Everything You Want To Know About Cannabis Seeds

Let’s Start At The Beginning…..What Exactly Is A Seed?

Dictionary…Seed…Noun: A flowering plant’s unit of reproduction, capable of developing into another such plant.

Wikipedia: A seed is an embryonic plant enclosed in a protective outer covering. The formation of the seed is part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiosperm plants.
Seeds are the product of the ripened ovule, after fertilization by pollen and some growth within the mother plant.

The embryo is developed from the zygote and the seed coat from the integuments of the ovule.
Seeds have been an important development in the reproduction and success of gymnosperm and angiosperm plants, relative to more primitive plants such as ferns, mosses and liverworts, which do not have seeds and use water-dependent means to propagate themselves.

Seed plants now dominate biological niches on land, from forests to grasslands both in hot and cold climates.

What is a Cannabis Seed? Cannabis seeds are one way marijuana plants can propagate. There are other ways of propagation, such as cuttings, layering, division, and budding/grafting to name a few.

Seeds would seem to be nature’s favorite way of continuing a plant species, and they are my favorite way. Clones are great, but I’m kinda old school…I enjoy growing from seed, as well as producing cannabis seeds.

Cannabis is an annual plant, meaning it lives and dies normally in a single season. Photo-sensitive cannabis can, however, be ‘revegged’ or made to grow vegetatively again, even after the plant has initiated flowering, or even when they are done with their life cycle, ie (after the buds are harvested.)

Cannabis is also a dioecious plant, which means that female and male reproductive organs are found on separate plants. Female cannabis plants can be grown without males to produce…. ‘sinsemilla’ or seedless marijuana that is touted to be more potent than seeded marijuana. (and, seeds popping in your smoke is never a good thing)

How To Tell The Sex Of A Cannabis Plant…Male Or Female?

Just a few words about sexing cannabis plants. There is alot of tado about being able to determine which sex your cannabis plants are, but it is really not difficult. Most I think are too impatient, you need to give the plant time to show you. Don’t worry, you will also have plenty of time to respond once the sex of the plant is assured.

So in the images above you can plainly see the white “hairs’ on the female plant. These hairs may be a different color, but will always look similar. As the female plant continues to flower it will produce many more, and they will begin to stack up.

The flowers of the male plants, on the other hand, look completely different. There is only one good male flower in the image above, it is high on the left of the stem. It is, however, all male, that is what the male ‘balls’ look like. The flowers are basically egg-shaped, round looking before they open to release their pollen.

Types Of Cannabis Seeds Available Online

Cannabis seeds come in a few variations:

Cannabis Indica

Indica Type Cannabis Plant
Cannabis Indica

Wikipedia: Cannabis indica is an annual plant in the Cannabaceae family.[1] It is a putative species of the genus Cannabis.

Whether it and Cannabis sativa are truly separate species is a matter of debate. The Cannabis indica plant is cultivated for many purposes; for example, the plant fibers can be converted into cloth.

Cannabis Indica produces large amounts of tetrahydrocannabinol (THC).[2]

The higher concentrations of THC provide euphoric and intoxicating effects making it popular for use both as a recreational and medicinal drug.

Indica Cannabis Seeds come from the cannabis Indica plant. The Indica strains of cannabis originated in the hash producing countries like Morocco, Afghanistan, Tibet, and it’s namesake India.

Cannabis Indica is usually dark green in color and has broad leaves. These plants tend to be short, dense plants. The maturity of this plant is 6 to 8 weeks right after flowering. They usually have dense and thick buds. The flavor and aroma will vary from being pungent skunk to sweet and fruity.

Indicas tend to have higher levels of CBD and lower levels of THC. Which explains the term…couchlock! Pure Cannabis Indica strains will induce a heavy, stony, Cannabis Sativa sleepy stone when ingested. Cannabis Indicas tend to have higher yields than Cannabis Sativa.

