How to start growing marijuana plants?
You can start growing marijuana plants from one of two primary sources; either from clone or from seed – both methods have their pros and cons.
What are marijuana clones?
Generally, commercial cannabis producers will plant thousands of seeds of one strain and choose the best plant or “phenotype.” They will then stabilize the pheno over many generations to produce a commercially viable cultivar. This process is often called “phenofinding” or “strain hunting” by both professionals and hobbyists alike. Cuttings (or cannabis clones) will be taken from that individual cannabis plant, enabling consistent genetics for mass production (think of a McDonalds’ Cheeseburger – these are exactly the same across the globe).
For the typical homegrower, it’s much easier from a practical and logistical perspective to use seeds rather than clones. It makes more sense financially and will usually produce better overall results. Stronger cannabis plants, less prone to disease.
Why grow weed from seed?
In nature, marijuana seeds, like human beings, contain the combined genetic information of both parents, expressing different parental traits and often new, surprising traits that both parents lack. This constant recombination of genes is the cornerstone of evolution. The cannabis seeds purchased from a reputable seed bank are specially selected offspring, stabilized for uniformity but still subject to the laws of nature. Your Homegrown seeds will produce very similar plants, but can still throw up some interesting and exciting phenos.
Growing from a good stock of pot seeds will usually produce a stronger cannabis plant with higher quality genetics and, importantly, will likely produce bigger yields of better cannabis.

Best place to buy marijuana seeds online USA
While weed seeds for sale are now much easier to find than ever before, you should remain vigilant, careful and open-eyed. All is often not what it seems. Many claim to be the best seed banks or the best place to buy marijuana seeds online in the USA, but few actually offer stable genetics. There are some sites that claim to be american seed banks, but are actually European.
These cannabis seed banks online ship from Europe, and you can find that your seeds will take many, many weeks to arrive, if they arrive at all! Besides the reduced chance of a successful delivery, international shipments are exceptionally bad for seeds, for a number of reasons. These range from temperature fluctuations in transit to actual physical damage. Reduce your risk – make sure you’re buying cannabis seeds USA.

Am I getting quality genetics from my cannabis seeds?
If you’re searching the internet for information, watching marijuana youtube channels, visiting marijuana growing forums or looking at other types of media, you’ll likely have heard marijuana breeders talk about “unstable genetics.” This typically means that a cannabis strains origin is unknown, or that the lineage of that seed or strain is of poor genetic quality (often from rushing production, sacrificing the diligent testing of responsible online cannabis seed banks).
Best quality marijuana seeds
Our breeding partners possess state-of-the-art facilities in North America, South America and Europe. With one of the oldest collections of original mothers in the world and proven, stable hybrids, Homegrown offers the best quality marijuana seeds for sale and the largest collection of stable marijuana strains in seed form anywhere in the world. Our library is so extensive, we also produce seeds for many of the most reputable companies on the internet – we won’t name names before you ask!
Make sure when you buy your marijuanaseed online that the brand, the marijuana seed bank or the breeder who produced them can provide details on where the seeds came from (the lineage) and how they were crossed and/or backcrossed. If you cannot gain access to a seed’s history it could be literally anything and the result of poor breeding practices. That won’t give you the best chance of producing a quality, Homegrown crop.
It’s not unusual for an unprofessional or inexperienced breeder to simply cross a male and a female and sell the resulting seeds as a new hybrid strain. In contrast, professional breeders, breeding programs and the best seed banks will put their strains through several generations of backcrossing to stabilize the genetics, ensuring consistent plants that reflect those genetics.
At Homegrown, we do just this. We guarantee you ALWAYS receive marijuana strains you’ll be delighted with. We’ve partnered with the best so you can be sure of one thing – our credibility!
How do marijuana laws affect buying pot seeds?
The law is obviously an important thing to consider before looking for pot seeds for sale or searching for the best place to buy marijuana seeds. You should certainly check the laws in your area regarding which types of cannabis or marijuana products you’re allowed to purchase, as well as any laws about growing weed from seed at home.
