Best Sites to Buy Cannabis Seeds Reviewed
- Top seed bank with US shipping - I Love Growing Marijuana
- Best for first-time growers - Crop King Seeds
- Largest selection of strains - Seedsman
- Best for fast shipping to the east coast - Quebec Cannabis Seeds
1. I Love Growing Marijuana (ILGM) - Best Quality Seed Bank Overall
- Company has 25+ years' experience
- High quality CBD & medical marijuana strains
- Plenty of strains to choose from
- Can buy complete grow kits
- Shipping can be slow
The site’s owner, Robert Bergman, has been growing and selling marijuana seeds for over 25 years, so he definitely knows his stuff. You’ll find an excellent variety of seeds on offer at their site, including a variety of mix packs if you just want to try something new.
Everything is laid out in such a way as to be accessible to beginners, but experienced growers won’t feel like they’re being talked down to, either.
In addition to letting you buy marijuana seeds, they have complete grow sets that offer you everything you need to get started on the right foot. They also host forums where you can discuss any issues you might have with like-minded hobbyists.
Shipping can take a bit of time, but it’s reliable, so it’s a good tradeoff in our opinion.
2. Crop King Seeds - Best for Beginner Growers
- Lots of information for beginners
- 24/7 support available
- Quick shipping to the United States
- 80% germination rate guarantee
- Customer service isn’t the friendliest
- Many strains are finicky to grow
Crop King Seeds is one of the most popular marijuana seed banks in business today, and that’s in large part due to how easy they make everything for rookies. It’s okay if you don’t know what you’re doing, as they’ll explain everything in crystal-clear detail.
You can even get free shipping, although you need to spend at least $200 to qualify. Otherwise, you’ll pay between $20 and $40; that total comes with a tracking number and insurance, though.
It could be worse!
Their marijuana seeds have an 80% germination rate guarantee, so you should get results even if you’re brand new to growing cannabis. They also provide guides to help you ensure that your seeds have the best chance of surviving.
3. Seedsman - Best Seed Bank for Strain Selection
- Sleek and polished website
- Lots of autoflowering cannabis seeds, feminized seeds
- Offers loyalty programs
- Many accessories available as well
- Corporate feel may be off-putting to some
- No germination guarantee
Seedsman is a polished e-commerce site that is easy to navigate, with strains listed both alphabetically and by category. You can tell them exactly what features you want in your marijuana seeds (such as high THC or sativa-dominant) and they will recommend the best weed seeds for your needs.
Now that's good service.
They even take that professionalism one step further by offering a loyalty program, helping you to get some free cannabis seeds or big discounts if you order from them frequently. You can get more than seeds, too, as they also sell a variety of accessories for your weed-smoking experience.
However, Seedsman doesn’t offer a germination guarantee, which is troublesome if you're not one of the most experienced growers. If your plants don't grow, then you won't be getting a refund from Seedsman any time soon.
4. Quebec Cannabis Seeds - Best Seed Bank on the East Coast
- Designed for North American climates
- Stealth shipping to US
- Ideal for experienced owners
- Many autoflowering cannabis seeds, feminized seeds
- Only one shipping option
- Fee charged on all credit card purchases
- Minimum order of $70
As you might expect from a company headquartered in Canada, all of Quebec Cannabis Seeds’ offerings are designed to withstand North American climates. That makes them a natural choice for American buyers, and they seem to focus on their United States clientele.
They take their stealth shipping to the next level, as some of their packages include random objects like cards or DVDs. This is to throw the authorities off the scent if you’re buying in an area where buying cannabis seeds over the internet may exist in a legal gray area.
It's not worth the risk!
You’ll have to pay a 3.8% fee if you use a credit card, and you have to spend at least $70 on every order. The whole seed bank is geared towards experienced owners, and anyone who knows what they’re doing will find plenty of high-quality seeds to choose from.
What to Know Before Searching for Cannabis Seeds for Sale
The world has changed quite a bit in the past few years, and while it’s now possible to find marijuana seed suppliers through Google, that may not be the best way to go about your search.
