Tips for buying cannabis seeds

If you have never grown any weed before picking cannabis seeds can be a daunting task. There is no need to worry you can easily order seeds completely legally online without any problems whatsoever in the UK.

Owning the seeds in itself is not even against the ‘law’. We all know how sensible a law against plants is.

In the UK the whole thing only becomes illegal when the seeds are germinated (I mean, how ridiculous) so there is absolutely no way of this being detected at all unless you are talking about what you are doing online on Facebook or something. Avoid this. You’ll be fine.  Especially if you live in County Durham.  Police forces in Derbyshire, Dorest and Surrey suggested similar decisions.

There are literally thousands of strains to choose from and therein lives the problem. I would recommend spending the money on decent genetics. We don’t have the luxury of cuttings being quite so prevalent in the UK (unless you know the right people) so the only way to get that outstanding quality of weed is to use seeds.

One of the popular new ways to grow is using autoflowering seeds.

These seeds have been around some years now and certain varieties are well worth checking out – they can be a shortcut to high quality cannabis. Some of them only take as little as 60 days from germination to harvest. Trusted varieties I grow again and again include:

Buddha Seeds Magnum – really nice up high, energising happy effect. More about the magnum auto here.
Cream Mandarine Auto Incredible, high yielding autoflower with strong but functional effects.
Dinafem Cheese XXL – great yielding auto with strong stone.

If you’re growing outdoors, don’t be put off by the media bullshit about skunk. Outdoor grown skunk (I would recommend Sensi for their Early Skunk in the UK) is a lovely thing and yields very well indeed. Check out this page for more info on outdoor strains and be sure to check out this indepth guide to growing autoflowering cannabis seeds.

And for great value Sticky Seeds is one of the best places to buy cannabis seeds online.

Who are the best UK based seedbanks?

It has been legal in the UK for many years to purchase and sell cannabis seeds. You don’t have to worry about legal action if you want them shipped to you from a different location.

Once the seeds have sprouted, the alleged ‘offence’ has then taken place according to current UK legislation. Until then, everything is fine, as far as the law is concerned.

There are some places of the United Kingdom that are more dangerous than others if you are merely cultivating a few plants for your own use.

The police in County Durham do not actively pursue people who cultivate their own food, thus it is important to find out what your local situation is. Similar remarks have been issued by police in Dorset, Derbyshire, and Surrey in the past.

In the UK you may be able to obtain a ‘Cancard’ if you’re growing cannabis for medical reasons.

Do cannabis seeds have a long shelf life?

Depending on how long you want to store your cannabis seeds for are there are different ways to treat the seeds.

Storage for the short term (1-2 years)

Put the package in a drawer that you don’t frequently access. That’s it.

For the next year or two, they should be fine where they are.

I’ve done this a lot and had no issues.

Storage for the longer term (1-2 years)

It’s possible to keep the seeds fresher for longer by storing them in an additional bag and storing the jar in a fridge at roughly 4 degrees Celsius. Make sure the package they’re in is light-proof, i.e. no light can get in.

Keep moisture levels low by putting silica gel inside too.

Which brand of cannabis seeds are the best to buy?

Investing in high-quality cannabis genetics is well worth the cost.

Think about the desired effects of the herb prior to purchasing your seeds.

Sensi Seeds, Barney’s Farm, and Delicious Seeds are a few of my personal favourites. Every single one of them has an excellent variety of seeds with a wide range of effects.

It’s hard to beat Delicious Seeds’ Sugar Black Rose for novice growers looking for an easy-to-manage heavy yielding strain with superb stoned effects. This plant is one of my favourites.

It’s no surprise that Dutch Passion’s Blueberry is a favourite in the UK, as it thrives both indoors and out.

In addition to that also check out Mazar, any dedicated smoker will find Mazar to be a super strong acting strain. There are many many others.

Are some cannabis seeds expensive for a reason?