Cannabis Indica also matures faster than Cannabis Sativa. Pure Indica plants finish flowering in about 8-14 weeks, while pure Sativas can take 16 weeks or even longer.

Cannabis Sativa

Cannabis Sativa
Cannabis Sativa

Wikipedia: Cannabis sativa is an annual herbaceous flowering plant indigenous to eastern Asia but now of cosmopolitan distribution due to widespread cultivation.[1]

It has been cultivated throughout recorded history, used as a source of industrial fiber, seed oil, food, recreation, religious and spiritual moods and medicine.

Each part of the plant is harvested differently, depending on the purpose of its use.

The species was first classified by Carl Linnaeus in 1753.[2] The word “sativa” means things that are cultivated.

Cannabis Sativa Seeds come from the Cannabis Sativa plant. Sativa Cannabis is a species of the Cannabaceae family (hemp) and can grow tall (up to 20 ft.)

The different cannabis species are also identifiable by their physical appearance. Sativa plants are recognizable by their long, spindly leaves, while Indica plants tend to have long fat leaves. The buds too are long and wispy and have red or orange coloring (hairs). Cannabis Sativa strains originated in the equatorial countries of Colombia, Mexico, Thailand, and South East Asia. Cannabis Sativa thrives in warmer climates.

Naturally occurring Cannabis Sativa plants take advantage of the equatorial sun and can get big, and once a Sativa plant flowers, they can take between 10 and 16 weeks to fully mature.

As cannabis gains more acceptance in mainstream society, the names of the species…ie Cannabis Indica and Cannabis Sativa are now becoming part of the vernacular. As a matter of fact, babies are now being named Sativa.

Cannabis Ruderalis

Cannabis Ruderalis
Cannabis Ruderalis

Wikipedia: Cannabis ruderalis, or C. sativa subsp. sativa var. spontanea, is a low-THC variety or species of Cannabis which is native to Central and Eastern Europe and Russia.

Many scholars accept Cannabis ruderalis as its own species due to its unique traits and phenotypes which distinguish it from Cannabis indica and Cannabis sativa; however, it is widely debated by many other scholars as to whether or not ruderalis is a subspecies of Cannabis sativa.

Cannabis Ruderalis, or C. sativa subsp. sativa var. spontanea, is a low-THC variety or species of Cannabis which is native to Central and Eastern Europe and Russia.

Many scholars accept Cannabis ruderalis as its own species due to its unique traits and phenotypes which distinguish it from Cannabis indica and Cannabis sativa; however, it is widely debated by many other scholars as to whether or not ruderalis is a subspecies of Cannabis sativa.

Cannabis ruderalis is a short and stalky plant. Ruderalis plants typically attain a height of less than 3 feet tall at harvest, they tend to be light green with wider leaves than sativas, and a rough shaggy look to them. Ruderalis buds are small, but still chunky, and are supported well.

What really sets Cannabis Ruderalis apart is that flowering is initiated by age, rather the length of the dark period, as it’s photosensitive cousins Cannabis Indica, and Cannabis Sativa.

Using this trait to its full advantage Cannabis Ruderalis can be crossed with either Cannabis Sativa or Cannabis Indica to create a plant that will contain more THC but begin to flower because of age rather than light cycle. And, there you have the modern-day Auto-Flowering plants.



Wikipedia: Hemp, or industrial hemp, is a strain of the Cannabis sativa plant species that is grown specifically for the industrial uses of its derived products.[1] It is one of the fastest growing plants[2] and was one of the first plants to be spun into usable fiber 10,000 years ago.[3]

It can be refined into a variety of commercial items, including paper, textiles, clothing, biodegradable plastics, paint, insulation, biofuel, food, and animal feed.[4][5]
Although cannabis as a drug and industrial hemp both derive from the species Cannabis sativa and contain the psychoactive component tetrahydrocannabinol (THC), they are distinct strains with unique phytochemical compositions and uses.[6]

Hemp has lower concentrations of THC and higher concentrations of cannabidiol (CBD), which decreases or eliminates its psychoactive effects.[6] The legality of industrial hemp varies widely between countries. Some governments regulate the concentration of THC and permit only hemp that is bred with an especially low THC content.[7][8]

Hemp is a popular subject nowadays, and with good reason. I believe hemp could solve many of the world’s problems because of it’s many and varied uses. Hemp can be used for food, fuel, clothing, construction materials, and even plastic, there are said to be over 50,000 uses for Industrial Hemp!

