Cannabis Seed Identification Guide: distinguishing viable seeds from non-viable seeds before planting
Strong, high quality cannabis seeds will ensure a high quality cannabis plant. So, if and how is it possible to identify whether cannabis seeds are good or not? And how long do these seeds retain their vitality? Answers on seed identification:
Identification of a seed
Most of the cannabis seeds offered for sale in seed shops are of high quality. In most cases, they exhibit high germination rates of at least 95% and sometimes even higher . On the other hand, seeds from an unknown source may well be defective and eventually lead to the growth of a weak and disease-prone plant with slow growth rate and low harvest potential.
You can tell a lot about the health of a seed by looking at it. Here are a few different things you should look for when deciding whether a cannabis seed is good or not.
Good cannabis seeds will be brown, black and / or gray. White or green seeds are immature and unlikely to germinate. Your seed should also have scratches or spots all around.
A healthy seed will have a thin waxy coating around it. This coating seems to have a slight shine.
You should be able to lightly squeeze a seed without crushing. If a seed crushes easily between your fingers, the seed is probably dead or weak and will not grow well.
Inspect the entire seed to make sure there are no small cracks or holes. This will likely cause the seeds to not sprout.
Means of testing cannabis seeds
You have a basic guide to distinguish good from bad seeds. Now if the doubt persists, here are several ways to test the seeds.
Test method No.1: seeds floating in water
It’s a great test that works for many different seeds – and not just cannabis. Take your seeds and drop them in a cup full of hot water (not too hot) then wait a few hours. If they sink, they are probably good for a crop. If they don’t leak, they’re probably dead and won’t grow.
Note: Do this only if you are ready to germinate your plants. Otherwise, it could hurt your seed.
2 test method: just before and try to sprout the seed
I know it sounds obvious, but it really is the best information .
If you really want to know if a cannabis seed is capable of germinating, put it in the ground .
How to sprout a cannabis seed
This is the first step in the journey from your cannabis nursery to a whole plant. There are several ways to do this. One of the ways is to just plant it in your soil and see if a plant appears. It’s old school, but no one can deny its simplicity. Plant the seed about 1/4 “(inch) deep and wait.
Another way is to put the seeds on a damp paper towel. Make sure the paper towel is damp, but not too wet… If it gets dry, you can add a few drops of water to the paper towel. Leave the paper towel in a dark place. Remember that the time varies between strains. Some may take just 2 days, while others may take longer… Keep checking them once a day.
Male or female ?
Unfortunately, there is no way of knowing if a cannabis seed is going to be male or female. And just by looking at it or doing a simple test.
If you want feminized seeds, you will need to buy them from a reputable seed bank. Make sure they say they are “feminized” – if they don’t, the seeds probably won’t, or rather randomly. These are the so-called “regular” seeds
If all you get is a bag seed, the only way to know if it’s going to be male or female is to develop it.
The seeds have an expiration date. But if you store your seeds properly, they can remain viable for years and years. Moisture, UV degradation and extreme temperatures could affect the quality of your seeds.
If you plan to store your seeds for a long time, be sure to keep them in an airtight container in a dark area. Ideally, seeds should be stored in an air-conditioned area (such as inside your home rather than in a shed or garage). A survey shows that cannabis seeds sealed in the laboratory were still viable after 19 years.
It’s nice to know what to look for, but in the end the best test is just to put it in the ground.
If you are using seed bags you never really know what you will get anyway. If you bought your seeds from a seed bank, you shouldn’t worry about it.
How to Identify a Female Marijuana Seed
Ask any experienced grower how to produce a hardy marijuana plant and they will say to start with a seed for a good strain. Lighting, soil, nutrients, and water play large roles in the final yield, but starting with a high-quality seed gives growers the best genetics with the highest potential yield possible. Most people find their first seed mixed in with marijuana, but most of these seeds are low quality and may grow to be male plants. The best way to get high-quality seeds is to purchase them from a reputable marijuana seed retailer.
