Cannabis seeds are ready to plant and grow once they successfully germinate or once the root has broken through the protective outer shell of the seed. Cannabis seeds are available in regular, feminized, and auto-flowering forms. Home growers of cannabis often choose feminized seeds to ensure that the adult plant will be a flowering female.

More about marijuana seeds
As with all angiosperms, or flowering plants, cannabis produces seeds that contain all of the genetic information needed for growth and reproduction. When a seed is planted, the translation of this genetic material dictates each unique physical characteristic the mature plant will have. If these are desirable traits, like potency, smell, vigor, etc., a breeder can select for these through a long process of genetic stabilization through generations, which eventually leads to the creation of a cultivar, or strain.
Anatomy of a cannabis seed
Cannabis seeds are about the size of a peppercorn, ovular in form, and pointed on each end with a ridge that transverses longitudinally on only one side from tip to tip. It is this ridge that opens up during germination. The opposite side is rounded. The body of the seed is brown, but underdeveloped and unfertilized seeds can have an off-white color and are typically smaller in size.

The body of a marijuana seed is spotted or striped, most commonly with light brown specks, but some varieties of cannabis can have red or yellow markings. Plant embryos are contained within seeds and house all cells that will eventually differentiate into leaves, roots, and stems. Embryos, found within the reproductive organs, are protected by an outer envelope called the pericarp. Crucial components of the plant embryo are the cotyledons, the first leaves to appear from the seed, and the radicle, which develops into the primary root. Once the seed germinates and begins its growth into a mature plant, special structures called root caps protect the growing tips of the plant.
Today’s commercially cultivated cannabis does not contain seeds. The cultivation practices that have made this widespread are rooted in fundamental biological concepts. Cannabis is a dioecious plant, meaning it has separate male and female organisms, just like humans. If a female plant matures in the presence of a male plant, pollen from the male will fertilize the female, and its bracts will contain seeds at the end of the flowering cycle. Seedless cannabis is commonplace even when it originates from mass-produced outdoor cultivation, but not too long ago, this was not the case.
Around the middle of the 20th century, growers discovered that culling male plants as soon as they display their sexed traits would result in a crop containing exclusively unfertilized females, yielding cannabis flowers higher in THC that don’t require the removal of seeds before smoking. This seedless cannabis was from then on dubbed sinsemilla, which translates to “without seed” in Spanish. It is also commonly spelled sensimilla.
How cannabis seeds are produced
Commercial growers who produce cannabis flower desire seedless plants but there are also cultivators interested in selling seed to the growing home-cultivation market. Cannabis seed production begins with the pollen grain of a male plant. From this grain, a pollen tube grows, producing male generative cells that disperse in the form of pollen. The migration of pollen into a female plant ovule triggers pistils to fall off and seed production to begin. The bracts, which contain the ovule, will then fill with seeds. Since seeded plants are a natural outcome of pollen fertilizing eggs, producing cannabis seeds is a matter of letting nature take its course.
What’s the difference between feminized, regular, and autoflower seeds?
There are a few differences to note between these cannabis seed types.
- Feminized seeds: The key difference between feminized cannabis seeds and regular cannabis seeds is that feminized seeds have been engineered to produce exclusively female plants. This matters for cultivation since smokable flowers are produced only by female plants. A male plant can potentially ruin a harvest if it pollinates nearby female plants, causing them to produce flowers full of seeds.
- Autoflowering seeds: Autoflowering seeds have been carefully bred to begin and complete the flowering process based on the plant’s maturity rather than how much light the plant receives each day. Autoflowering seeds tend to be simpler to grow and don’t require as much light, making them perfect for places where the growing season is short or for indoor grows.
Is it illegal to buy marijuana seeds?
Marijuana seeds are a cannabis product, so if you live in a place where cannabis is illegal, then seeds are also illegal. However, some people who live in places where weed is not yet legal purchase marijuana seeds from marijuana seed banks as a “souvenir.” Either way, if you want to buy marijuana seeds and cannabis is illegal where you live, then you face some degree of risk. On the other hand, if you live in a state where cannabis is legal, especially one where home cultivation is allowed, then you should be able to purchase seeds legally. Remember, even in states where cannabis is legal, it’s still illegal nationally in the US. To cut your risk as much as possible, purchase cannabis seeds from in-state or local providers so they don’t have to cross state lines or be transported by mail.
Where to buy marijuana seeds
Seeds are sold in brick-and-mortar locations legally in many countries across Europe and are often traded online. As cannabis legalization expands in North America, more retail locations are carrying seeds as well. Feminized seeds are the most popular, but providers likely have access to many strains of mixed male and female seeds. Carefully sifting through cannabis flower before using the grinder will usually turn up a few seeds, too. Professionally sourced seeds assure quality genetics and viability, but saved seeds can be a cheap source of cannabis genetics for the hobbyist grower.
Do dispensaries sell seeds?
If you live in a state or country where cannabis is legal, and where individuals are allowed to grow their own plants at home, then you should be able to buy seeds at most legal dispensaries. This might not be the case if you’re in a location that does not allow home growing. The best thing to do is simply check your local laws and ask your local budtender.
How much do marijuana seeds cost?
A pack of marijuana seeds—typically containing around ten or so seeds—will run you anywhere from around $40 on the low end and as much as $400 or $500 on the upper end. The price of marijuana seeds depends on a number of variables including:
- Quality of genetics
- The reputation of the breeder who produced the seeds
- How rare or potent the strain is
- Whether they’re regular, feminized, or autoflowering (feminized and autoflowering marijuana seeds tend to cost more)
How many seeds should I buy?
If you’re trying to grow just a handful of plants for your own private consumption, then you can get away with purchasing one or two packs at a time. Since most commercially sold marijuana seeds come in packages of 10 or so seeds, 10 to 20 seeds should be enough to ensure a good harvest even if a few seeds fail. This is a baseline for a small, private crop andany larger operations should scale up accordingly.
How to store cannabis seeds
Seed providers sometimes vacuum-seal and freeze seeds for long-term storage, but commercially-available seeds in Dutch headshops are sold in small, plastic vials at room temperature and low humidity (6-12%).
Humidity and light is the main enemy of seed storage. Beyond that, seeds can remain viable for up to two years when stored in even the most haphazard conditions. Marijuana seeds swept up off the floor or found in the bottom of a drawer have been known to grow into vigorous young plants.
Germinating cannabis seeds
Germination is the process of beginning the vegetative growth of the new cannabis plant. Sometimes referred to colloquially as “popping,” this process starts when the seed is exposed to water and light. The seed abandons its state of dormancy, or quiescence, and resumes essential metabolic processes that feed on energy stores to delicately rupture open the shell and grow its first root. This root will elongate until it has taken hold of the medium, after which it will pull two small embryonic leaves (cotyledons) from the seed shell. Cotyledons are in the seed before germination and are not considered “true” leaves. The cotyledons will grow until they are about one centimeter long, and once the stem below this is around five centimeters tall, another set up true leaves will grow out of the top and the stem between the true leaves and cotyledons will continue to elongate.

