- What are Cannabis Seeds? Marijuana Seed Definition
Starting cannabis from seed can be extremely rewarding. Not only do you get to take your plants through a complete growth cycle, but you might also get to produce some seeds of your own. With seeds, anyone can go from a cannabis enthusiast to an amateur breeder.
You’ll be able to custom tailor your plants to meet your specific needs or possibly develop a new strain or two. To help you experience the wonders of seeds, we’ve created this article – the ultimate guide to growing cannabis seeds.
What Are Cannabis Seeds
Cannabis seeds are obviously the seeds of our favorite herb, but can you grow any old seed into a flowering weed plant? The important thing for successfully growing cannabis is to only cultivate female plants. Female plants will provide you with the highest quality flowers for smoking. However, those same female plants should be seedless, so where do cannabis seeds come from?
Cannabis seeds are produced when a male plant fertilizes a female plant. You don’t want this to happen if you’re growing females for smokable flower because then the buds are cluttered with seeds. That’s why cultivators isolate their female plants as soon as they identify the sex, and you should too.
Of course, if seeds are desirable for reproduction or hemp seed oil, then this process is allowed to happen. However, when it comes to creating cannabis seeds to produce a new generation of plants, there are some other techniques experienced cultivators will use.
How To Find And Choose The Right Cannabis Seeds
If you’re growing from a clone, it’s unlikely that your plant will produce seeds. Seeds develop after a male cannabis plant pollinates a female. Only female plants produce seeds. Yet, when you smoke cannabis, you’re typically smoking the unfertilized bud of the female flower. This can make it a bit difficult to actually find seeds if you’re interested in growing from scratch.
There are a couple of ways you can source your seeds. If you live in a legal medical or recreational state, ask your favorite dispensary for reputable local seed companies. Many people also order seeds from online seedbanks such as ILGM. Though, this is illegal in the United States. Seeds for “souvenir purposes” are legal in many regions around the world, allowing many seedbanks to ship worldwide.
Though ordering seeds is illegal in the U.S. and you can face criminal charges, seed arrests are uncommon in comparison to arrests from growing or germinating plants. It’s not uncommon, however, to have your mail-ordered seeds confiscated by U.S. customs. If you order seeds from an international seed bank and they are found, you will get a letter in the mail saying that your seeds have been tossed out.
Do All Cannabis Plants Produce Seeds?
Cannabis plants only produce seeds after a male plant pollinates a female plant. It’s uncommon to find seeds in dispensary quality bud, and it’s also unlikely that your plants will develop seeds if you’re growing from a clone. When you smoke or vape marijuana, you’re typically consuming the unpollinated, seedless female flower. This part of the plant is named sinsemilla, meaning “without seed”.
Female plants produce significantly more resin than male plants, which is why bud from female flowers is what we’ve come to cultivate for harvest. Marijuana resin in the form of trichomes produces has a crucial role in the plant’s reproductive cycle.
The trichome-heavy female marijuana bud is designed to capture male pollen spores in order to develop seeds and reproduce. When females are kept away from the males, not do you create sensimillia, but you also kickstart trichome production.
So, while all female plants are capable of producing seeds, pollination is required for their development. Breeders and seed banks play the part of geneticists and help spur evolution by selectively mixing pollen from specific male plants with the genes from selected female plants. This creates seeds featuring hand-selected and carefully chosen traits.
How To Choose Your Seeds
Look For These Traits
Finding seeds may be a little tricky, but choosing the right seeds to grow is easy. There are a few qualities that set good seeds apart. When you’re picking out your seeds, watch for these features:
- Color: Look for a dark brown teardrop-shaped seed. Some seeds have dark stripes or splotches of different brown, black, or tan shades. Avoid pale or green seeds.
- Size: Indicas produce larger seeds with striping. Sativa seeds are smaller and more uniform in color.
- Hardness: A good seed has a hard outer shell. Don’t pick seeds that are soft or damaged.
Select The Right Strain
Thanks to all of the innovative breeders out there, modern day marijuana has become a very diverse plant. You can find fast-growing varieties, varieties designed for perfect outdoor yields, and strains selectively bred to grow well indoors. Short, stocky indica plants are typically the best indoor choice. If you’d like a plant that grows to a manageable size but has more of a sativa high, you can find a balanced hybrid with ease.
Doing a little research ahead of time will help you avoid splurging on seeds that are difficult to grow in your intended environment. If you’re lucky enough to have a great outdoor grow space, a slower-growing sativa will make the best of the outdoor season.