Characteristics of a Quality Marijuana Seed
Quality marijuana seeds have specific characteristics that set them apart. Unfortunately, they can be difficult for consumers to find since most growers avoid seed production in their plants at all costs. Even when a rogue seed is present, it rarely grows mature enough to germinate. Though it is challenging to identify a quality seed for even the most experienced growers, it is vital to be able to do so when using seeds to grow marijuana. Below is an overview of the characteristics of a high-quality seed.
There are several visual indicators that can give a person an idea about the quality of a marijuana seed. Some details are easy to spot while others take a higher level of scrutiny.
A high-quality marijuana seed has a dark color, typically a shade of brown, grey, or black. It should have tiger-like stripes or spots on the entire surface of the seed. If the seed is green or white, it is immature and is not likely to germinate. In the rare circumstance that an immature seed germinates, it takes much longer than it would for a mature seed.
Good quality marijuana seeds have a waxy coating around the shell. This is easy to see if the seed is held up to the light because the shell will have a slight sheen.
Size & Shape
The largest seeds are the best ones to grow. It is easier to pick the largest ones if there are several to compare side by side. Growers should look for the most symmetrical seed that is round or shaped slightly like a teardrop. Underdeveloped seeds are small and have an asymmetrical shape.
A lot of information can be gleaned from the texture and hardness of a marijuana seed. After visually inspecting the seeds, growers can pick them up and feel their shell for the following:
Poor quality seeds have weak shells that are damaged easily. These seeds will have cracks or splits on them that expose the inside. The best seeds have a smooth exterior with few anomalies.
A mature, high-quality marijuana seed has a hard shell that can withstand the pressure of being squeezed between two fingers. Poor quality seeds will disintegrate when squeezed. If this happens, the seed was weak or dead and would not have grown a viable plant if it germinated at all.
How to Determine the Quality of a Marijuana Seed
While seeing and feeling a marijuana seed can give growers a lot of information, it is not always accurate. Even the best-looking seeds can be duds, especially if they have been frozen. Below are a few things growers can do to better determine the quality of their seeds.
Germinate the Seed
The most obvious thing a person can do to show seed quality is to germinate the seed. If the seed sprouts within 5 days, it is a viable seed. It will still take time to find out if the plant will be male or female and whether the strain is high quality.
How to Germinate a Marijuana Seed
The traditional way to germinate a seed is to bury it one-quarter inch deep in moist soil and watch it closely for a sprout. A freshly germinated seed has a very fragile root that is easily damaged when the seed is transplanted. This method allows the seed to germinate without root interference.
Another common way to germinate marijuana seeds is by wetting a folded paper towel or cotton pad and placing the seeds inside of it. It is important not to get the paper towel or cotton pad too wet or it could drown the seeds. Growers should check the seeds after a few days to see which have taken root.
Perform a Float Test
The float test is a more scientific approach to determining the quality of a seed. The test involves filling a drinking glass with spring or distilled water and placing the seeds inside of it. Allow the seeds to soak for one to two hours before determining quality.
After the time has passed, seeds that float can be considered poor quality and discarded. Seeds that have sunk to the bottom of the glass are healthy, high-quality seeds. Once the test is complete, the seeds need to be germinated right away. Their shells will be soft from soaking in the water and will not survive storage.
Source Them Well
The simplest way for growers to ensure they have high-quality seeds is by sourcing them from a reputable seed bank. These companies specialize in breeding a variety of marijuana strains and producing seeds that, with the right care, grow into viable, high-yielding plants. Growers can choose a variety that meets their requirements for potency and desired effects and be sure they are getting seeds that produce the plant they want.
Using an Online Marijuana Seed Bank
Those who live in a state where marijuana is legal for medical or recreational use can sometimes find seeds at their local dispensary. However, online marijuana seed banks have significantly more strains available. Even individuals who live in some states where marijuana has not been made legal to use can purchase seeds online. Several states consider dormant seeds to be souvenirs, so it is legal to purchase and own the seeds as long as they don’t become high-THC plants.
Do Marijuana Seeds Expire?
Many growers who have numerous marijuana seeds need to store them long term if they want to germinate them in the future. However, seeds need to be kept in specific conditions to remain viable. They should be stored in a cool, dark, and dry room, much like the environment in which growers dry their harvested marijuana.