Cannabis prohibition affects the whole cannabis sector, making it difficult to start a cannabis breeding facility where you could cultivate your own seeds today. It takes a lot of time and money to create and distribute seeds successfully.

As you may be aware, the cannabis seed industry has been adversely affected by Brexit. Importing seeds from the European mainland has become more expensive since the United Kingdom left the single market.

If you know exactly what sort of seeds you want, you can find them for less money. Bulk seed suppliers may provide you with cheaper replicas that are frequently just as nice as the originals, so look into that option.

You can buy high-quality weed seeds at lower prices from Sensi Seeds’ Weed Seed Shop, which is operated by the same company.

There are also high end seeds like NL5-Haze which are without a shadow of doubt, worth the extra money. Not a good choice for the outdoors in the UK, unfortunatley but can be grown indoors, if you are patient.

Are feminised cannabis seeds any different?

Growing with feminised cannabis seeds offers a distinct advantage over using regular seeds because they exclusively produce female plants.

Female plants are highly sought after by cultivators because they produce the cannabinoid-rich flowers, or buds, that are harvested for both medicinal and recreational use. In contrast, male plants do not produce these desirable buds.

When using standard ‘regular’ cannabis seeds, growers will encounter a mix of male and female plants in their crop. Identifying and separating the male plants from the females is crucial to prevent pollination. Male plants can be recognized by their seed sacks, which develop before the plant starts to flower.

If male plants are allowed to pollinate female plants, the females will shift their energy from producing buds to developing seeds, resulting in a lower yield of usable cannabis. To protect your crop and maintain the quality of the harvest, it’s essential to remove male plants as soon as they are detected. By doing so, you can avoid unwanted pollination and ensure a bountiful harvest of potent, seedless buds.

More about this here.

What are the best cannabis seeds for medical use?

When selecting cannabis seeds for medical use, it’s essential to consider the chemical composition of the plant, particularly the ratio of two primary cannabinoids: CBD (cannabidiol) and THC (tetrahydrocannabinol). These compounds are known for their therapeutic properties and have distinct effects on the human body.

Cannabis strains with a 1:1 ratio of CBD to THC are often recommended for medicinal use, as this balance can provide significant therapeutic benefits without causing the intense psychoactive effects typically associated with high-THC strains.

CBD is known for its potential to alleviate inflammation, pain, anxiety, and seizures, while THC has been found to help with pain relief, appetite stimulation, and insomnia, among other symptoms. By combining these two cannabinoids in equal amounts, patients can experience the best of both worlds – effective symptom relief without the overwhelming high.

Check out the results for this search to find seeds that are bred to have large amounts of CBD as opposed to THC.

When choosing cannabis seeds for medical use, it’s crucial to research the specific strains and their potential effects on your symptoms or condition. Consult with a healthcare professional familiar with medical cannabis for personalized guidance and recommendations.

What are the best cannabis seeds for novices to use?

There is a lot of advice out there for those who are just starting out.

Embarking on your first cannabis growing journey can be exciting, but it can also be overwhelming due to the vast amount of advice and countless strain options available. Fortunately, some cannabis seeds are more beginner-friendly than others, making them perfect for those just starting out.

Many feminized and auto-flowering strains are ideal for novice growers because they simplify the cultivation process. Feminized seeds produce only female plants, eliminating the need to identify and remove male plants that could pollinate and lower the quality of your harvest. Auto-flowering strains, on the other hand, automatically transition from the vegetative stage to the flowering stage without any adjustments to the light schedule, making them less time-sensitive and more forgiving.

One highly recommended strain for beginners is ‘Northern Lights,‘ a popular and potent option that’s easy to grow. Known for its resilience and straightforward cultivation process, this Indica-dominant strain offers a relaxing, full-body effect that appeals to many users.

Sensi Seeds, a reputable seed bank, has recognized the needs of novice growers and dedicated a full page on their website to the best strains for beginners. You can explore their autoflowering strains and feminized varieties to find suitable options for your first grow.

