10 places to buy the best cannabis seeds that ship to the UK

Just because seed banks online are popping up everywhere doesn’t mean every resource is trustworthy. How can you know who to trust when growing weed is illegal in the UK?

Not to worry – we’ve compiled a list of the best cannabis seeds that ship to UK, as well as a guide to ordering seeds for the new British buyer.

Is Buying Cannabis Seeds Legal In The UK?

As you might have heard by now, cannabis is illegal to possess, sell or grow in the UK, even though almost every decent human being does it.

Nevertheless, getting charged with unlicensed production or trafficking is a headache, as cannabis is still considered a Class B drug, carrying a maximum penalty of 5 years in her majesty’s slammer.

Oddly enough, it’s not necessarily illegal to order marijuana seeds from a legally established overseas seed bank, like the ones reviewed on our list.

Legally speaking, no one can prove what you’re planning to do with those seeds, and whether or not they’re purely for collectible, personal use, or research purposes only.

You need to spark up a J and do some… “research”, yeah?

– You can buy marijuana seeds as a “novelty item”
– Customs still might confiscate the weed seeds
– The best cannabis seeds companies offer delivery guarantees
– You can also get “discreet packaging” or “stealth shipping” to the UK where the seeds are hidden in everyday items

Top 10 Best Seed Banks That Ship to the UK

1. Crop King Seeds – Best Overall Cannabis Seeds

Pros

– Wide selection of seeds
– Guaranteed germination & delivery
– Founded in 2005

Cons

– Not much in the way of discounts

Crop King Seeds is one of the longest-standing and most successful marijuana seed banks in the world and still offering the best-selling strains and new hybrids.

From top sellers like Dwarf Low Flyer Autoflower seeds to feminized seeds like Black Indica and Durban Poison, the site has a huge selection to choose from.

You can also expect “growing marijuana seed” guides, 24-7 chat support, a charge-free telephone number, and discreet packaging to the UK.

We liked CKS because of its wide range of strains and new seeds, with 500 new seeds released for the year.

The company offers two guarantees, one for germination, and the other for delivery, once you pay for Express Registered with Tracking.

2. Seedsman – Best Variety for Cannabis Seeds in UK

Pros

– Founded in 2003
– 40 promotions throughout the year
– Bitcoin discounts

Cons

– Loyalty program currently on hiatus due to “social sharing abuse”
– Difficult process for any lost orders

Seedsman drives a hard bargain with discount deals like 3 for 2, and up to 25% off Bitcoin purchases. There are roughly 40 different promotions every year, all averaging about 20 percent off the listed price.

But what makes Seedsman’s seed bank remarkable is its large selection. The company gets its catalog from over 80 trusted breeders all over the world and can offer as many as 1,500 strains to UK weed growers like yourself.

Customer service is well-reviewed, though it’s only email-based, and they are forbidden to provide any growing advice. Fortunately, you can also purchase some guides on how to grow your own “collectible seeds”, if that’s something you might fancy at some point.

3. Quebec Cannabis Seeds – Best Bulk Sales for UK Customers

Pros

-Better for bulk & mix pack deals
-Germination guarantee
-Founded 2013

Cons

– Not clear whether they offer a delivery guarantee

Quebec Cannabis Seeds promises consistent quality on cannabis strains, with “optimum THC and high CBD levels.” While they do feature top-sellers like Auto Bruce Banner Feminised Seeds and Amnesia Haze XL auto-flowering seeds, their most exciting deals come in the way of mix packs and bulk seeds.

You can buy cannabis seeds mixes of feminised, auto-flowering, fast version, and Quebec Gold quality, in packs of 100. All packaging is handled discreetly and seeds are shipped inside inconspicuous items.

That’s just a DVD in the post… wink wink.

Seeds are guaranteed, and the company has confidence in its 80% germination rate. While confiscated packages won’t get you a refund, QCS is pretty good at making sure their seeds don’t get caught at customs.

4. Marijuana Seeds NL – Best Deal for Free Seeds

Pros

– Rewards program with money back the more cash you spend
– Accepts multiple forms of payment
– Free seeds with most purchases

Cons

– Not much in the way of guarantees

While much of the world was still debating the magic of cannabis, Amsterdam was busy producing it – and since 1999, providing individuals and companies with cannabis seeds.