Germinating Old Seeds
Seeds can remain viable for three to ten years if stored properly, but more and more seeds will fail to germinate as time passes. Older seeds will take more time to germinate, so growers should use the float test before assuming the viability of their stored seeds. They can speed germination by soaking the viable seeds in water mixed with a few drops of hydrogen peroxide for 24 hours. It is important to watch them closely for signs of opening, as they will need to be removed immediately to avoid drowning.
Can You Tell if a Marijuana Seed is Female?
Cannabis enthusiasts have been trying to find out how to determine the sex of a marijuana plant by the seed for ages. Unfortunately, there is no way to tell if the seed will produce a male or female plant by just looking at the seed. Regular marijuana seeds have a 50% chance of being female, so out ten seeds, growers can expect that 5 of them will probably produce female plants.
What Does a Male Cannabis Plant Look Like?
When growing marijuana, it is important to identify male plants as early as possible. Just one male plant can pollinate an entire field, so it is critical that male plants are removed before they develop pollen sacs. There are certain signs that a young marijuana plant is male, including the following:
Preflowers are the earliest sign of a marijuana plant’s gender. Between four and six weeks, nodes will develop at the joint where a plant’s stem meets the stalk. Female plants develop white hairs at the internodal joints while male plants develop rounded internodal sacs that fill with pollen.
While it is best to identify male marijuana plants by their pollen sacs as soon as possible to avoid accidental pollination, there is another way to determine a plant’s sex. If male and female seeds are planted at the same time, the male plants will grow faster and taller than the female plants. Additionally, male plants have longer stems with fewer leaves, making them look spindly compared to female plants.
Quality seeds are not often found in the bottom of a bag of dried marijuana, but there are ways for growers to ensure they are getting the best seeds available. With a keen eye and a reputable seed bank like i49.net, growers will have hardy, high-yield plants that make them proud of their hard work. Seed banks provide quality marijuana seeds in a variety of strains not typically available from other sources, and many of them can guarantee that the seeds will be feminized and thus produce female plants.

Recognize quality marijuana seeds
Marijuana is best known for its effects on people when they smoke it. So, where does this high effect come from?
How do you ensure that the quality of your marijuana is as good as it could be? It all starts by choosing the right seeds. The right seeds are mature cannabis seeds.
Understand how to recognize quality marijuana seeds before you can grow the best marijuana. High-quality cannabis starts with good genetics.
Begin your grow with healthy, mature cannabis seeds from a reputable seed bank.
When you have a particularly good strain or good season of marijuana growth, you will most likely want to store seeds for that particular type of cannabis, its “parent plant,” so you can experience the same sort of success later on.
In this article, we will cover the basics of selecting the right seeds.
About quality marijuana seeds
How to grow the best weed
To grow the best weed, you need to know what determines the best seeds, why genetics make certain weed plants better than others, and how to choose the best seeds.
THC, a term that usually refers to Delta-9 tetrahydrocannabinol, is the ingredient in marijuana that is the primary contributor to the high feeling smokers experience.
This is a bit misleading for two reasons.
First, some types of THC are not Delta-9, such as Delta-8. Second, THC is not the only chemical that is responsible for a high.
Other compounds contribute to the feeling – these chemicals are called cannabinoids.
Cannabinoids include every different variation of THC, and they make up the psychoactive ingredients that lead to the feeling of being high.
The tricky thing about marijuana is that no one can really define the right combination to achieve the best or greatest high.
Even scientists are unable to figure out what combination of cannabinoids makes the most potent combination.
This is partly because the feeling of “high” experienced from marijuana cannot be measured externally – it can only be described by the person experiencing it.
This makes any evidence about correlations between different combinations of chemicals and types or strength of highs very subjective.

The experience is also different for each person, even if they take the same amount of the same plant as someone else.
Any mix of emotions (usually euphoria, elation, paranoia, sleepiness, or clarity of thought) can be felt by different people, even if they consume the same amount and type of weed.
The best weed comes from the best genes
While there is still a large amount of variation from seed to seed, even within the same strain, a lot depends on the environment in which it is grown and the care you have when raising your plants.
Growing your own weed is an extremely gratifying experience. It will take a bit of trial and error, and you will have to overcome some inevitable failures, but it will be even more rewarding when you finally succeed.