You can order cannabis seeds online from seed banks, but it can get confusing with all the different types of seeds available. The first thing you want to do is decide which strain you want to grow. Most seed bank sites will have a selection, sometimes organized by indica, sativa, hybrid, high-CBD, or by their medical or recreational uses.
The first category of cannabis seeds you’ll likely come across is “feminized seeds.” As you probably guessed, this is referring to the gender of the plant. While female plants are desired for growing smokable flower, there are pros and cons to feminized seeds.
The most obvious pro to growing weed from feminized seeds is getting a female plant. In fact, many breeders advertise having a “100 percent” success rate with their feminized cannabis seeds. This saves growers the time of identifying and separating male and female plants.
However, as experienced breeders are well aware, feminized seeds run the risk of developing into hermaphrodites. Female cannabis plants can form a hermaphrodite condition, where male flowers grow on the same plant, alongside female flowers, for a variety of reasons. But the biggest danger here is the male flowers self-pollinating the female flowers. All the resulting buds will be littered with seeds and not ideal for smoking.
At the same time, feminized seeds are an easy option for newbie growers and medical cannabis patients. Just be sure to keep an eye on those plants.
The next term you’ll come across when shopping for weed seeds is “auto-flowering.” If you’re familiar with some cannabis cultivation basics, you know that the plant has a vegetative growth period and then switches into a “flowering” period where it grows the buds we know and love. What activates that switch is the change in light, from long days to shorter ones as would happen naturally when the seasons change from summer to fall.
In the spring, blue light wavelengths are more predominant. Plants rely on this blue light to prosper during vegetative growth. During the late summer and early autumn, red wavelengths of light from the sun become more abundant. This red light is packed with the energy the plant needs to develop complex flowers.
To flower photoperiod plants early, most indoor growers put the plants on a strict 12/12 light schedule. Meaning 12 hours under the lights followed by 12 hours of complete darkness.
Auto-flowering seeds, however, are different. Auto-flowering cannabis seeds don’t require a change in light to enter the flowering stage in their life cycle. They naturally begin flowering after a certain amount of time instead.
As a result, most auto-flowering plants are ready to harvest in under 10 weeks. Flowering often begins at a mere two to four weeks.

Cultivators developed these seeds by breeding regular high-THC Cannabis sativa with its very close relative Cannabis ruderalis. Cannabis ruderalis is a type of cannabis that grows in the wild. It’s typically smaller than Cannabis sativa and has a much lower THC count. However, when crossed with high-THC strains, breeders have developed auto-flowering plants with high THC counts that are low maintenance.
Though there is variation from strain to strain, auto-flowering strains tend to be much smaller than their standard counterparts. As a result, yields from auto-flowering plants tend to be slightly less. On the high end, some auto-flowering cannabis seeds can yield up to 150 grams per plant, though the average is somewhere in the double digits.
Auto-flowering seeds are particularly useful in northern climates, which have extremely long summer days. Once the nights become long enough to trigger flowering, the rain and frost soon follow.
This means that many plants fail to develop full flowers before the cold arrives.
Auto-flowering cannabis seeds also have some advantage indoors, especially for those who love sativas. Auto-flowering plants are generally small, compact, and can handle a wider range of grow environments.
Sativas, on the contrary, are tall plants with a long flowering period. Starting with auto-flowering, sativa seeds makes it easier to grow these wily plants indoors.
Most indica plants, however, are also short and perform well indoors regardless of whether or not you start with auto-flowering seeds.
Critics of auto-flowering seeds often find fault with the low yields of the plant. A photoperiod sensitive indica will produce short, manageable plants with a much higher yield than many auto-flowering varieties.
However, auto-flowering strains provide growers with the ability to produce extremely fast, easy to grow crops with excellent adaptations to the cold.
How To Germinate And Sprout Your Cannabis Seeds
In many places, cannabis becomes illegal once seeds begin to germinate. Germination is simply the process of getting your sprouting your seed to grow a plant.
If you are able to safely germinate your seeds, there are a few ways to go about the process.
Almost every grower has their preferred germination method, but here is a brief summary of the most popular techniques:
Basically, pre-soaking means that you soak your seed in warm (not too hot!) water until they sink to the bottom of your glass or container. The idea is that soaking your seeds speeds up the germination process by making sure that your seed is completely moist before planting.
Some people soak their seeds for up to seven days, or until a root appears. Though, the major concern here is that pre-soaking increases the risk of rot and mold before you’ve even fully started your plant.
The benefits of pre-soaking your seeds are debated among growers. Some people swear by it, and others suggest that you risk exposing your seed to rot if it gets too far along in the germination process before it’s removed.