Most people are unaware that Hemp is actually a strain of Cannabis Sativa. Hemp generally contains little if any THC, but can be a good source of CBD, hence it’s much toted medicinal effects. Industrial Hemp is quickly gaining acceptance, and will likely be grown extensively in the near future.

How Cannabis Seeds Are Made

Many plants rely on bees, birds, and other animals to aid with their pollination. Cannabis, however, is one of about 80% of plants that rely simply on the wind for pollination. Cannabis pollen can travel miles to do the deed.

A female cannabis plant must be pollinated by pollen from a male plant in order to make regular cannabis seed(cannabis seed that will produce both males and females at about 50/50.)

Cannabis breeders have developed several types of cannabis seeds that are commonly bought online:

Cannabis seeds that are available for purchase online come in one of these cannabis strain configurations…

Cannabis growers must be aware of the cannabis plants ability to hermaphrodite or, for female cannabis plants to produce pollen that is laking the Y, or ‘male’ chromosome. This ‘pollen’ created by the female plant will produce only female offspring. This is how feminized cannabis seed is produced. More on that a bit later.

Landrace Cannabis Seeds

Landrace Cannabis Seeds are simply a pure strain of cannabis, either Indica, Sativa, or Hemp. These strains should be genetically pure, and should not be hybridized. There are many landrace cannabis strains available for purchase online. Pibeurt, and Santa Marta Colombian Gold, and the Tajikiatani Hash Plant are a few I carry right now.

Indica Cannabis Seeds

Indica Cannabis Seeds if unhybridized and from pure Indica genetics are considered a landrace strain. These seeds are commonly available for sale online.

Sativa Cannabis Seeds

Sativa Cannabis Seeds can be pure and unhybridized as well. They too would be considered a landrace strain, and readily available to purchase online.

Hybrid Cannabis Seeds

Hybrid Cannabis Seeds are seeds that have been crossed. Hybrids can be produced by crossing any of the cannabis strain with another….some common crosses…Sativa/Indica (very common hybrid), Ruderalis/Indica (produces an auto-flower), Ruderalis/Sativa (again produces and auto-flower.)

Auto-Flower Cannabis Seeds

Auto-flowering Cannabis Seeds are simply a cross between the Ruderalis cannabis strain and either an Indica, or a Sativa. The Indica or Sativa give the cross potency, and the Ruderalis takes away the photosensitivity common with most strains.

Autoflower cannabis hasn’t been around for too many years, but are starting to gain traction. The advantages of no photosensitivity, the speed with which they mature, and the time they are in the ground make auto-flowers a great choice for beginners.

Feminized Cannabis Seeds

Feminized Cannabis Seeds are produced by ‘forcing’ a female cannabis plant to hermaphrodite, or produce ‘female’ pollen in a last-ditch effort to continue the plant species. Female cannabis plants can be ‘forced’ to hermaphrodite by several methods…

  • Rodelization
  • Colloidal Silver
  • Gibberellic Acid

Rodelization is taking advantage of the plants’ last-ditch effort to continue the species in the absence of a pollen-producing male marijuana plant. As female cannabis plants continue to flower and age, some can produce ‘female’ pollen if you will, this pollen lacks the y chromosome and produces seed that grows only female plants. This is one way to produce feminized cannabis seeds and the way most people do it ‘accidentally.’