The legal status of cannabis products and home-growing marijuana will dictate where and how you buy weed seeds online. If you live in a state where it is legal to grow weed at home and there are not that many restrictions on home growing, you’ll likely be able to buy cannabis directly from your favorite licensed dispensary. In some cases, you may even have the option of buying from a brick-and-mortar retailer or an online retailer. As mentioned earlier, there are weed seed banks that exist outside of the US, and will sell seeds for “souvenir purposes” only. Do note, however, it is technically illegal to bring seeds into the US and Customs will very likely seize any pot seeds that they find in the mail or on an individual opening that mail.
For most Americans, ordering from overseas is not a sensible way of buying marijuana seeds online. Companies that use these tactics to sell seeds online will not be able to legally provide information on the product itself, the genesis of the product, or help you in the event things don’t work out perfectly. These are all things that we consider to be vitally important to our Homegrown customers. While we offer seeds for sale and allow you to order seeds online, our core philosophy at Homegrown Cannabis Co is that we sell expectation. We aim to deliver.
Growing marijuana plants? Make Sure You Plan Ahead.
Whichever way you choose to go about buying your weed seeds, you need to plan ahead before growing marijuana. Here are some of the most important things you’ll need to consider, to ensure your marijuana seed purchase will meet your needs, objectives and, most importantly, your expectations.
How many seeds should I buy? Are they all going to survive?
Irrespective of the cannabis strain you buy, or whether you buy that strain as regular seeds, feminized cannabis seeds, or autoflowering seeds, you should consider how many marijuana plants you’ll want to grow. It’s a great idea, and a good moment, to recheck your local area laws and identify the number of plants you’re legally allowed to grow.
Nature is nature. No matter the stability of the genetics or the quality of a strain, you should always plan on a certain percentage of your feminized seeds failing to germinate, or, and this is far less likely, producing less than perfect plants. Genetic diversity is the foundation of evolution, but you’re far more likely to have a happy surprise than an unpleasant one.
Marijuana seeds have a natural viability rate between 90% and 100%. This is natural selection. You are very, very likely to enjoy a 100% germination rate with your Homegrown weed seeds, but it’s not uncommon to experience a 10% fail rate, or to have a seedling fail. It’s disappointing, sure, but it’s part of life.
Understanding this, you should plan on purchasing more seeds than you think you’ll need from your chosen marijuana seed co. For example, if you want to grow 4 plants, we’d recommend purchasing an 8 pack, if you want to grow 8 plants, we’d recommend a 12 pack. As a general guideline, assume that at least 10% of the seeds you plant will, for one reason or another, not make it to harvest. We’d recommend purchasing up to 2 times the number of seeds. Correctly stored cannabis seeds will last for many years, they won’t go to waste.
If you wish to purchase regular seeds (seeds that will produce, on average, equal numbers of male and female cannabis plants) you need to plan for the males. While the average numbers are 50/50, you could end up with a 100% male or 100% female crop.
A good guide for regular seeds is to purchase up to 4 times the number of female plants you wish to grow. If you want six cannabis plants to harvest for buds and are growing from regular seeds, consider buying up to 24 regular cannabis seeds. Some might not germinate, some will turn out to be male cannabis plants and you’ll want to choose the six best phenotypes from what remains.
The short version here is that, for best results and to ensure minimal frustrations, buy and plant more seeds than the number of mature plants you want to produce. We know that this can put more financial pressure on the beginner grower, but the good news is you can find more than 20 strains in the cheap weed seeds section with our amazing BOGOs.
Where do you want to grow? Indoor or Outdoor?
You’ll need to decide if you will be cultivating your cannabis garden inside or outside. Growing cannabis indoors gives you considerable flexibility, as you’ll be able to control and fine-tune the local environment for your specific plants or strains. This gives you more freedom in terms of which kind of seeds you decide to buy. On the other hand, if you plan on growing outdoors, you’ll likely be well-served spending a little more time looking at the specific traits of the seeds you want to purchase, to ensure they will perform positively in your environment and climate.
