A guide to buying cannabis seeds
The first couple months of the year is a great time to start planning your cannabis garden to get a head start on the outdoor growing season, which roughly runs from March to November, depending on where you live.
Navigating the cannabis seed market can be challenging when states have different degrees of legality. This guide will answer your questions on buying seeds so you can be on your way to growing your own cannabis.
Is it legal to buy marijuana seeds?
Marijuana seeds are considered a cannabis product just like flower, edibles, and concentrates. Their legality depends on which state you live in. People living in states with adult-use legalization can buy, produce, and sell seeds within their own state, but seeds can’t cross state lines. People living in states with medical marijuana legalization can only buy seeds if they have a medical card.
Seed banks exist outside of the US and can sell them for “souvenir purposes,” but it is illegal to bring seeds into the US and Customs will seize any cannabis seeds they find in packages or on a person.
Where can I buy cannabis seeds?
Many world-renowned seed banks are overseas in the Netherlands, the UK, Spain, and other countries where cannabis laws are less restricted. Seed banks provide seeds from a variety of different breeders.
In states with adult-use legalization or a medical marijuana program, you can buy seeds within your own state, either at a dispensary or through a specific seed company’s website.
How to buy cannabis seeds online
Before you purchase seeds online, you’ll need to figure out what strain you want to grow and what breeder you want to buy from.
Because US federal law still prohibits cannabis, it can be hard to find information on seed banks and breeders. Breeders who have a long history and positive reputation are usually a good place to start. To get an idea of what well-established breeders look like, check out:
- Sensi Seeds
- DNA Genetics
- Green House Seeds
- Southern Humboldt Seed Collective
- Exotic Genetix
You can also do some research and find an online grow journal that details the whole growing process of a specific strain from a particular breeder. Through these, you’ll be able to look over another grower’s specific notes and see pictures of the final results.
If you grow some seeds and like the results, try growing another strain from that same breeder and see how it goes.
How to buy cannabis seeds at a dispensary
Although this option is only available to people living in states with medical and adult-use legalization, buying marijuana seeds at the dispensary is far more straightforward. However, your options are more limited.
Dispensary staff should be able to give you information on the seeds they’re selling, but keep in mind that a lot of dispensaries focus on selling flower and end-products. It’s a good idea to call ahead and talk to staff to see if they are knowledgeable about seeds and can give you specific information on growing.
How to look for quality genetics when buying marijuana seeds
Breeders talk about “unstable genetics,” meaning that a seed’s origin is unknown. Make sure that when you buy a packet of seeds that it or the breeder who produced them can list where the seeds came from and how they were crossed and/or backcrossed to get the seed that you hold in your hand. If you can’t get a seed’s history, it could be anything and the result of poor breeding practices.
An inexperienced breeder might cross a male and a female one time and sell the resulting seeds as a new hybrid strain, but professional breeders usually put their strains through several rounds of backcrossing to stabilize the genetics and ensure consistent plants that reflect those genetics.
Which strain should I grow?
Even one weed plant can produce a lot of buds come harvest time, so make sure you grow a strain you like. Note strains you enjoy when you pick something up at the dispensary or smoke with friends, and look for seeds of it when you want to start growing.
Some strains are easier to grow than others because they are more resistant to mold and pests, so if you’re new to growing, you may want to try an easier strain to start.
Some strains also take longer to grow than others. Depending on whether you’re growing indoors or outdoors, you may want to grow a quicker marijuana strain if you live in a climate that get cold and wet early in the season. For example, indicas are known for having a shorter flowering time than sativas.
All of this information should be available to you when buying quality seeds.
What’s the difference between regular, feminized, and autoflower seeds?
If you buy a packet of regular seeds, they’ll come with a mix of males and females. A lot of cultivators prefer to grow these because they haven’t been backcrossed—essentially inbred—as much as feminized or autoflower seeds. You’ll need to sex out the seeds once their reproductive organs show during the flowering phase and discard the males—because they don’t produce buds and will pollenate females, resulting in seeded flowers.
Seeds can come feminized, meaning you can just put them in soil and start growing for buds. These seeds are guaranteed to be bud-producing females and growing them cuts out the step of having to sex out plants and discard the males.
It also reduces the risk of having a stray male sneak into your crop—just one male can pollinate a huge crop, causing your females to focus their energies on producing seeds instead of buds.
Autoflower plants change from the vegetative to flowering state with age, not the changing of their light cycle. They have a short grow-to-harvest time and can be ready to harvest in as little as 2 ½ to 3 months from when you put the seeds in the ground. The downside is that, typically, they are less potent, but autoflower seeds are great for people who want to grow cannabis but don’t want to spend a lot of time doing it.
How much do marijuana seeds cost?
Cannabis seeds usually come in a pack of 10 or 12 seeds and start at around $40 a pack and go up from there. Some high-end genetics can run between $200 to $500 a pack.
Feminized and autoflower seeds will cost more because more breeding work was put in to creating them and they take less time for the grower to get buds.
How many seeds should I buy? Are they all going to survive?
When you grow any amount of seeds, a percentage of them won’t germinate, even if you get them from a reputable breeder. Always count on a few not germinating or dying off, or roughly 1/4 of the total you put in the ground.
When growing regular seeds, some won’t germinate and some will have to be discarded because they’ll turn out to be males. With feminized seeds, some won’t germinate, but a higher percentage of them will turn into flowering plants because there won’t be any males.