We love you, Holland.

The most original of UK seed banks is Marijuana Seeds NL, offering a wide range of seeds, from feminised to autoflowering seeds and regular seeds, to special value packs for potency, taste, and environment.

The company is proud of its quality genetics and its founders traveled the world to find the best marijuana strains and develop testing procedures that would ensure stability. You can also expect “double free” seed deals, depending on the season.

Regular shipping is free after £55 and stealth shipping is free after £100.

5. MJ Seeds Canada – Best for Discreet Packaging

Pros

– Founded 2009
– Accept Paypal, bank transfer, & other payment methods
– Very discreet packaging

Cons

Questionable germination guarantee

While MJ Seeds Canada does have a high germination rate, their priority appears to be affordability in shipping and cannabis seed prices.

See also  Weeds And Seeds

The germination guarantee is not as highly touted as the delivery guarantee, but the delivery is guaranteed when you pay for tracking and insurance.

However, they take their discreet seed billing and packaging seriously and alternate shipping methods regularly, so as not to build a pattern and arouse suspicion around your weed seeds.

The store’s 24-hour shipping policy is also unique, because of the fact that MJSC has multiple stores, offices, and warehouses to ship from.

6. Sonoma Seeds – Safest Way to Buy Marijuana Seeds Online

Pros

– Many payments supported, including cash
– High germination rate & guarantee
– Telephone customer support

Cons

– Not as much in the way of discounts

Sonoma Seeds is based in Canada and offers 300 Canadian dollars (around 175 GBP) for international shipping, which is all well and good. However, compared to $200 in free shipping offered by the likes of Crop King Seeds and the like, it’s a bit pricier.

Still, one of Sonoma’s advantages lies in the variety of supported payment methods, including bank transfers, Bitcoin, credit cards, and even carefully hidden cash, which is untraceable.

Other positives include an 80% germination rate, 500 strains to choose from, and premium customer support, including a telephone line with business hours.

What makes Sonoma Seeds unique is the flexibility of payment options, guaranteeing your privacy and giving you options.

7. SunWest Genetics – Most Innovative Cultivation Methods

Pros

– 500 strains to choose from
– Phone & internet support
– Free cannabis seeds included with larger purchases

Cons

– Not a lot of information on the company or its practices

SunWest Genetics focuses on improving the genetics of cannabis, including diversifying the gene pool of strains. Specifically, the company tries to improve strains for medicinal purposes and breed new varieties with additional benefits.

The company is outspoken about its quality control process but did not provide much information in the way of growing fundamentals for newcomers.

So you’d better know how to grow weed in the UK!

In terms of presentation, they have a lot to offer, with a variety of strains (over 500), fast and reliable phone and email support. The company is quick to stand by its products, offering a guarantee for quality and germination, which stands at 80%.

8. Rocket Seeds – Best for Hard to Find and Popular Seed Strains

Pros

– Works with other UK seed banks to find certain seed strains
– Germination guarantee
– Free seeds with higher purchases

Cons

– More like a convenience store than a unique brand

Not only does Rocket Seeds work with the world’s most successful breeders, but the company also goes out of its way to search for multinational sources of new strains.

The good news is you can find almost everything from here, from feminized seeds like 3 Kings and Acapulco Gold, or AK-47 auto-flowering, or even fast version seeds like Baklava MJ which can deliver a fast yield with little maintenance.

Rocket Seeds is such a team effort that you might find yourself working with the likes of Beaver, Crop King, Sunwest, and Mary Jane’s Garden – other seed banks that can find those hard-to-get strains.

It’s basically GoCompare for weed seeds.

9. Mary Jane’s Garden – Best Shipping Deals on Weed Seeds

Pros

– Reputation for high-quality seeds, no deformities
– Established 2003
– 90% delivery rate to UK
– Same-day shipping

Cons

– No telephone support

Mary Jane’s Garden has had almost 20 years in the business and has developed a reputation for a wide selection of strains and high-quality seeds.

What Mary Jane highlights is a more exacting selection process, weeding out the weed seeds (get it?) that might be damaged or unnaturally formed.