Growing marijuana outdoors
The first quarter – or certainly the months of January and February – of the year is the perfect time to start planning your outdoor marijuana garden, to get a head start on the outdoor growing season. To take advantage of the perfect growing conditions, you’ll likely be running an outdoor grow from a given point sometime between March and November although exactly when will be dictated by your geographical location.
You can find a selection of our best outdoor strains right here, and you should definitely check out the recommended strains from our master outdoor growers, Swami and Nikki from Swami Select. Cannabis seeds California style!
Growing marijuana indoors
For indoor grows, the outdoor or ambient conditions obviously play a far lesser part in the decision – the time of year is rarely a big factor for the smaller home grower. Your time is best invested in planning where to locate your indoor marijuana grow and choosing the most appropriate cannabis growing equipment you can find, based on the specifics of your grow area and your budget. Using the best equipment to grow your own marijuana can have dramatic results on the cost of production and can be the difference between a successful and unsuccessful harvest.
Check out our best indoor strains here or take a look at the favourite strains of our indoor guru, Kyle Kushman.
Indica, sativa, or hybrid
There is a seemingly endless – yet still growing – variety of marijuana strains available today. The beauty of breeding is that it’s always possible to create something new, even if the differences are subtle or nuanced. Before buying marijuana seeds, you’ll want to be clear on what kind of pot you want to end up with, and this is often determined by the kind of broad, overall effect you want or need.
Indica seeds or indica strains are more likely to deliver physical, bodily effects. They’re often linked to relaxation, sedation or managing pain. Most marijuana products marketed as sleep-aids are indica-dominant. Sativa seeds or sativa strains are usually linked with a more cerebral or mental high that can increase energy, provide a buzzy high and / or are generally mentally stimulating. Hybrid strains, as the name suggests are a mix of both Indica and Sativa traits and will produce a variety of effects, depending on the specific parent strains used to create the hybrid.
Which strain do you want to grow?
Having made a broad choice on the type of cannabis you want to cultivate, you should consider some strain specifics beyond the three general categories of indica, sativa or hybrid. If you are not totally sure which strain you want to grow, or you’re curious to learn about other strains you might not be familiar with, browse through the online catalogs of reputable seed banks and read about the various strains currently available.
A good place to begin narrowing down your ideal strain selection would be to consider some or all of the following.
What is the potency of the strain? If you’re looking to buy seeds to grow a potent plant, you should ask if the strain tends to produce plants with high THC levels or high CBD levels. Usually there is a trade-off between the two.
Are you looking for very productive, mature marijjuana plants? High yield strains can be a great choice but remember: the amount of room required to house them is more than normal. That can be especially important for an indoor grow.
Are you a beginner? If so, you may want to consider autoflowering strains. You don’t need to be an expert to grow autoflowers and we have a huge range – you can browse autoflower seeds usa here. On the other hand, more experienced cultivators may prefer to stick with time-served photoperiod cannabis strains.
Do you want seeds better suited for medical marijuana or recreational marijuana? We have an excellent selection of high cbd seeds available, ideal for medicinal cannabis.
You can also consider other factors such as flavor and aroma, specific desirable effects and budget.
When you’ve decided which strain you want to grow, be sure to do a bit of research to familiarize yourself with the unique growing needs and specifications of that strain. While there are general guidelines for growing any type of cannabis, different strains also have their own specific needs. Similarly, some strains do better in specific parts of the world or climates. You should grow a strain that is well-suited to the growing environment you’ll be creating for your plants.
How much do weed seeds cost?
Cannabis seeds for sale USA historically come in packs of 5, 10 or sometimes 12 – in the case of regular pot seeds. At Homegrown, we researched, spoke with and listened to customer feedback and we offer our seeds in packs of 4, 8 and 12 (24 seed packs are also available). This more accurately represents the most typical homegrown garden sizes in legal marijuana states. For customers requiring larger orders, we also operate a designated wholesale department.
We offer retail seeds from as little $7.00 per seed, and we offer free delivery on larger packs. Smaller pack sizes cost a little more per seed. Typically the standard 12 packs cost around $10 per seed while some of more high-end genetics can run to around $12 per seed.