Colloidal Silver is mixed with distilled water to the recommended strength, then sprayed on the blooming female cannabis plants….basically ‘forcing them to hermaphrodite and produce pollen, again lacking the Y chromosome, thus producing only female marijuana seeds and plants.

Gibberellic acid is used in the same way as colloidal silver. Gibberellic Acid comes in a powder that you mix with distilled water and spray on the blooming female cannabis plant. This like colloidal silver causes the female plant to produce pollen, which again will only grow into female plants.

Another way feminized cannabis seed is produced is by spraying the blooming cannabis plant with colloidal silver water. This effectively ‘forces’ the female cannabis plant to become a hermaphrodite and produce pollen. This pollen will again produce only female offspring.

There is a third way to propagate only female cannabis plants…cloning. Cloning is the act of rooting a cutting from a plant. The clone will be a duplicate plant…just like the plant the cutting was taken from. A clone will be the same sex as the parent plant and will be basically identical.

Good Cannabis Seed Or Bad Cannabis Seed….How To Tell

Cannabis Seeds are not all created equal. Some may not have matured long enough and will be immature, and difficult, or impossible to get to sprout.

Cannabis Seeds
Good Cannabis Seeds and Bad Cannabis Seeds

Cannabis seeds should not have cracks, nor any damage to the outer shell. No dents either, they should be round, smooth, and cylindrical.

Good cannabis seeds should be good-sized, and fairly dark. Good seeds should have a hard shell, that will stand up to a good squeeze. Bad cannabis seeds tend to be a lighter green, and smaller. Here is an image of two rows of great seeds on the left, lower quality, but still likely viable seeds in the third row, and immature, unsatisfactory seeds in row four.

Another factor involved in seed quality is the age of the seed. Cannabis seeds lose viability with age, so if you buy cannabis seeds and they are difficult to germinate…the age of the seed could be the culprit. We do periotic germination tests here at Just Cannabis Seed to assure a high germination rate.

How Genetics Affects Seed Quality

High Quality Genetics

Although great genetics does not mean your seeds will be more mature, nor that they will germinate better, but genetics has everything to do with your finished product.

If you want to grow high-quality bud, you need to start with seeds produced from high-quality genetics.

Look at it this way, you are going to all the time, and trouble, and expense, to grow great cannabis plants. So why grow substandard bud?

Do yourself a favor and start with killer genetics. All seed sold here on JustCannabisSeed.com comes from some of the best genetic make-up around.

This bud on the left is a very popular strain developed at New 420 Seed Guys called Paul’s Purple Fire, and available here on site.

How To Store Cannabis Seeds

So you have ordered and received your cannabis seeds, and you don’t want to grow them all out right away. What to do? How should cannabis seeds be store to retain their viability? Here are four things you can do:

  • Keep them dry
  • Keep them sealed airtight
  • Keep them cool
  • Keep them in darkness

Keep Your Cannabis Seeds Dry

Make sure your cannabis seeds are stored dry. A moisture percentage in the 2-3% range is ideal for storing your cannabis seeds. A desiccant can be placed in the storage container with your seeds. Pre-packaged desiccants or silica gel packs are readily available online. Rice can also be used is as an effective desiccant, but should be replaced periodically. The use of a desiccant when storing seeds greatly improves their stability, longevity, and viability.

Keep Your Cannabis Seeds Sealed Airtight

This is a very important step when storing your seeds. If the seed bank you ordered your cannabis seeds from sends them in a sealed container, perhaps containing a desiccant, you can simply leave them unopened for long term storage.

Cannabis Seeds Stored in a Glass Jar

When storing your own seed long term consider purchasing a vacuum sealer. IMO this is the best way if you do not need to access the seeds for some time. Plastic containers are not recommended, nor are baggies. For long term storage glass containers with sealable lids are best. If you need to get to them from time to time a glass canning jar with a sealable lid is a good choice.