Generally speaking, cannabis is a hardy plant that will grow and even thrive in a diversity of environments. However, to assure germination, several steps can be taken. One method calls for a moist paper towel inserted into a plastic bag. Once the first root appears, the seedling must be carefully transferred to some soil before the root takes hold to the paper towel.
Cannabis seeds can also be germinated in a peat pellet. Plant the seed only just below the surface. Once the seedling has taken hold in the pellet, directly transfer it to a pot; the roots will grow right through the soft fabric that encases the peat, at which point the pellet can be directly placed into soil. Whichever method is used, keep the temperature between 70 -90 degrees Fahrenheit (21-32 degrees Celsius), ideally at 78 degrees Fahrenheit (about 26 degrees Celsius), keeping seedlings covered to maintain humidity. Seedlings and young cuttings require photosynthetically active radiation that is more heavily weighted in the blue portion spectrum; a common fluorescent desk lamp will suffice until they are about 5 inches, or about 13 centimeters, tall.
Where Are Marijuana Seeds On The Plant?
Where are Marijuana seeds on the plant. In the flower of course
If you are wondering where are Marijuana seeds on the plant, you are not alone. After a female plant gets pollinated by a male plant, you will be able to find marijuana seeds in the flowers after a few weeks. Ideally, you should let the flowers mature completely so that you are able to find marijuana seeds that were on the plant but fell off the flower. These Marijuana seeds are completely mature and can be used, although you won’t be able to know if they are male or female until the plants have been grown out.
Normally when a marijuana plant gets seeds, the potency of the flower will be reduced by up to 30%.