Feminized and autoflower seeds will generally cost more, but this reflects the extensive research and development required to create them. Buy cannabis seeds online USA here.
Note: If you are actively using the internet for research purposes, you should be aware that many publications and information repositories frequently mis-spell some of the more common terms you may want to use. Here are some of the more popular incorrect searchable terms you may want to use in your information gathering: canabis seeds, cannibis seeds, marajuana seeds, canibus seeds, cannibus seeds, canabus seeds, marijauna seed, marihuana seeds, and marijuna seeds.
How to Legally Purchase Cannabis Seeds in the United States
Thinking about starting your own cannabusiness? You are not alone. From CBD to medical marijuana to edibles, legal cannabis has become one of the fastest-growing industries in the United States, with few signs of slowing down any time soon.
If your business will include cannabis growing or cultivation, then you are probably wondering how to get your hands on weed seeds. legally. Before taking that step, though, make sure your business has the necessary license to operate legally in your state.
First and Foremost: Know Your State Laws
State law governs if and how you can operate your cannabis growing business, and each state takes a slightly different approach. Your state may offer a large number of permits with few prerequisites, a small number of permits with an extensive application process, or something in between.
Here are a couple of other factors to keep in mind about the legality of cannabis seeds:
- State law treats growing marijuana for selling purposes differently from growing marijuana for personal use. Your state may allow you to grow a limited number of cannabis plants for personal use without a license. For example, Colorado residents over age 21 can grow up to six plants, with as many as three plants flowering at one time.
- Cannabis seeds can often be purchased legally for uses other than growing marijuana such as fishing bait, bird food, and preservation. The government recognizes that cannabis seeds have other uses beyond just growing more marijuana.
In addition to studying your state’s regulations, you should also join local cannabusiness groups and meet with a local cannabis business attorney for assistance. There is no such thing as going into the marijuana business too prepared. Once you are ready to take the step of legally buying cannabis seeds, you have a few options to choose from.
It’s Best to Shop Local, but Buying Online Is an Option
If you live in a state that permits the sale of marijuana seeds, your best bet is to shop locally for high-quality seeds. This means visiting a dispensary, local farmers market, or seed company in your state to make your purchase. There, you can get the in-person help you need to make your purchase legally.
It is also an option to buy cannabis seeds online from an online seed bank and then have the seeds shipped to you, so long as you are abiding by state law. The risk here is that your package could still be confiscated. While it is unlikely that you would face criminal charges, there is no guarantee because of the way federal law treats marijuana products.
Can I Buy Cannabis Seeds in Other States or Countries?
You shouldn’t have any trouble buying cannabis seeds in another state or country if it’s legal there. It’s bringing the seeds back to your home state that can get you into trouble.
In the United States, cannabis seeds cannot cross state lines because marijuana products are still illegal under federal law. Though rare, transporting the products across state lines could result in federal criminal charges. This is true even if you are purchasing cannabis seeds in a state that authorizes it and entering a state that also authorizes it.
The same is true for buying cannabis seeds in another country. It may sound like a great idea to buy cannabis seeds while visiting one of the world-renowned marijuana seed banks that exist in places such as the Netherlands or the United Kingdom. But when you re-enter the U.S. with your goods, Customs and Border Protection will seize any seeds they find, even if your plane landed in a state where they are legal. Again, it goes back to marijuana being illegal under federal law.
How Much Do Cannabis Seeds Cost?
How much you will pay for cannabis seeds depends on the strain of marijuana you buy. Typically, a pack of 10 or 12 seeds starts at around $40. You can expect to pay up to $500 for high-end strains. Again, it is important to only buy cannabis seeds from a legal and reputable seed bank or dispensary — and only if you know you are abiding by state law.
Legal Help for Cannabusiness Entrepreneurs
Cannabis law is an ever-evolving tangle of state and federal regulations that often contradict one another. Additionally, the cannabis industry is very new, and still illegal under federal law. For these reasons, it’s important to seek the advice of a business attorney well-versed in cannabis law so that your venture starts out on the right track and you avoid legal problems.