To further assist your decision-making process, this comprehensive guide on the best cannabis seeds for beginners offers in-depth information and recommendations tailored to those new to cannabis cultivation. By choosing beginner-friendly seeds and arming yourself with knowledge, you can set yourself up for success as you venture into the rewarding world of cannabis growing.

What are the best cannabis seeds for growing in cooler climates?

Breeding early finishing strains that can withstand the lower temperatures and moisture that arrive in the UK in September and October is the best way to grow marijuana in cooler climes.

Growing long-flowering strains like haze and other Sativas outside has been difficult because of the time it takes to ‘complete’ these plants outside, which results in either premature harvest or lasting damage from mould or frost.

New kinds of cannabis seeds have been made available to producers with short summers thanks to recent advances in ‘autoflowering’ cannabis seed technology.

It is now possible to cultivate strains like Power Plant, White Diesel Haze, and a number of others outside in milder climes using autoflowering versions.

These brand-new autoflowering plants are easy to grow because they progress directly from the vegetative stage to the flowering stage without requiring any changes to lighting schedules. They represent a breakthrough in cannabis breeding.

A seed can be sown and a bud harvested in just 70 days, thanks to this new technology. Simple to use, and it reduces the amount of time that seeds need to be exposed to direct sunlight, allowing you to plant seeds in the UK as early as May, June, or July and see excellent results 70 to 80 days later.

Check out this page for more details on the best cannabis seeds for cooler climates.

What exactly are autoflowering cannabis seeds?

Quality of autoflowering seeds has grown tremendously over the last few years.

For these seeds, flowering does not necessitate a change in light pattern; they simply begin flowering after a predetermined time period, often 4-6 weeks.

Autoflowers typically take 70 to 80 days to mature from seed to harvest.

They can easily be stopped from achieving their full potential.

As an example, most autoflowers prefer to remain in their original pot rather than be repotted. This can stunt some auto flowers into dwarf plants with very little yield so care is required.

When it comes to feeding, autoflowering plants are more sensitive than their non-autoflowering counterparts.

You shouldn’t expect the same big harvests as you would from conventional feminised seeds.

Autoflowers, on the other hand, have their place, especially in an English rear garden where you want to keep things low profile.

Find out more about autoflowering cannabis seeds in this guide.

Who do you think are the best weed seed creators?

Mr Nice Seeds has a devoted fanbase and a significant history.

A great deal of seasoned growers I met swear by Barney’s Farm or Sensi Seeds as their preferred seed supplier.

DNA Genetics and Greenhouse Seeds, both of which have been around from the early days, both have many fans. (The DNA Genetics variety of OG Kush remains the greatest Kush I’ve ever experienced, a fantastic high I will never forget.)

For as long as I can remember, Dutch Passion has also been a major player in the cannabis seed industry.

I am, however a big fan of the Spanish leaders, such as Sweet Seeds and Delicious Seeds, but there are many others worth checking out like Philosopher Seeds.

There are prior cannabis cup winners listed on this website if you’re interested in learning more.

Do certain seed banks ship cannabis seeds to the US?

Many seedbanks do.

And the States now has a growing number of its own US-facing stores, some of which are new and some of which have been around for a long.

Crop King Seeds have been around for a while and are highly regarded.

Other names include Mary Jane’s Garden, Beaver Seeds, Seed Supreme and Rocket Seeds.

Some European seed banks, such as Original Sensible Seeds will also ship to the United States. See this page for more information about cannabis seedbanks that ship to the US.

Barney’s Farm now have a dedicated US website where they offer marijuana seeds for sale.

Who are the best UK based seedbanks?

If you are looking for a company to buy cannabis seeds from who are actually based within the United Kingdom then it is worth mentioning that since Brexit happened many companies relocated and are now sending seeds from outside the UK, adding more time to delivery and sometimes complicating the whole buying process.

See this post for a list of seedbanks specifically located in the UK. And this post for the Best Seedbanks in Europe.