You’re left with the crème de la crème!

The delivery rate is 90% to the UK, above average, meaning the company knows how to secretly package your seeds!

Surprisingly, Mary Jane has one more distinct advantage over its competitors – a same-day shipping policy that beats even our top selection.

10. Beaver Seeds – Best UK Seed Banks Customer Support

Pros

– Established 2009
– Same-day shipping to UK
– Guaranteed delivery with extra insurance & tracking options

Cons

– Not a strong assurance of a germination guarantee
– Not as many discounts as competitors

Beavers Seeds cuts out the low-quality affordable stuff and stocks only the highest grade of cannabis seeds. You’ll find popular brands like Gorilla Glue and Banana Punch to bulk Indica and Sativa regulars.

The company offers same-day UK shipping, a rarity, not to mention a tracking system to practically every country on the globe.

Besides accepting multiple forms of payment, including cash, and guaranteeing a germination rate, what truly impressed us about Beaver Seeds is its 24/7 seed bank telephone support.

Cannabis Seeds UK FAQs

How do seed banks ship to the UK?

While there are many seed banks that ship to the USA and countries where weed is (somewhat) legal, it can be a bit trickier to buy weed seeds in the UK.

Because growing cannabis seeds in the UK remains illegal, practically all reviewed seed banks offer discreet and stealth packaging.

Not only does this involve carefully selected phrases on billing and address labels, but even within the package itself, the seeds are often hidden.

Marijuana weed strains can be clandestinely stored in:

– Greeting cards
– Christmas gifts
– Books
– Catalogs
– Toys for children
– DVD cases
– Video game cases
– And more!

Some companies, such as Crop King or Seedsman, will often change up their shipping methods so that local laws or UK customs don’t become suspicious.

What’s the safest way to buy UK cannabis seeds online?

Many online seed banks in the UK now offer Bitcoin or other cryptocurrency purchases, which are much more difficult for customs to catch and trace.

Some companies like Sonoma Seeds or Beaver Seeds even allow you the option of paying in cash, which is completely untraceable.

You simply send the money wrapped and hidden with your order, and if it’s not confiscated, (which is fairly rare) you get your order back.

You can even track your package if you order the higher-end shipping option.

What different strains of marijuana can you grow in the UK?

Remember, that some marijuana seeds will only excel in special climates and environments. When planning to grow any plant in the UK, you must consider the UK weather, which is typically rainy, cold in the winter, and even slightly cool in the summer.

Basically, our weather is crap.

Marijuana flowering is seasonal, and germination peaks around late spring while harvesting begins around autumn. Many avoid outdoor growing in the U.K., naturally because of anti-marijuana laws, but also because of the rainy climate.

Autoflower seeds will grow easier in most environments and might be the wiser choice for the newcomer, not to mention the “fast-growing” packages, which are made to thrive in most environments.

Easy to Grow Marijuana Seeds for the UK

Some easy-to-work-with strains that are quite popular among newcomers in the UK include:

– Skunk Fast Version
– White Russian Fast Version
– Northern Lights Autoflower
– Critical Autoflower

Skunk and White Russian are set apart from the others because they are called fast-version cannabis plants, made for territories with short seasons, and with expectations of a fast harvest.

Fast version cannabis strains yield results faster than normal flowering times, because of feminised and crossed genetics, mixing photoperiod and automatic female clone genes.

They are also not the same as auto-flowering strains, even though they are also made to grow unusually fast. However, fast version cannabis strains are not autoflower, like Northern Lights or Critical. These are “photoperiod” strains, which are light-dependent and tend to harvest early.

Autoflowering strains like Northern Lights are known to be compact, relatively fast, and with a distinct honey-aroma. It’s considered an easy plant to grow and yet with high THC levels.

Critical is also a well-known strain for both indoor and outdoor growers and is a nice compromise between high yield and reduced flowering time. Critical is appreciated because it can grow in even colder climates.

All of these popular strains are available at sites like our top pick, Crop King Seeds.