Pre-soaking speeds things up a bit by ensuring that the seed is fully moist before being put into the soil. It also helps you test the viability of the seed prior to planting – a seed that will germinate will absorb water and become soft. You may also notice a root beginning to emerge after taking the seed out of the water.
Here’s How To Do It
- Fill a shot glass or small tumbler halfway with purified or bottled water. Avoid using tap water as it’s often treated with chlorine or other substances which can impact growth. Most of the time, tap water is ok, but if you really want to give your seeds the best chance of producing a top-quality product, it’s worth it to be picky.
- Add in your seeds. Avoid overcrowding. You want the seeds to float at the top of the waterline, so don’t put in so many that they’re completely submerged from the get-go.
- Place the seeds in a warm, dark place with a constant temperature. Germinating seeds do not like light, but they do need a certain amount of heat to get going. On top of the water heater is usually a good spot. Consider covering the shot glass with another plastic cup to help keep things clean and dark. The ideal temperature is around 75-80 degrees F or 22 degrees C.
- Wait for the seeds to sink. Many growers suggest letting the seeds soak for up to 24 hours. But, the most important thing is to wait until the seeds sink to the bottom of the glass. When they sink, you know that water has permeated the outer shell and the seeds are thoroughly moist. Don’t let them sit submerged for too long, as that may drown them or increase the likelihood of rot.
- Gingerly remove the seeds from the glass. Because the seeds are soft and possibly already showing root, you want to avoid damaging them. One way to easily get the seeds out of the glass is to carefully pour them out over another glass or a large strainer that has been covered by a paper towel. You can then more easily pick them up from there.
The Paper Towel Method
The paper towel method is one of the most popular germination methods out there. It takes a little longer than the pre-soak method, but there’s less of a risk of rot if you’re observant. You simply moisten a paper towel, fold it, place the seeds inside the fold, and then place the damp towel into a plastic baggie.
Keep the plastic baggie in a dark, warm place, but keep an eye on it so that it doesn’t mold. After a couple of days, a root will appear. You can then transfer the germinating seed into soil.
Here’s How To Do It
- Dampen the paper towel with purified water. You’ll want to make sure that the paper towel isn’t dripping wet, as that increases the opportunity for rot. Misting the paper towels with a spray bottle rather than dunking them into water will ensure that they don’t get too wet. Damp cotton rounds can also be used in place of paper towels.
- Place your seeds in the middle of the damp paper towel and fold. Make sure your seeds are decently spaced from one another, and are completely covered by the paper towel.
- Keeping the paper towel horizontal, slip the moistened cloth into a plastic baggie. Seal the bag part way, and make sure it stays horizontal.
- Blow a bit of air into the plastic bag. Once the bag is slightly puffed up, seal the air inside. Seeds need a little air to germinate. Store the baggie in a warm, dark place.
- Check your seeds daily to see if they’ve begun to sprout. Once a taproot begins to show, they’re ready for soil. As with the pre-soak method, make sure you handle your seeds with care to avoid damaging them.
Direct Soil Method
You can plop your seed directly into soil whether or not you’ve pre-moisten it in any way. Have a small container of prepared soil ready. Make a tiny, half-inch well in the soil. If you’ve pre-soaked your seeds, place the seed root-end down. If you’re starting with dry seed, place it pointed end down. Flick a tiny amount of soil back over the seed. Then moisten the soil with a sprayer or small amount of water.
If you started from a dry seed, cover the container with plastic wrap to create a greenhouse effect. Store your newly planted seed in a warm, dark place. After about 4 to 5 days, your seeds will sprout. At this point, move your seeds to a brighter, well-ventilated location and wait for them to get large enough to transplant.
Here’s How To Do It
- Fill a small container filled with prepared soil, a peat pellet, or rockwool. If using soil, use your finger or a pencil eraser to create a divet about 5mm deep. Aim for a well about twice as high as the seed you’ll be putting in.
- Place your seed inside the well. If you’ve pre-soaked the seed, place the root-end down. If you’re germinating in the soil itself, place the seed pointed end down. Gently flick a little bit of soil over the seed, but don’t compact it down. You just want a light dusting that will help keep the seed moist and dark. You don’t want to make it too difficult for a sprout to push out.
- Use a spray bottle or mister to moisten the soil. You’ll want to make sure that the soil is damp, not overly wet.
- If your seed hasn’t germinated prior to planting, cover your container with plastic wrap. The plastic wrap creates a greenhouse effect and retains soil moisture by capturing evaporated water and condensing it back into sweat. If you’re using peat pellets or small soil cups, you can also purchase a greenhouse box with a plastic lid at a local garden store. The ideal humidity is between 70 to 90%.