If you want six total cannabis plants to harvest for buds and are growing from regular seeds, start with about 4 times as many, or 24 seeds. Some won’t germinate and some will turn out to be males, and then you’ll want to discard down to the six best phenotypes. If growing feminized seeds, you can probably start with about twice as many seeds in this case (about 12); a couple won’t germinate, and then discard down to the six best phenotypes.
Make sure to always stay within your state’s legal limit of growing plants.
How do I buy strain-specific cannabis seeds?
Strains like Blue Dream, Gelato, and Original Glue have gained in popularity in recent years. Check out these resources on how to buy these types of cannabis seeds:

An Introduction to the Big Business of Cannabis Seeds

Cannabis seeds are, obviously, integral to the weed industry. With so many growers around the world, they’re in higher demand than ever. As a result, a network of online and physical retailers has popped up to satisfy both legal and grey market needs.
But increased demand and legalization are changing the seed business. How will the cannabis seeds market evolve with growing demand and more legalization efforts?
The 3 main typles of cannabis seeds.
There is a great deal of variety within cannabis seeds. Specifically, you can divide them into three main types:
Regular: These contain both male and female plants, meaning that half of the plants will not flower. This kind requires more light to begin flowering.
Autoflower: Autoflowering seeds begin flowering as soon as the plant reaches maturity.
Feminized: Seeds that only produce the flowering part of the cannabis plant i.e. the female part.
Aside from the type of seed, seeds differ genetically. This means that breeders have grown them into distinct stains that can produce a wide variety of effects. This is where the real value in cannabis seeds lies.
Why genetics matter.
Anyone who has ever consumed cannabis in any of its forms knows that strain matters. This goes beyond sativa vs. indica. Strains can be bred to produce a variety of effects and serve purposes that go way beyond flavor. For example:
High-CBD hemp seeds are ideal for creating potent cannabis oil.
Strains can be bred for pain management and other medical purposes.
Plants can be genetically altered for shorter, better yields.
Specific types of hemp create stronger, longer lasting fiber.
Not only is the ability to create products with distinct terpene flavor profile a great way to appeal to consumers, but the right genetics can produce vastly different effects with medical and economic advantages. And the more the medical and recreational markets grow, the more demanding consumers are of their weed products and the more competition there is when starting a cannabis dispensary or another type of business.
Who sells cannabis seeds.
Anyone can sell cannabis seeds but not all vendors are legal. International drug laws do not strictly regulate cannabis seeds because they have a variety of uses — animal feed, oil production, clothing material — but some countries are stricter about their importation than others.
Like the sale of growing equipment, cannabis seeds are adjacent to the weed industry but not strictly apart of it. This makes controlling or even studying the market difficult.
Different types of vendors.
According to one scientific paper published by the United Nations Office on Drugs and Crime, there are three different components to this business:
1. Seed companies: Seed companies produce the seeds. The majority are based on the Netherlands or Spain due to their more lenient laws. There are around 122 large scale seed companies in Europe, according to the UN’s research.
2. Breeders: Breeder cross-breed strains to create new ones. They can work for seed companies or conduct their own experimentation.
3. Resellers: There are many more resellers than either of the above two categories. Resellers will often sell product from a variety of companies and can inhabit a legal grey area, catering to black market weed vendors as well.
Marijuana law remains hazy. Today, an increasing number of companies are patenting weed technology, seeds, and the hottest cannabis products. But whether those patents are enforceable, and where they are enforceable within the U.S., remains to be seen.
Plant breeders’ rights
Since the 1960s, plant breeders can have exclusive control over a new variety of a plant they create for twenty years following a submission to the plant variety office. Control over everything from seeds to cuttings is given to that breeder for that period of time if that office decides that their plant is genetically or physically distinct. As a result, plant breeders’ can technically have unique rights to the cannabis seeds they breed.
In the U.S., you can also patent genetic varieties of any plant. This includes cannabis seeds. Though the U.S. Patent and Trademark Office is federal, it operates independently of other government agencies. This means that you can patent weed strains, and many companies have done so already.
However, even if someone does rightfully own a patent of a certain type of seed, that doesn’t mean that their patent is enforceable nationwide.
According to the United States Patent and Trademark Office, you can patent asexually reproduced plants if they possess certain characteristics due to their genetics or if they’re a hybrid version of a different plant. According to one Reuters report, 39 cannabinoid-related patents were filed in 2018. Cannabinoids are the compounds found in weed that vary from strain-to-strain.
The vast majority of these patents went to drug companies. A few went to universities and other entities.
Another industry that will boom post-legalization.
Cannabis law is still under development. However, entrepreneurs and big companies alike are increasingly patenting a major element that can set their product apart from the rest: cannabis seeds. With the rights to a signature strain, there are two things that can be done:
Sell them over the internet or in stores to the increasing number of growers and individuals looking to produce their own weed
Today, people all over the internet are selling cannabis seeds with little to no oversight but, seemingly in anticipation of legalization, corporations are striving to control everything from plant genetics to technology. This could help certain ahead of their time companies could control major industries like CBD — all thanks to seed patents they’ve filed today.
Cannabis seeds can produce widely different plants. And in anticipation of national legalization, the market is evolving quietly, but quickly.