Fun but Challenging Marijuana Seeds to Grow in the UK

– Bruce Banner
– Gorilla Glue
– Dos Si Dos Girl Scout Cookies

Bruce Banner, named for obvious reasons, packs a hulk of THC, up to 30 percent! No wonder it’s a hobbyist’s favorite, and known for not only cerebral highs but also more calming sensations.

Gorilla Glue is a common strain name you will find among UK growers, because of its high THC content, as well as its medicinal use for pain relief. It’s more about relaxation and euphoria and is one of the top sellers of most seed sites, including Seedsman.

Finally, how can we not brag about Dos Si Dos, a Girl Scout Cookies / Face-Off hybrid that accentuates the already-celebrated taste with an even stronger high? 70% Indica and flexible for indoor or outdoor growing, fans love the strain for its medicinal power, and ability to relieve depression and insomnia.

Best Marijuana Seed Banks That Ship to the UK: The Takeaway

We particularly admire Crop King Seeds with its 24/7 customer support, its double guarantee, (for germination and delivery), and the wide variety of strains.

See also  Growing Butterfly Weed From Seed

However, we are obliged to admit Seedsman had the better reputation on Reddit and other social media sites, so it was a very tight race to the top spot.

If you’re ready to take the next step and start becoming the cannabis hobbyist you always dreamed of, start your journey by working with reliable marijuana seed banks that ship to the UK.

Look for reputation, quality, discounts, and a company that’s ready to help you find your way. Good luck!

The Highest THC Seeds

An in-depth review of the 15 highest THC seeds available. Discover a world filled with bone-crushing indicas and psychedelic sativas and find high THC seeds for sale.

When you want weed that will knock you off your feet, there’s no better choice than high THC seeds.

Cultivators worldwide prioritize high THC seeds because most cannabis enthusiasts seek the most potent strains available. Whether for medical or recreational purposes, the concentration of THC is paramount.

Many medical marijuana patients seek weed that contains upwards of 30% THC to nip discomfort in the bud. Alternatively, recreational marijuana enthusiasts seek cannabis that exceeds the 35% THC mark to explore the mind’s boundaries. Regardless of your reason, choosing a strain with high THC is almost always an excellent choice.

High THC seeds, however, are not easy to come by. The vast majority of the highest THC strains are not for sale because they are closely guarded. Due to their rarity, high THC strains typically form the backbone of a cannabis seed company’s catalog.

Furthermore, the highest THC strains are kept as an ace-in-the-hole during cannabis competitions, such as High Times or Spannabis. Overall, you’ll be hard-pressed to coerce a breeder to give up a legendary cutting of a high THC strain.

Luckily for you, a handful of coveted high THC seeds are available — if you know where to look. Read along to discover the criterion to select the highest THC seeds for your needs.

How to Choose The Highest THC Seeds

As a cultivator, you must search for a cannabis strain that ticks all the boxes — not just THC potential. What use is a high THC strain if it tastes terrible, or worse, yields a handful of grams?

Overall, the point is to find the highest THC strains that’ll put you down-for-the-count while being enjoyable to grow and experience.

Now, let’s take a look at the different aspects that you must consider before you buy high THC seeds.

THC Level

If you want high THC seeds, this is the first aspect that you need to look at.

Sure, 25% THC is potent, but why not find seeds that contain 35% THC? Once again, it’s all about you. Therefore, only you can decide if a 20-30% THC strain is right for your needs.

Effects

Are you searching for an indica, sativa, or hybrid?

The type of cannabis strain makes a massive difference, so you must choose accordingly. The last thing you want is to grow a psychedelic sativa only to realize you suffer from anxiety.

Overall, you must look at the effects of a high THC strain and determine if it produces results that you will enjoy.

Grow Difficulty

The grow difficulty of a strain is a vital aspect to consider.

If the high THC seeds that you purchase are challenging to grow, your overall experience will suffer — let alone the final yield. In other words, you must choose high THC seeds that match your skill level.

Terpene Profile

Terpenes make the world-go-round.

Nobody enjoys bland weed that doesn’t smell or taste like anything. Therefore, you must choose high THC seeds that contain a unique terpene profile.

Uniqueness and Personal Preference

Whether it’s for bragging rights or because it’s a personal choice — there’s nothing like growing high THC seeds that no one else has.