- Wait for your plant to grow! After about 4 or 5 days, you’ll notice that your seeds are beginning to sprout. At this point, you’ll want to make sure your plants are well ventilated and have access to light. Remove any plastic wrap or take off the greenhouse lid. Place the seeds in front of a south-facing window where they’ll have access to the sun. Or, place them under a plant light. 18 hours under light and 6 hours in complete darkness typically yield the best results. At this early seedling stage, plants are still fragile. Make sure their environment is still warm. The soil should be damp, but not too wet.

Once your seedlings have well-established roots, you can then transplant them into a bigger container. They’ll typically reach this point after 2 to 6 weeks as seedlings.
The tell-tale sign that they’re ready to be moved is when you see a sudden spike in leaf growth, indicating that the plants are now in a vegetative growth phase. The leaves will be recognizable as marijuana leaves.
Giving your seeds a fighting chance from the beginning is a must if you want a top-quality harvest. Like in humans, what happens in the initial stages of development is important for the overall survival and health of the plant.
If you happen to have enough seeds, you may want to try each of the methods outlined in this article to see which garners the best results for your particular growing style.
Can You Tell The Sex Of A Cannabis Plant From The Seed?
Some may claim that they can tell whether a plant is male or female simply by looking at the seed. Is this actually possible? No.
Unless you specifically buy feminized seed, there is no way to tell whether or not your plant is a male or a female prior to early bud development. Both male and female seeds look exactly the same.
How To Sex Your Cannabis Sprouts
When your little plants reach about the 6-week mark, you’ll be able to tell their sex. If you’ve started from feminized seed, you won’t need to worry about this step. Feminized seeds only produce female cannabis plants, making them great options for folks who plant to just grow from clone after their initial start with seeds.
If you’re not growing from feminized seed, sexing your plants is one of the most important parts of the early growing process. In order to get a good harvest of usable cannabis flower, you’ll need to separate your male and female plants. If you do not separate your plants, you risk unwanted pollination.
When female plants are pollinated, they stop spending energy on developing potent buds. Rather, they spend energy developing seeds. Here’s a brief summary of what to look out for.
Pistils like this mean that your plant is female
The first and foremost way to tell whether or not your plant is a female is to watch for the development of pistillate hairs. When you pick up some dried bud at a dispensary, you’ve probably noticed the orange hairs that cover the dried flower. The bud of a growing female plant will begin to grow these hairs as soon as a flower begins to form.
These pistillate hairs are white while the plant is young and growing, but they’ll often turn dark orange or red once it matures and the flower is cut and dried.
In a young plant, look for a small bud with one or two long, white protruding hairs. These hairs are unique to females. So, if you see them, you’ll know that the plant will produce a potent, smokable flower as long as it remains unpollinated.
As female flowers mature, they grow to look like the flower we’re most familiar with finding in marijuana dispensaries. Male flowers, however, develop bulbous “pollen sacks” which make them easily identifiable.
Look for a tiny, tulip-like bulb without any pistillate hairs sprouting from the top. Once your plant begins to show signs that it is male, you should separate them from female sprouts. If you leave the two together the male plant will produce pollinate the female plant as it matures.
Once the female plant is pollinated, it will begin to expend energy producing seed rather than further developing its flower. This is great if you’re hoping to create and save your own seeds. But, if your goal is to get a great harvest from your female plants, you’ll want to avoid pollination.
How To Create Your Own Cannabis Seeds
There are a lot of reasons to hang on to male cannabis plants. The best reason?
You can use them to create your own seeds. You can either pollinate an entire female cannabis plant for a TON of seeds, or you can pollinate select branches to save some of your harvests and still have some seeds for next year.
To begin, you’ll need at least one mature male and one mature female cannabis plant. As we mentioned before, male marijuana plants produce the pollen needed to fertilize female plants and create seeds.
Male plants tend to mature about two weeks ahead of female plants. So, you’ll want to keep them alive and thriving while you wait for female plants to mature. You can do this by selectively pruning back your male flowers throughout the growing season until you’re ready to pollinate your females. Prune male flowers that are growing the fastest, while allowing slower growing or late buds to mature.
A female plant will be ready for pollen after she’s begun to produce good flowers. The flowers themselves should have developed numerous long pistillate hairs and be decent in size. Once she’s reached the proper developmental stage for pollination, you have a couple of choices when it comes to how you’d like to go about and produce seeds.