Cannabis seeds 101: How to grow marijuana from seed
Cannabis is grown from one of two sources: a seed or a clone. Seeds carry genetic information from two parent plants and can express many different combinations of traits: some from the mother, some from the father, and some traits from both.
In commercial cannabis production, generally, growers will plant many seeds of one strain and choose the best plant. They will then take clones from that individual plant, which allows for consistent genetics for mass production.
If cannabis is legal in your state, you can buy seeds or clones from a local dispensary, or online through various seed banks.
How to grow cannabis from seed
Cannabis has four main stages of growth:
- Germination—when a cannabis seed first sprouts out of the ground and grows its taproot down into the soil.
- Seedling—when a seed develops into a baby plant; it’s delicate in this stage, with only a few leaves, and is sensitive to heat and humidity.
- Vegetative—these are juvenile plants that grow quickly, adding lots of plant mass in the form of stems, branches, and fan leaves.
- Flowering—these are mature plants that start to produce buds that will eventually be harvested and consumed.
What do cannabis seeds look like?
Cannabis seeds are about the size of a BB, or about ⅛ – ¼” in diameter. They often have lines on them, as in the image above, called “tiger stripes.”
Cannabis seeds vs. clones
For the typical homegrower, it may be easier to obtain cannabis seeds rather than clones. Growing from seed can produce a stronger plant with more solid genetics.
Plants grown from seed can be more hearty as young plants when compared to clones, mainly because seeds have a strong taproot. You can plant seeds directly into an outdoor garden in early spring, even in cool, wet climates.
If growing outside, some growers prefer to germinate seeds inside because they are delicate in the beginning stages of growth. Indoors, you can give weed seedlings supplemental light to help them along, and then transplant them outside when big enough.
Most seeds that you will buy are regular seeds as described above, but here are a couple more types.
How weed seeds work
Cannabis can be either male or female—also called “dioecious”—but only females produce the buds we all know and love. For reproduction, males have pollen sacs and pollinate females, causing female flowers to produce seeds.
Once cannabis seeds are mature, the female plant begins to die, and seeds are either dropped to the ground where they grow into new cannabis plants next spring, or the seeds are harvested for processing into seed oil or food products, or stored so they can be sown in the ground later and become the next generation of plants.
To get the buds found in medical and recreational stores, female cannabis plants are grown in an environment without males—or the males are removed from the area before they release pollen—so the females don’t create seeds. Females can then focus their energies on producing buds and not seeds—this high-potency marijuana is traditionally known as “sinsemilla,” meaning “seedless.”
Some varieties of cannabis can produce male parts alongside female flowers on the same plant, especially if exposed to environmental stressors. These plants are known as hermaphrodites, and sometimes they can self-pollinate to create seeds.
Pros and cons of using cannabis seeds
Check out Johanna’s full video series on how to grow weed on Leafly’s YouTube .
If buying from a reputable breeder or seed bank, growing from seed is the best way to ensure your plants will have solid genetics and start clean, meaning they won’t come with diseases or pests.
Also, buying from a reputable breeder or seed bank will give you a sense of what a particular strain will look and smell like, how it will grow, and how much it will yield at harvest.
The main drawback to growing from seed is there is no guarantee as to what you’ll end up with—if you buy a regular pack of cannabis seeds, it will be a mix of males and females. You’ll need to sex them out (more below) to identify the males and get rid of them, because you don’t want your females producing seeds.
Sexing marijuana plants can be a time-consuming process, and if you don’t catch males, there is a risk that even one males can pollinate your entire crop, causing all of your female weed plants to produce seeds.
One way to avoid sexing plants is to buy feminized seeds (more below), which ensures every seed you plant will be a bud-producing female.
You can also minimize headaches and avoid the hassle of seed germination and sexing plants by starting with clones.
How weed clones work
Aside from producing cannabis through seeds, or sexual reproduction, you can also reproduce the plant through cloning, or asexual reproduction. A clone is a cutting that is genetically identical to the plant it was taken from—that plant is known as the “mother.”