You must understand what you want in a cannabis seed with high THC potential.

Value for Money and Effort

Ultimately, you must decide if the high THC seeds in your shopping cart are worth your money, time, and effort.

The 15 Highest THC Seeds

Everyone is different.

In our years in the cannabis industry, we’ve seen it all, from cannabis veterans with iron-lungs pass out after a one-hit-quit to beginners burning down entire joints without feeling anything. The point is — every person reacts differently to THC.

With our experience in mind, we’ve curated a list of the 15 highest THC seeds that’ll make your mind soar through the clouds or blackout on-the-spot.

From blackouts, couch-locks, and tripped-out effects — our list of the 15 highest THC seeds is a must-read.

#15 Fruity Pebbles

Fruity Pebbles is a mouth-watering treat that packs a flurry of punches that will leave you utterly dazed.

If you’re ready to fill your bowl with potent Fruity Pebbles weed, look no further than these high THC seeds.

#14 AK-47

Although AK-47 weed isn’t as menacing as the actual object it’s named after — it’ll blow your mind away. If you’re on the hunt for a sativa-dominant strain that boasts cerebral effects, these high THC seeds are it.

AK-47 isn’t only renowned for its heavy-duty potency and how easy it is to grow. Whether you’re a beginner or a professional that grows indoors or outdoors, AK-47 seeds never fail to get the job done.

Once you finish harvesting AK-47’s trichome-rich flowers, prepare yourself for a mouthful of honey, white pepper, cardamom, and pine sap. As the flavors escape your mouth, an urge to dance, jump, and howl-at-the-moon will overtake you.

If you need the highest THC strain to get the party started, look no further than AK-47 seeds.

#13 Chemdawg

Are you looking for high THC seeds that offer copious resin coverage, record-breaking yields, and long-lasting effects?

Meet Chemdawg (or Chemdog) — the California hybrid that’s coveted by indoor and outdoor growers worldwide.

After years of experience with Chemdawg, we can say without a doubt that this strain is a genuine crowd-pleaser. Cheshire cat grins to body-numbing relaxation, Chemdawg is a versatile strain that packs a THC department punch.

Beginners beware — Chemdawg buds are loaded to the brim with THC potential. If you overindulge, you might find your mind floating into the sky while your body gets buried in the ground. However, if you’re after a cannabis strain that offers a cash-crop potential while maintaining an exceptionally high level of THC — Chemdawg seeds are a must-buy.

Bananas and Kush — what’s not to like?

Banana Kush is, by far, one of the strongest medical strains available. If you’re a medical marijuana patient that needs to reduce pain, insomnia, and stress — Banana Kush seeds are all you need.

Furthermore, Banana Kush is an easy strain to grow. Cultivating Banana Kush plants is straightforward; however, it does grow slowly. As long as you can provide Banana Kush with 3-weeks of vegetative growth, you will be rewarded by robust plants that can hold the hefty flowers.

The terpene profile of Banana Kush is, you guessed it — filled with ripe banana, spice, hashish, and sweet floral undertones. The effects of Banana Kush are characterized by uplifting creativity, body-numbing relaxation, and pure bliss.

However, don’t underestimate Banana Kush. At 27% THC, Banana Kush is ranked as one of the highest THC strains.

Commonly known as Sunset Sherbert, Sunset Sherbet is hailed as one of the best cannabis strains of all time. One of Sunset Sherbet’s notable traits is its ultra-high THC content. At 25% THC and above, Sunset Sherbet is some of the most potent marijuana you’ll ever experience.

Furthermore, Sunset Sherbet’s buds are gorgeous and decked from top to bottom with resin. However, Sunset Sherbet’s beauty and terpene profile are deceptive. As you fall into a trance with Sunset Sherbet’s buds, you may take one hit too many.

Remember, Sunset Sherbet is one-hit-quit weed, so you must start slow.

Aside from Sunset Sherbet’s outrageously relaxing nature, it’s easy to grow. We can’t stress it enough — Sunset Sherbet wins on all fronts, from yield potential to flavor.
Sunset Sherbet’s ultra-high THC seeds sell out quickly, so if you find these high THC seeds for sale, don’t sleep on them.