Pollinating Your Females

Option 1: Let Nature Take Its Course
If you’ve been following along, you know that your male plants and female plants should be grown in separate locations to avoid unwanted pollination. One slightly difficult way to pollinate your females is to simply move one of your female plants into the same room as your favorite mature male plant.
Once together, give the male plant a good shake to cause the pollen to spread around the air and fertilize the female. After a day or two and a few good shakes of the male plant, you can then return the female to a proper growing environment so that it has the light and resources it needs to produce seeds. Or, you can continue to grow the two together if there’s enough of the proper light and nutrient resources around.
While this option mimics what typically happens when pollen just-so-happens to reach female plants in the natural world, this method isn’t exactly ideal if you want an easy, controlled way to produce your own seeds. For one, pollinating an entire female plant means that you’ll be doing an awful lot of digging once seed-harvest time roles around.
You also waste some potentially good bud this way. Pollinating an entire plant will produce a whole hell of a lot of seeds. If you’re growing as a hobby or for your own personal use, you really won’t need that many seeds.
Option 2: Pollinating Select Branches
This option is a little nicer for home growers who may not have very many plants to begin with and don’t want to use an entire female for seed creation. In this option, you’ll only be pollinating a few select branches of a specific plant. This will give you significantly fewer seeds than pollinating an entire plant, but it is relatively easy and will give you enough of a yield to replenish your next round of crop.
Here’s what you’ll need:
- 4 to 6-inch flower clippings from a mature male flower
- A female plant with pruned lower branches featuring decent sized flowers
- Long paper wine bags
- String or zip-ties
Once you’ve selected both a male and female plant that you would like to breed, you’ll need to prep each one for pollination. For the female plant, this means pruning back the fan leaves surrounding the branch(s) that you’d like to fertilize.
For the male plant, you’ll need to make some clippings of some good looking flowers and place them into the wine bags. Use at least one sizable clipping per bag. Paper sandwich bags are also OK, but make sure they can fit both male clippings and fully encompass your female branch. Long bags really work the best.
Next, place the bag containing the clippings around the prepped female branch and tightly secure the end of the bag around the branch with either, string, easy-to-peel masking tape, or a zip-tie. Give the bag a good shake. Let it sit for a couple of hours, shaking one or two more times.
Be careful during this entire process. You’ll want to avoid pollinating nearby branches that you’re trying to save for a harvestable crop. It’s advisable to avoid wind, and turn off fans while you’re pollinating certain branches,
After a couple of hours are up, remove the bag very gently. Again, avoiding pollination of other branches. If you’re worried about getting pollen on crop flowers, you can mist off the pollinated bud after about 48 hours.

Finally, after all of that tricky pollination business, you can expect mature seeds in about 4 to 6 weeks. As the female plant develops its seeds, you’ll notice that fertilized bud looks quite different from an unfertilized flower. For one, you won’t get the huge colas and beautiful, thick, dense trichomes that you’d expect to see from your standard, consumable sinsemilla. Rather, seed buds look a little more bulbous and are much, much smaller.
After several weeks of ripening, you can test to see if your seeds are mature by picking one out. A developed seed will be dark brown or a deep tan, have an incredibly hard outer shell, and may feature visible stripes. If you’ve fertilized only select branches, you’ll want to leave the pollinated branches on the plant a bit longer than your crop flowers.
Once you’ve determined that your seeds are mature, don’t be afraid to really dig into the plant to get them out. The remains from seed-producing flower are significantly less potent to consume than unfertilized plant material.
And there you have it! Those are some very basic tips to produce your own marijuana seeds. Now you’ll be able to crossbreed your best growing male plants with particularly high-yield females to ensure that you’re getting a premium crop with every new batch of seeds you plant.
How To Store Cannabis Seeds
After you have found your seeds, germinated your plants, gone through the growth cycle, and cultivated your own seeds, you better know how to store them right. Cannabis seeds can last for years when kept in the right conditions. This means that if you’ve found a strain pairing that you really love, you can come back to it time and time again. For the most part, always remember these three rules:
- Don’t keep your seeds in direct sunlight. Find somewhere dark
- Keep them away from moisture. Store them somewhere dry
- Pay attention to temperature. Pick a cool place
There are a couple of common seed storage methods out there, and each one has its pros and cons. Here is a brief summary of popular techniques:
Some folks have been able to successfully germinate seeds after storing them for 10 years in a refrigerator. Though, this method is debated among growers and breeders out there. If you open and close your fridge a lot, the seed will be subjected to sudden temperature changes. You also risk exposing your seeds to excess moisture, allowing them to rot.