Overall, glass containers are highly recommended for optimum storage conditions. They are suitable for long- and short-term storage. A glass jar with a glass lid is ideal, but glass canning jars with metal lids work fine too. Reusable, airtight, and easily assailable long and short term storage of your precious cannabis seeds.

Keep Your Cannabis Seeds Cool

When storing your cannabis seed temperature is another important factor to consider. If you are storing your seeds for just a few years room temperature can work well, making sure they are airtight and in darkness.

Some people keep their seeds in a refrigerator. This can work well, but you must keep in mind refrigerators are somewhat humid, if your seeds are stored there they must be in airtight containers.

Many also keep their seeds long term in a freezer, this method I do not recommend. Freezing your seeds long term can actually destroy tissue and damage the seeds. If you decide to go this route the seeds must be airtight, and care must be taken to not thaw and refreeze, as this is especially hard on seeds stored frozen.

Keep Stored Cannabis Seeds In Darkness

Light has a way of deteriorating things, and cannabis seeds are no exception. Always store your cannabis seeds (no matter where) in complete darkness. I like storing mine in a drawer in my dresser, closed and dark. If you decide on a refrigerator or a freezer that should still be kept in complete darkness.

In Conclusion

Cannabis seeds are natural living entities, and although they are hardy and lasting, care must be taken in order to keep them longer then nature intended. Store them properly and you can enjoy the fruits of your cannabis husbandry for many years to come!

Is Buying Cannabis Seeds Online Legal?

Sorry Disclaimer Time…

All content presented within this website is for informational purposes only and does not in any way provide legal advice. Before you buy cannabis seeds online you need to know the laws in the place you reside. You also need to follow the laws in the region you reside in. I in no way encourage you to break any laws that are in place.

You, like people all over the world, want to grow this wonderful plant. Seeds are the easiest way to accomplish this. (clones are great, but not as readily available as seeds in most locals) There are likely hundreds of seed banks online who would love to sell you the cannabis seeds you seek. One main difference between my site and theirs is price. Just Cannabis Seed is a discount seed bank, I will sell always my cannabis seed at cheap, discounted prices.

The laws governing the sale, possession, and germination of marijuana seeds vary widely. Cannabis is illegal federally here in the USA. (soon to change at the time of this writing) This makes buying, growing, and simply possessing seeds complicated at times. Cannabis seeds contain no THC, which adds to the confusion. The seeds are basically legal to own in the USA, and much of Europe. We add a strong disclaimer here on the website, and in our packaging. In many locals, they are simply illegal to germinate.

We will ship cannabis seeds to the USA, most of Europe, and Australia. Most business comes from within the USA.

In conclusion, the laws governing obtaining, possession, and germination of cannabis seeds vary widely and are seemingly always in a state of flux, but if you want to get the best deals on high-quality cannabis seeds, well you have come to the right place.

I am committed to providing the best seeds from the best genetics for medical and/or recreational users at the cheapest price you will find anywhere online. I can also provide bulk, wholesale deals on many of the strains I carry.

Why Do Cannabis Seeds Cost So Much Online?

Medical Cannabis
Cannabis Medicine

The risk, illegality, and the time it takes to breed a new strain of cannabis all add to the high cost of seeds online. Many cannabis seed banks are simply ‘resellers.’ They don’t create new stains at all, but simply buy seeds wholesale and resell those seeds online.

And, many so-called breeders simply cross two strains and sell their F1 hybrids. I do think many seeds sold online are priced too high. Especially if they are a F1 hybrid. But, the price line is based on what the market will bear. If you are willing to pay those prices you will see those prices….hint…buy mine cannabis seeds they are way cheaper!

Here at Just Cannabis Seed, I keep my prices low, especially for seeds that I have an abundance of. I will always have seeds on sale for around a couple bucks a seed. I do bulk deals for even cheaper, depending on how many seeds you buy. So if you are tired of those high prices, but still want killer genetics for highly discounted prices….shop now.