Pros and cons of using cannabis clones
Through cloning, you can create a new harvest with exact replicas of your favorite plant. Because genetics are identical, a clone will give you a plant with the same characteristics as the mother, such as flavor, cannabinoid profile, yield, grow time, etc. So if you come across a specific strain or phenotype you really like, you might want to clone it to reproduce more buds that have the same effects and characteristics.
With cloning, you don’t have to get new seeds every time you want to grow another plant—you just take a cutting of the old plant—and you don’t have to germinate seeds or sex them out and get rid of the males.
One drawback of clones is they need to be taken during the vegetative stage of a plant—flower is too late—so if you have a small setup with only one light, it can be hard to keep clones alive while flowering other plants, because the two need different amounts of light.
Another drawback to clones is they can take on negative traits from the mother plant as well. If the mother has a disease, attracts pests, or grows weak branches, its clones will probably have the same issues.
Additionally, every long-time grower will tell you that clones degrade over time.
What are feminized cannabis seeds?
Feminized cannabis seeds will produce only female plants for getting buds, so there is no need to remove males or worry about female plants getting pollinated. Feminized seeds are produced by causing the monoecious condition in a female cannabis plant—the resulting seeds are nearly identical to the self-pollinated female parent, as only one set of genes is present.
This is sometimes referred to as “cloning by seed” and will not produce any male plants. This is achieved through several methods:
- By spraying the plant with a solution of colloidal silver, a liquid containing tiny particles of silver
- Through a method known as rodelization, in which a female plant pushed past maturity can pollinate another female
- Spraying seeds with gibberellic acid, a hormone that triggers germination (this is much less common)
Most experienced or commercial growers will not use feminized seeds because they only contain one set of genes, and these should never be used for breeding purposes. However, a lot of beginning growers start with feminized seeds because they eliminate the worry of having to deal with male plants.
Top feminized cannabis strain families
A lot of classic weed strains that have been around for a while come in feminized form. Some popular fem seeds are:
What are autoflowering cannabis seeds?
Autoflowering seeds are also popular with beginning growers. They are easy to grow because you don’t have to worry about light cycles and how much light a plant receives.
Most cannabis plants begin flowering when the amount of light they receive on a daily basis reduces. Outdoors, this happens when the sun starts setting earlier in the day as the season turns from summer to autumn. Indoor growers can control when a plant flowers by reducing the daily amount of light plants receive from 18 hours to 12 hours.
However, a type of cannabis called Cannabis ruderalis, which developed in extreme northern conditions without much sunlight, will begin flowering once the plant reaches a certain age—they automatically start flowering regardless of the amount of light they receive, hence the name “autoflower.”
Pros and cons of growing autoflower
Because they grow and flower quicker, growers can fit in multiple autoflower cannabis harvests into the span of one regular harvest.
Autoflowers can be started in early spring and will flower during the longest days of summer, taking advantage of high quality light to get bigger yields. Or, if you get a late start in the growing season, you can start autoflowers in May or June and harvest in the fall.
Also, autoflower plants are small—perfect for closet grows or any small grow, or growing outdoors where you don’t want your neighbors to see what you’re up to.
A couple big drawbacks, though: Autoflower strains are known for being less potent. Also, because they are small in stature, they usually don’t produce big yields.
However, potency in autoflowering varieties has increased significantly since their initial introduction, with some breeders crossbreeding the low-THC ruderalis with other more potent varieties.
Tips for growing autoflower marijuana seeds
Autoflowering strains require some preparation, as they will grow quickly and start to flower whether or not you’re ready for them.
Many marijuana growers start autoflowers early in the season, and at a different time than a regular crop, so keep the season and climate in mind when growing and harvesting—your plants still need warmth to grow, and rain can give them bud rot. Consider growing in a greenhouse to protect them.
Training cannabis plants
Because training happens during vegetative growth, for autoflowering plants, this period could be as short as a few weeks, which means time is limited. Try topping your autoflowers after they have three nodes, and stop once they begin to flower. You will want to prune them lightly.
Go easy on nutrients
Autoflowers don’t need lots of nutrients because they’re small and don’t spend much time in the vegetative cycle. They won’t need as much veg nutrients—such as nitrogen—but will need more bloom nutrients.