To protect against these concerns, keep your seeds in an opaque airtight container. Throw in a food-grade desiccant pouch to suck up any moisture. Vacuum sealing your seeds with desiccant also works well.
Freezing is another seed-saving technique that sparks debate. When you freeze seeds, some of the cells will rupture because of the bitter cold. You also risk drying the seeds out the longer they’re kept in such intense temperatures. However, some folks swear by the freezer method.
If you want to try some freezer seeds, keep them in a vacuum sealed container with a food-grade desiccant. Make sure they aren’t exposed to too much light or drastic swings in temperature.
With both the freezing and refrigeration methods, make sure you warm your seeds to room temperature before trying to germinate them. Just let them sit out for a bit in a dark container. You don’t want to shock the seeds with sudden temperature changes.
Growing from seed is a beautiful thing. Taking your plant from seed to sprout to full-bloom is a miraculous and therapeutic experience. Growing great cannabis takes a bit of forethought and preparation, however. It’s best to do your research ahead of time and plan out what approach you’re going to take with your plants.
Where To Buy The Best Cannabis Seeds
Choosing the right cannabis seeds will depend on your goals, experience level, and grow space. If you’re growing outdoors, you won’t need auto-flowering seeds. But if you’re growing indoors for the first time, opting for auto-flowering, feminized seeds is definitely an easy place to start.
If you want to try growing some weed seeds you found in your bud, it’s important to check if the seed is mature. If the coloring is a dark brown color with an almost tiger-strip-like pattern, then you’re good to go. But if the seed is a light, off-white color, it’s not ready to be germinated.
Ask Your Local Dispensary
If you’re lucky to live in a state that allows home growing either recreationally or for medical use, then you may have an easier time finding seeds. In California, for example, medical cannabis patients can obtain seeds that were produced inside of the state without violating state law. However, they cannot be sent via mail and you must have your medical marijuana authorization verified in order to acquire them.
Every marijuana state, whether it’s medical only or includes recreational, has its own unique cannabis laws. Asking a local dispensary or connecting with an in-state breeder can give you more information about the laws in your particular region. For the most part, viable seeds that come from out of state sources, be it domestically or internationally, are still illegal.
Online Seed Banks
U.S. Customs laws are quite odd. Having seeds shipped to you domestically, from another U.S. state can get you into trouble. But, ordering seeds from another country seems to be a weird gray area. There are quite a lot of international seed companies out there, and many that ship to the U.S. have been in business for quite some time.
This is quite strange, considering that sale and trade of marijuana products is federally illegal. Many seed companies attempt to get around this by selling seeds as “souvenirs” that are not to be germinated.
According to GrowWeedEasy, if your marijuana seeds are confiscated while in route from another country, they’ll most likely be tossed out by customs officials. You’ll also get a letter saying that your package has been taken because it violates customs laws (see video above). If that happens, many seed banks will typically send you another package free of charge.
Having seeds is illegal under federal law as well as in states that don’t allow home growing. It’s definitely still possible to face legal repercussions from ordering seeds, but many mail-order enthusiasts will tell you that it isn’t that likely. If it’s illegal to grow in your region, you will probably face legal repercussions if you’re caught with germinating seeds. Having viable seeds in your possession is still a risk, however. So, it’s really up to you to make the personal decision of whether or not you want to order.
Beware of fraudulent seed companies that will take your money without sending you anything, or will send you things you didn’t order.
Growing from seed can be extremely rewarding. Not only do you get to watch your plant sprout from what seems like nothing, but you also have more of an opportunity to mix and match and play with genetics. Clones are typically easier to come by in most marijuana states, but if you’re lucky enough to have access to seed, it’s definitely a worthwhile experience.