The source always matters
You can source your seeds from:
- A bag of weed
- A seasoned grower
- A seedbank
The first step for most new growers is to extract seeds from large commercially purchased bags of cannabis.
This is likely the easiest way to get seeds but take caution— that cannabis has already been heavily processed and packaged.
Huge quantities of bud are dried and cured together en masse and then snipped and stuffed into big vacuum-sealed bags.
Unless you are already directly familiar with the mature plants your seeds or clones came from, growing marijuana is unavoidably unpredictable.
This is why it is especially important to seed or clone your best quality plant since that will make you able to guarantee the quality of the next crop.
Knowledge of the source is also why experienced growers have better outcomes with their harvest.
They often choose their best cannabis plants out of a single strain, and use those seeds for the following season’s harvest. Now, they have a better understanding of the plant their seeds came from and can also improve their care of the same type of plant.
Aren’t seeds a bad thing?
All cannabis cultivation comes down to your goals as a grower. Want a bountiful harvest? You’ll want to grow the best weed by breeding perfection using seeds. Skip ahead to learn why.
“Nope, I want to smoke,” then you need to grow plants that produce fewer seeds. You need feminized seeds.
“Sinsemilla” is a Spanish word that translates to “without seed.”
It describes female cannabis plants that grow into maturity without fertilization from male pollen. Growing sinsemilla marijuana outside is almost impossible since your female plants could be pollinated from the male plants up to a mile away!
So why do you want to avoid pollinating your female marijuana plants? Pollination means that the plants will use their precious energy to create seeds instead of flowers.
This is due to natural selection. Since a plant that produces more seeds is more likely to reproduce, a female marijuana plant will prioritize making seeds if fertilized.
Although this is an advantageous feature for marijuana’s survival, it is not exactly what smokers look for in a weed plant.
Sinsemilla marijuana, having never been pollinated, usually produces a more resinous bud since there are no seeds to take over the valuable flowering area.
Producing seeds isn’t all bad for the smoker, however. If one crop is particularly delicious or potent, it is vital to let those plants produce some seeds.
Store these seeds correctly and label them accurately to make informed decisions about which seeds produced the best crop and which ones are better to avoid.
You can then use seeds that produce tall plants or strong, sweet buds for a future growing season.
When you find a plant that you want to preserve seeds for, make sure to treat those seeds with extra special care, as they are your best bet for harvesting the best product.
Why you should grow weed from seeds
Some people are intimidated by growing marijuana from seeds. At first, the results may not be as big as you had planned for – this is normal, and you will continue to get better with time and experience.
To reach the highest possible yield of cannabis, you must study and practice, especially if you haven’t done anything so much as growing potted house plants or flowers on your window sill.
Just keep at it, and within a few growing seasons, you will be an expert.
Although research and preparation make a big difference, they can only go so far without actual hands-on experience.
As you learn and develop your skills, trying clones may be tempting rather than learning by trial and error with seeds. Careful, though.
Different strains and plants will grow, mature, and flower at different rates. Growing one Sativa might be completely different than growing a different strain of Sativa.
Plus, you never know what you may end up growing. When growing from clones from another grower, your clone might inherit any issues they had while growing it.
Buying marijuana seeds from a seed bank
Buying seeds from a seed bank gives you a better idea of what to expect in terms of the quality, yields, look, and time it will take to bloom.
Plus, you’re starting fresh with new seeds, which lowers the risk of diseases or pests in your plants. Learn more about why growing from seeds produces the best weed.
When you grow from seeds you have certainty. Whenever you see your stash of weed in the freezer, you will feel proud.
Whenever you smoke your marijuana, you can feel safe and satisfied because you know exactly what you are putting into your body and where it came from.
Where to find the best quality seeds
Quality marijuana seeds mean quality genes. Better genes better your chances of growing a healthy harvest.
Online seed banks offer a wide selection of quality marijuana seeds, and reputable seed banks make it easier to purchase good seeds.
Your seeds should come from seedbanks because the ones that sneak into dried marijuana flowers are rarely usable – mostly because they never reach full maturity before being harvested.