What are high-CBD cannabis seeds?
CBD, or cannabidiol, is one of the chemical components—known collectively as cannabinoids—found in the cannabis plant. Over the years, humans have selected plants for high-THC content, making cannabis with high levels of CBD rare. The genetic pathways through which THC is synthesized by the plant are different than those for CBD production.
Cannabis used for hemp production has been selected for other traits, including a low THC content, so as to comply with the 2018 Farm Bill. Consequently, many varieties of hemp produce significant quantities of CBD.
As interest in CBD as a medicine has grown, many breeders have crossed high-CBD hemp with cannabis. These strains have little or no THC, 1:1 ratios of THC and CBD, or some have a high-THC content along with significant amounts of CBD (3% or more).
Seeds for these varieties are now widely available online and through dispensaries. It should be noted, however, that any plant grown from these seeds is not guaranteed to produce high levels of CBD, as it takes many years to create a seed line that produces consistent results. A grower looking to produce cannabis with a certain THC to CBD ratio will need to grow from a tested and proven clone or seed.
How to germinate marijuana seeds
Germination is the process in which a seed sprouts and begins to grow into a new plant. Also referred to as “popping,” germination is the very first step in starting your weed grow.
Marijuana seeds can be acquired from an array of sources and can vary in quality. For more info on how to buy marijuana seeds, check out our Guide to buying cannabis seeds.
Cannabis seeds require three things to germinate: water, heat, and air. There are many methods to germinate seeds, but for the most common and simplest method, you will need:
- Two clean plates
- Four paper towels
- Distilled water
Take four sheets of paper towels and soak them with distilled water. The towels should be soaked but shouldn’t have excess water running off.
Take two of the paper towels and place them on a plate. Then, place the marijuana seeds at least an inch apart from each other and cover them with the remaining two water-soaked paper towels.
To create a dark, protected space, take another plate and flip it over to cover the seeds, like a dome.
Make sure the area the seeds are in is warm, somewhere between 70-85°F.
After completing these steps, it’s time to wait. Check the paper towels once a day to make sure they’re still saturated, and if they are losing moisture, apply more water to keep the seeds happy.
Some seeds germinate very rapidly while others can take a while, but generally, seeds should germinate in 3-10 days. If it’s been two weeks and a seed hasn’t sprouted, it’s probably a dud and won’t sprout.
A seed has germinated once the seed splits and a single sprout appears. The sprout is the taproot, which will become the main stem of the plant, and seeing it is a sign of successful germination.
It’s important to keep the delicate seed sterile, so don’t touch the seed or taproot as it begins to split.
Transplanting germinated cannabis seeds
Once you see the taproot, it’s time to transfer your germinated seed into its growing medium, such as soil.
- Fill a 4-inch or one-gallon pot with loose, airy potting soil
- Water the soil before you put the seed in; it should be wet but not drenched
- Poke a hole in the soil with a pen or pencil—the rule of thumb is: make the hole twice as deep as the seed is wide
- Using a pair of tweezers, gently place the seed in the hole with the taproot facing down
- Lightly cover it with soil
Keep a close eye on the temperature and moisture level of the soil to keep the seed happy. It’s very delicate at this stage. Use a spray bottle to water it—over-watering can suffocate and kill the delicate sprout.
Within a week or so you should see a seedling begin to grow from the soil.
Germinating cannabis seeds doesn’t always go as planned. Some seeds will be duds. Others will be slow and take longer to sprout. But some will pop quickly and grow rapidly.
This is the beauty of seeds—often, you can tell which plants or genetics will thrive right from the get-go. This will help you determine which plants you want to take cuttings from for clones or for breeding if you want to create a seed bank of your own.
How to sex a pot plant

As we’ve mentioned, cannabis is a dioecious plant, meaning male and female reproductive organs appear on different plants.
Because only female cannabis plants produce buds and you want them to focus all their energy on producing buds and not seeds, it’s important to identify and get rid of male weed plants so they don’t pollinate females. If females are pollinated, it will give you buds filled with seeds, making your weed harsh and unpleasant.