Seeds develop after a male cannabis plant pollinates a female. Only female plants produce seeds
Growing Cannabis Seeds: Here's Everything You Need … – Herb
Growing Cannabis Seeds: Here’s Everything You Need To KnowStarting cannabis from seed can be extremely rewarding. Not only do you get to take your plants through a complete growth cycle, but you might also get to produce some seeds of your own. With seeds, anyone can go from a cannabis enthusiast to an amateur breeder.You’ll be able to custom tailor your plants to meet your specific needs or possibly develop a new strain or two. To help you experience the wonders of seeds, we’ve created this article – the ultimate guide to growing cannabis seeds.What Are Cannabis SeedsCannabis seeds are obviously the seeds of our favorite herb, but can you grow any old seed into a flowering weed plant? The important thing for successfully growing cannabis is to only cultivate female plants. Female plants will provide you with the highest quality flowers for smoking. However, those same female plants should be seedless, so where do cannabis seeds come from?Cannabis seeds are produced when a male plant fertilizes a female plant. You don’t want this to happen if you’re growing females for smokable flower because then the buds are cluttered with seeds. That’s why cultivators isolate their female plants as soon as they identify the sex, and you should too.Of course, if seeds are desirable for reproduction or hemp seed oil, then this process is allowed to happen. However, when it comes to creating cannabis seeds to produce a new generation of plants, there are some other techniques experienced cultivators will use.How To Find And Choose The Right Cannabis SeedsIf you’re growing from a clone, it’s unlikely that your plant will produce seeds. Seeds develop after a male cannabis plant pollinates a female. Only female plants produce seeds. Yet, when you smoke cannabis, you’re typically smoking the unfertilized bud of the female flower. This can make it a bit difficult to actually find seeds if you’re interested in growing from scratch.There are a couple of ways you can source your seeds. If you live in a legal medical or recreational state, ask your favorite dispensary for reputable local seed companies. Many people also order seeds from online seedbanks such as ILGM. Though, this is illegal in the United States. Seeds for “souvenir purposes” are legal in many regions around the world, allowing many seedbanks to ship worldwide.Though ordering seeds is illegal in the U.S. and you can face criminal charges, seed arrests are uncommon in comparison to arrests from growing or germinating plants. It’s not uncommon, however, to have your mail-ordered seeds confiscated by U.S. customs. If you order seeds from an international seed bank and they are found, you will get a letter in the mail saying that your seeds have been tossed out.Do All Cannabis Plants Produce Seeds?Cannabis plants only produce seeds after a male plant pollinates a female plant. It’s uncommon to find seeds in dispensary quality bud, and it’s also unlikely that your plants will develop seeds if you’re growing from a clone. When you smoke or vape marijuana, you’re typically consuming the unpollinated, seedless female flower. This part of the plant is named sinsemilla, meaning “without seed”.Female plants produce significantly more resin than male plants, which is why bud from female flowers is what we’ve come to cultivate for harvest. Marijuana resin in the form of trichomes produces has a crucial role in the plant’s reproductive cycle.The trichome-heavy female marijuana bud is designed to capture male pollen spores in order to develop seeds and reproduce. When females are kept away from the males, not do you create sensimillia, but you also kickstart trichome production.So, while all female plants are capable of producing seeds, pollination is required for their development. Breeders and seed banks play the part of geneticists and help spur evolution by selectively mixing pollen from specific male plants with the genes from selected female plants. This creates seeds featuring hand-selected and carefully chosen traits.How To Choose Your SeedsLook For These TraitsFinding seeds may be a little tricky, but choosing the right seeds to grow is easy. There are a few qualities that set good seeds apart. When you’re picking out your seeds, watch for these…
Where Are Marijuana Seeds On The Plant?
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%. You could also find our FAQ Submission How Many Marijuana Seeds To Grow A Plant? useful
Marijuana's History: How One Plant Spread Through the World
Marijuana’s History: How One Plant Spread Through the World Home News (Image credit: Triff/Shutterstock.com) 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…
Why am I seeing seeds in the buds of my cannabis plants?
Why am I seeing seeds in the buds of my cannabis plants? All Q&A Cannabis I have an indoor growroom and in my recent harvest I found seeds in the buds, but I’m sure there are no male plants in the room. I’ve heard that light leakage can cause plants to become hermaphrodites. Is this true, and if so, do you have any tips for avoiding this? Cannabis plants are monecious. This means they have the ability to be either male or female. Or in the case of hermaphroditism, they can be both. The reason to make sure there are no males or hermaphrodites in your garden is because male flowers make pollen. When pollen touches the white hairs on a flower, it makes a seed, and seeded weed gives you headaches. Even though there are reasons in nature hermaphroditism could be important, such as continuing the species in case there is no male present, hermaphroditism is generally a bad thing when talking about cannabis plants.Light poisoning is the most common cause for a normal plant to hermaphrodite.Light poisoning refers to the flowering night cycle of a plant being unnaturally interrupted with light. The best way to prevent this is to close yourself inside your darkened room during the daylight, and then after allowing a few minutes for your eyes to adjust to the dark, check for any light leaks from covered