Marijuana’s History: How One Plant Spread Through the World
From the sites where prehistoric hunters and gatherers lived, to ancient China and Viking ships, cannabis has been used across the world for ages, and a new report presents the drug’s colorful history.
In the report, author Barney Warf describes how cannabis use originated thousands of years ago in Asia, and has since found its way to many regions of the world, eventually spreading to the Americas and the United States.
“For the most part, it was widely used for medicine and spiritual purposes,” during pre-modern times, said Warf, a professor of geography at the University of Kansas in Lawrence. For example, the Vikings and medieval Germans used cannabis for relieving pain during childbirth and for toothaches, he said.
“The idea that this is an evil drug is a very recent construction,” and the fact that it is illegal is a “historical anomaly,” Warf said. Marijuana has been legal in many regions of the world for most of its history.
Where did pot come from?
It is important to distinguish between the two familiar subspecies of the cannabis plant, Warf said. Cannabis sativa, known as marijuana, has psychoactive properties. The other plant is Cannabis sativa L. (The L was included in the name in honor of the botanist Carl Linnaeus.) This subspecies is known as hemp; it is a nonpsychoactive form of cannabis, and is used in manufacturing products such as oil, cloth and fuel. [11 Odd Facts About Marijuana]
A second psychoactive species of the plant, Cannabis indica, was identified by the French naturalist Jean-Baptiste Lamarck, and a third, uncommon one, Cannabis ruderalis, was named in 1924 by Russian botanist D.E. Janischevisky.
Cannabis plants are believed to have evolved on the steppes of Central Asia, specifically in the regions that are now Mongolia and southern Siberia, according to Warf. The history of cannabis use goes back as far as 12,000 years, which places the plant among humanity’s oldest cultivated crops, according to information in the book “Marihuana: The First Twelve Thousand Years” (Springer, 1980).
“It likely flourished in the nutrient-rich dump sites of prehistoric hunters and gatherers,” Warf wrote in his study.
Burned cannabis seeds have also been found in kurgan burial mounds in Siberia dating back to 3,000 B.C., and some of the tombs of noble people buried in Xinjiang region of China and Siberia around 2500 B.C. have included large quantities of mummified psychoactive marijuana.
Both hemp and psychoactive marijuana were used widely in ancient China, Warf wrote. The first record of the drug’s medicinal use dates to 4000 B.C. The herb was used, for instance, as an anesthetic during surgery, and stories say it was even used by the Chinese Emperor Shen Nung in 2737 B.C. (However, whether Shen Nung was a real or a mythical figure has been debated, as the first emperor of a unified China was born much later than the supposed Shen Nung.)
From China, coastal farmers brought pot to Korea about 2000 B.C. or earlier, according to the book “The Archeology of Korea” (Cambridge University Press, 1993). Cannabis came to the South Asian subcontinent between 2000 B.C. and 1000 B.C., when the region was invaded by the Aryans — a group that spoke an archaic Indo-European language. The drug became widely used in India, where it was celebrated as one of “five kingdoms of herbs . which release us from anxiety” in one of the ancient Sanskrit Vedic poems whose name translate into “Science of Charms.”
From Asia to Europe
Cannabis came to the Middle East between 2000 B.C. and 1400 B.C., and it was probably used there by the Scythians, a nomadic Indo-European group. The Scythians also likely carried the drug into southeast Russia and Ukraine, as they occupied both territories for years, according to Warf’s report. Germanic tribes brought the drug into Germany, and marijuana went from there to Britain during the 5th century with the Anglo-Saxon invasions. [See map of marijuana’s spread throughout the world.]

“Cannabis seeds have also been found in the remains of Viking ships dating to the mid-ninth century,” Warf wrote in the study.
Over the next centuries, cannabis migrated to various regions of the world, traveling through Africa, reaching South America in the 19th century and being carried north afterwards, eventually reaching North America.
How did marijuana get to the United States?
After this really long “trip” throughout the pre-modern and modern worlds, cannabis finally came to the United States at the beginning of the 20th century. It arrived in the southwest United States from Mexico, with immigrants fleeing that country during the Mexican Revolution of 1910-1911.
“Many early prejudices against marijuana were thinly veiled racist fears of its smokers, often promulgated by reactionary newspapers,” Warf wrote in his report. “Mexicans were frequently blamed for smoking marijuana, property crimes, seducing children and engaging in murderous sprees.”
Americans laws never recognized the difference between Cannabis sativa L. and Cannabis sativa. The plant was first outlawed in Utah in 1915, and by 1931 it was illegal in 29 states, according to the report.
In 1930, Harry Aslinger became the first commissioner of the Federal Bureau of Narcotics (FBN) and undertook multiple efforts to make marijuana illegal in all states. In 1937, the Marijuana Tax Act put cannabis under the regulation of the Drug Enforcement Agency, criminalizing possession of the plant throughout the country.
“Today, the federal government still classifies marijuana as a Schedule I controlled substance, along with heroin and LSD, indicating it has high potential for abuse and addiction, no accepted medical uses and no safe level of use,” Warf wrote.
