel them out completely. Given that, the balance between the two cannabinoids (with 6–8% of each present in the buds) is perfect for the occasional smoker. It leans towards the sativa end of the scale, offering an enjoyable head high without making you too tired.

Growing it won't tire you out, either. Although it's slow during early vegetative growth, it picks up speed later on, and it'll take about 11 weeks to flower. Furthermore, we generally recommend you stick to growing this strain indoors. It's not in our store just yet, so make sure to keep an eye out!

El Patron (Royal Queen Seeds)

We have our good friends at Royal Queen Seeds to thank for this one. It isn't even available to the public yet, and it's already winning awards! Specifically, it took first place in the Common Weed Grown in Soil category at the Highlife Cup 2019. For those unfamiliar, the Cup is a prestigious cannabis industry event where judges do weeks-long blind tests of the competitors, consuming and judging each strain in every possible manner. After that arduous process, the secret RQS project clinched first place in one of the most important categories.

Do we want to give you more information? Of course! Nothing would bring us more pleasure. However, we're serious when we said this was a secret project on their part. All you can do in the meantime is check back with us to see when it finally goes up on our site!