windows, door jams, etc. Also cover all timer and appliance lights with tape.Negative stressors can combine with small interruptions of the light cycle to cause hermaphroditism, especially with less-stable, clone-only hybridized strains. When the night cycle is abnormally interrupted, it sends a mixed hormonal signal to the plant. This can cause a full female plant to throw some male flowers. Male flowers are easy to identify, especially when side by side with female flowers. Male flowers look like small bunches of bananas, which will take a week or two to swell before they burst and release their pollen.Read also:Are Cannabis Plants Monecious or Dioecious?Anatomy of a Cannabis PlantUltimate Seed Feminizer: Colloidal SilverFinding a hermaphrodite in your growroom can happen at any stage of the flowering cycle and is indicated by the presence of male flowers growing on the same plant as female flowers. As with all species in nature this can occur in varying degrees. A plant can become slightly or majorly hermaphroditic. In cases where singular male flowers are found between the branch and stalk nodes, you should be diligently removing them as they grow. You must re-inspect the plant top to bottom every few days to be sure pollination and seeding doesn’t occur. If you find male flowers (anthers) actually growing from within the female flowers (buds) the situation is a little more dire. You can still remove all the male anatomy as it appears, but it will be harder to find and much more prevalent. This is a horrible discovery that leads to a tough decision: Should you let the plant live and risk the whole crop being ruined by seeds?In either case, once hermaphroditism has compromised the safety…

How do Cannabis Seeds Work – GB, The Green Brand
How do Cannabis Seeds Work – GB, The Green Brand How do cannabis seeds work? You might not think that this is important, but knowing how seeds work can give you important insight on how to store them and what the germination profess involved. Cannabis seeds are technically small, oval-shaped dried fruit, around 3-4mm long and 1.5-2mm wide. They’re covered in a very subtle membrane, and underneath that layer there’s a much harder layer which is the largest system of the embryo, covering it and protecting it. On the inside of the seeds you can find a substance called albumen, which is a nutritional reserve that keeps the embryo healthy until germination; it’s also the seeds initial source of energy once it begins germinating. Now, for the center of the seed, home to the precious embryo from which your new plant will grow from. It contains the plant’s genetic code alongside four other parts; the radicle, the hypocotyl, cotyledons and gemmules. The radicle is the embryonic root; this is the part of the seed where roots come from. The hypocotyl is known as the embryonic stage, and the cotyledons are in charge of those first few leaves that you can see once the seed germinates. Cannabis seeds, just like many other plant seeds, grow in pollinated flowers on female plants; seeds only contain the plant’s genetic code, so they don’t have any of the active principals in the plant, meaning that if you were to smoke it you wouldn’t get any sort of psychoactive or medicinal effect. They can be eaten however, as they provide an enormous amount of beneficial proteins, including Omega 3, 6 and 9. The aroma that comes from the seeds when burning isn’t pleasant at all, and if you’ve ever been smoking a joint that had a random seed in it then you know exactly what I’m talking about; they taste like some sort of burnt barbecue that ruins the taste of even the best, strongest tasting weed out there. Germinating seeds correctly depends on different factors; the main one being how mature the seed is. Seeds that look too white, green or the skin seems to be coming off or not there at all tend to be too young still, although there are seeds of this stature that will germinate perfectly, depending on the strain. Strains like Somango, or hybrids that come from it, and Haze seeds are some of the whitest seeds you can find on the market; sativa seeds tend to be much smaller than indica seeds, like Thai seeds are generally much smaller than afghan seeds. In this case, size doesn’t matter at all; if a seed is smaller than others that doesn’t mean that it’s going to have issues germinating or that it will grow smaller plants. Smaller seeds generally have less protection, but they’re much easier to germinate. Seeds can take between 3-18 days to germinate depending on the conditions such as temperature, humidity, substrate composition etc. The longer the seeds take to germinate, the less likely that they are going to germinate. Sometimes if after a while it still hasn’t germinated, you can gently squeeze the seed to break the outer shell and if done right, you can help the root to leave the shell; if done wrong, you’ll end up completely squishing the seed and any chances of germination that it had. During the time the seed is maturing various factors need to occur for the seed to be able to germinate in the best conditions. Seeds have a germination period of three years, which is the average time estimated that seeds can be kept in good conditions; it’s not the same to keep your seed in a fresh, dry area than in a hot and humid one. Humid areas will damage seeds, stimulating their metabolism with the humidity without stimulating germination which could even kill the seed off entirely. Water absorption is due to the water potential difference between the seed and its surroundings. Water reaches the embryo through all of the layers of the seed, which then activates the development of the radicle; once this process begins, seeds need more oxygen than water, so giving…
What are Cannabis Seeds? Marijuana Seed Definition
Cannabis seeds 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. Cannabis seeds are brown and about the size of a peppercorn.Photo by: Gina Coleman/Weedmaps 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. Photo by: Illustration by Weedmaps 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. Seedless cannabis 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…