Just because a seed supplier ranks highly on Google doesn’t mean it’s trustworthy, so do your research first.
The internet is a crazy place!
There are some key things you should keep an eye on when searching for cannabis seeds and browsing through different seed banks online. Research things such as:
- How many years they've been in business
- Customer reviews on 3rd-party sites (like Trustpilot)
- Do they offer stealth shipping?
- Do they ship to the USA?
- Can you pay in Bitcoin?
- Are their seeds good for your climate, etc?
- Do you like their strains?
There's a lot of things to consider for new growers before they go buying seeds for marijuana online, so make sure you do your research on these seed banks to find the best match for your needs.
All of the seed banks on our list have been well-vetted, so you might want to try I Love Growing Marijuana or Crop King Seeds.
Seed Bank FAQs
Is it legal to buy cannabis seeds online?
That will depend on the laws in your local jurisdiction, but regardless, it’s much less frowned-upon by law enforcement than it used to be.
In many cases, the worst thing that will happen is that the authorities might confiscate your order, but you shouldn’t get in any legal trouble as a result (be sure to check your local laws first, though).
To combat this, many seed banks offer things like stealth shipping and insurance. These are designed to ensure that your order gets to you safely, or to reimburse you in case they get nabbed along the way.
How do I pick the best cannabis seeds?
Picking the right seeds depends on a variety of factors. The most important, of course, is what type of strain you want to grow. The 3 main types are indica, sativa, and hybrid.
Most plants have an indica-sativa mix, but are heavily weighted to one or the other.
- Sativa - naturally high in CBD, stimulating, boosts energy levels
- Indica - naturally high in THC, relaxing, relieves pain & stress
You can experiment to see which one you like best, and it may be a good idea to buy from a bank that includes free seeds with every order so that you can sample many different types cheaply.
You also need to know whether you’ll be growing your seeds indoors or outside, as it makes a difference in which ones are best for you.
Growing indoors is usually easier, as it gives you more control over the plants, so if you plan on growing your seeds outdoors you’ll need to find a strain that can thrive in your climate.
What types of seeds are available?
Beyond the types mentioned above, you also need to know whether you’re buying regular or feminized cannabis seeds and whether the seeds are autoflowering.
The sex of your seeds is important because only female plants create flowers — and the flowers are what you smoke. That means that male plants are generally considered useless and are disposed of immediately.
If you buy regular seeds, you’ll get a mix of female and male plants. This requires you to learn how to tell the male and female seeds apart, and also to remove the males immediately.
If you don’t, they’ll pollinate the female plants, creating low-quality, seed-filled buds.
Feminized cannabis seeds, on the other hand, will only produce female plants.
These feminized seeds can be more expensive than regular seeds, and you also usually get less in each order, but they’re not as high-maintenance as regular ones.
You still need to double-check them, though, as male seeds will accidentally slip into a bag of feminized cannabis seeds occasionally.
Auto Flowering Seeds
Autoflowering seeds are also designed to be low-maintenance.
With regular seeds, you have to change the amount of light they get at certain times to trigger the flowering process. Autoflowering seeds, however, will flower regardless of any effort on your part.
This means that autoflowering plants can be left to grow outdoors, which is very convenient for amateur growers and experienced growers who want some low-maintenance plants.
Buying Marijuana Seeds - The Bottom Line
If you’re looking for a cheap and convenient way to ensure you always have something to smoke, then buying your own marijuana seeds is definitely the way to go. It takes a little bit of work, but the results are well worth it.
I Love Growing Marijuana and Crop King Seeds are excellent weed seed sellers with stealth shipping and a wide range of seeds to choose from. ILGM's owner has 25+ years of experience and Crop King Seeds has a very impressive range of seeds!
Now that's experience.
Hopefully, the list above will prove useful in your search, so that you can get started on your grower’s journey. Whichever seed bank you use to purchase your marijuana seeds, we wish you good luck on your weed-growing journey!