Cultivating males is important for breeders trying to cross new strains and genetics, but most people growing for buds will want to remove the males.
As mentioned above, you can skip the processing of sexing weed plants by growing with feminized seeds or clones.
If growing male and female cannabis seeds, they’ll start to show their sex organs, or “pre-flowers,” after 8-10 weeks from germination.
Cannabis plant sex organs appear on nodes, the points where branches grow off from the main stalk.
Males will have round balls—these will develop into pollen sacs, which will release pollen into the air when mature.
Females will have a round structure with long hairs—these hairs will develop into pistils, which will catch pollen in the air.
Pre-flowers can initially be extremely small and hard to identify with the naked eye, but you can use a magnifying glass to get a better look.
Can I grow a seed I found in a bag of weed?
Finding a cannabis seed in your stash is not ideal, but we’ve all been there before. Although much less common than it once was, it still happens. Sometimes you’ll notice one when grinding down some flower, or you’ll see one pop, spark, and crackle from the heat of a lit bowl.
These are referred to as “bagseeds” and whether or not you can grow one will depend on where it came from.
Is a bagseed good or bad?
Seeds found in finished cannabis buds can develop for a number of reasons. For example, a male plant may have accidentally pollinated a flowering female during the growing process. But more commonly, they’re a sign of stress and can be attributed to high temperatures during the final stages of flowering or an exaggerated spike in climate or environment.
Seeds can also form in plants with genetic disorders or instability, like hermaphrodites—plants that develop both male and female reproductive parts. Generally, stress and genetic disorders are viewed as bad, so temper expectations with any plant you start from a bagseed.
But sometimes you get lucky and find a mature seed in some really nice herb. Strains like the legendary Chemdog wouldn’t be possible without adventurous smokers planting and proliferating the seeds they found in a bag of kind bud.
So don’t discount bud because it has a seed or two in it. While not ideal, it could be the origins of the next great weed strain.
Ask yourself a few questions to decide if it’s worth the time and energy to grow the seed.
Was the seed found in good weed?
If you don’t like the flavor, effects, or even the look of the bud, then it’s probably not worth growing.
Are you ready to grow?
Growing marijuana takes a certain level of commitment: time, energy, and financial resources, so be sure you can commit to the whole process.
Is the seed viable?
For a seed to be viable, it must be mature enough to have a completely formed genetic blueprint, and it must be strong enough to germinate and pop through its hard casing and sprout its crucial taproot.
There are a few indicators that will give you a sense of whether the seed is worth germinating.
- Tiger stripes—dark stripes on the seed which resemble veins on a leaf are generally good
- Solid shell—a seed should be able to withstand a little pressure when pinched between your fingers; if it crumbles or cracks, it’s no good
Immature seeds tend to be light in color and have a soft outer shell.
In some cases, even if a seed isn’t completely mature, there’s still a chance it could be viable. But often these are extremely weak, take long to develop, and express other unfavorable characteristics. Growers usually discard weak plants to free up space.
You might also find a mature seed that has been physically damaged through poor handling, like rough trimming. In those cases, it probably isn’t worth the effort to try and germinate the seed.
But if the seed you found looks decent, you might as well germinate it and see what sprouts.
Time to germinate
Viable or not, there’s only one sure way to find out if a bagseed will grow. If you’re simply curious to learn and not as concerned with the overall outcome, you can plant a couple of bagseeds outside and see what happens.
If you’re ready for a more serious approach, make sure you have the space for a proper garden and pop the seeds to see what fruit they bear.
Even if your seed sprouts fast and grows vigorously, it still has roughly a 50/50 chance of being female and producing buds, instead of turning out to be a male.
Remember, once a seed germinates, the real work begins. Sexing, selecting, vegetative growth, flowering, and the eventual harvest all lie ahead.
How to buy cannabis seeds
Cannabis seeds can be found on numerous online seed banks, but note that it is illegal to bring seeds into the US and Customs will seize any cannabis seeds that they find in packages or on a person. In legal and medical states, you may purchase seeds at a dispensary.
