cannabis seed identification

If you are still unsure about the quality of your seeds after analysing their appearance and toughness, it’s time to put your lab coat and goggles on. Well, not quite. This test is extremely easy and only has two possible outcomes. Fill up a drinking glass or glass jar with water (preferably spring or distilled) and place your seeds on the surface.

Cannabis Seed Quality: What To Know Before You Grow

Are your seeds light or dark in colour? Are they tough under pressure or do they turn to dust? These are some of the ways to tell if your seed is healthy and worth growing.

One of the keys to achieving healthy and vigorous cannabis plants is starting with high-quality seeds. Of course, prime nutrients, adequate watering, and good light quality all contribute to the final yield obtained. But starting a grow with tip-top genetics is equally, if not more important. Carefully sourcing high-quality cannabis seeds will ensure you are receiving the exact genetics you are looking for. Not only will they provide you with the desired cannabinoid and terpene profiles, they will help you to avoid dud seeds.

There are several factors to look for when purchasing seeds, and certain signs that signify the seed isn’t worth the time and effort.

APPEARANCE AND FEEL

One good way to gauge the quality and traits of a cannabis seed is to get used to how they look. Some details are glaringly obvious, whilst others take some time to identify quickly. Healthier and genetically superior seeds will exhibit darker colours on the outer shell. Shades of grey and black are signs of a good seed, sometimes displaying a tiger stripe aesthetic.

Healthy seeds will also look as though they have a coating of wax of their shell. This can be made obvious when exposing them to a bright light and witnessing a sheen effect.

Darker and better-quality seeds will feel firm to the touch. Place the seed between your thumb and index finger and give it a squeeze, not enough power to bend metal, but enough to tests its resilience. If the seed feels firm and does not bend or break under the applied pressure, then it’s more than likely worth planting.

Poor-quality or old seeds will crack and crumble under pressure. If they break into parts under slight pressure, they will be unusable. But they wouldn’t have been worth the time anyway. Seeds are simply pods of a plant genetics. With time, they will age and become unusable. Seeds that are obviously past their prime are not worth wasting time on.

Immature and young seeds will be green and white in appearance. It is unlikely that these seeds will germinate, and if they manage to, it will just take longer. It is worth obtaining fresh seeds that are of optimal age.

SEEDS FROM A BAG

Some smokers might be pleased to see some cannabis seeds in their bag, and might think themselves lucky. However, finding seeds in a bag is bad for various reasons. For one, this means the grower has messed up and allowed their female plants to be pollinated by an invading male. When flowers are pollinated, they stop producing THC-containing resin and divert their energy toward producing seeds. Secondly, the seeds will have added to the overall weight of the bag, which means less weed for your buck.

With this said, you may get lucky if the strain they were growing really is prime. In this case, it’s worth carrying out the following test to see if it’s worth germinating.

GERMINATE THEM REGARDLESS

The one true method to test the genetic potential of a seed is to simply put it in the soil. It won’t take too long to see the results. This option is best for the hobby home grower who has time and space to spare for a risky project. Growers cultivating cannabis for commercial use likely don’t have the excess time to invest.

SOURCE WELL

A solid way to obtain great seeds is to find a reputable seed bank. These companies pride themselves of their breeding skills and make sure that their customers receive exactly what has been advertised. They have reputations to cater to, so delivering anything less would only harm their image.

The alternative to this is to risk buying seeds from a hobbyist. This isn’t to say that hobby growers cannot produce fantastic genetics, but if you don’t know them or their skills, there’s no way to know whether your seeds will grow.

CONDUCT THE FLOAT TEST

If you are still unsure about the quality of your seeds after analysing their appearance and toughness, it’s time to put your lab coat and goggles on. Well, not quite. This test is extremely easy and only has two possible outcomes. Fill up a drinking glass or glass jar with water (preferably spring or distilled) and place your seeds on the surface.

This simple and cost-effective method is a great way to tell the good genetics from the bad; they will sink or swim, literally. Seeds that remain buoyant on the surface are more than likely of poor quality and are to be discarded. Seeds that sink to the bottom like a botanical cannonball are probably healthy and should be germinated.

However, slight patience is required when conducting the float test, as results are not immediately apparent. You’ll have to wait for approximately 1–2 hours before confirming the results. Some good-quality seeds will need adequate time to absorb enough water for them to sink. Use this time to go water the garden and get some much needed pruning done. Upon your return, any seeds that remain on the surface are most likely not viable and won’t be worth further time and effort.

It’s important to only conduct this test if you are planning to germinate the seeds immediately afterwards. The viable seeds that sunk to the bottom of the glass will have taken in water, crossing the membrane of the seed and signalling that it’s time to come to life—activating germination.

I know it sounds obvious, but it’s really the best information .

Seed identification guide before planting

Cannabis Seed >High quality, 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 about seed identification:

Most of the cannabis seeds offered for sale in seed stores are of high quality. In most cases, they have high germination rates of at least 95% and sometimes even higher . On the other hand, the seeds of an unknown source may well be defective and eventually lead to the growth of a 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 some different things you should look for when deciding whether a cannabis seed is good or not.

Dark color

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.

Waxy coating

A healthy seed will have a thin waxy coating around it. This coating seems to have a slight shine.

Hard shell

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.

No cracks

Inspect the entire seed to make sure there are no small cracks or holes. This will probably cause the seeds to not grow.

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: Floating seeds in water

It’s an excellent test that works for many different seeds – not just cannabis. Take your seeds and put them in a cup full of hot water (not too hot) and wait a few hours. If they flow, they are probably good for a crop. If they do not flow, they are probably dead and will not 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’s really the best information .

If you really want to know if a cannabis seed is able to germinate, 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 many ways to do this. One of the ways is to simply 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 wet paper towel. Make sure the paper towel is moist, but not too much . If it dries, you can add a few drops of water to the paper towel. Leave the paper towel in a dark place. Remember that time varies between strains. Some may take only 2 days, while others may take longer . Keep checking once a day.

Male or female ?

Unfortunately, there is no way to know if a cannabis seed is going to be male or female. And just by looking at her or doing a simple test.

If you want feminized seeds, you will have to buy them from a reputable seed bank. Make sure they say “feminized” – if they do not say it, the seeds will probably not be, or randomly enough. Are the seeds called “regular”

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.

expiration

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, the 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.

Conclusion

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 use seed bags, you never really know what you will get anyway. If you bought your seeds at a seed bank, you should not worry about it.

If you are still unsure about the quality of your seeds after analysing their appearance and toughness, it’s time to put your lab coat and goggles on.

What does the appearance of a cannabis seed indicate?

Can the visual appearance of a cannabis seed indicate anything useful about the future plant which it will produce? It’s a question which has been asked by many cannabis growers. And over the years there have been many different theories about this.

Cannabis seed weight. What does the weight of a cannabis seed indicate?

Dutch Passion created feminized seeds in the 1990’s. It was a revolution for cannabis growers. But in the days before feminized seeds, some people felt that ‘male’ and ‘female’ seeds could be separated according to their weight, appearance, size, shape etc. The idea behind this unproven theory was that cannabis seeds all had different sizes and shapes for a reason. One of the first difficulties with the theory is that different marijuana seed varieties often produce different size seeds. White Widow seeds, for example, can often look smaller than other varieties. And yet they produce excellent quality harvests. Seed size has no relationship to potency. The future sex of a cannabis plant simply can’t be determined by the weight or size of the cannabis seed. If it were that easy the seed companies wouldn’t spend as much time and effort to create feminized seeds.

Feminized seeds vs autoflowering seeds. Do they look different?

Every so often a home grower will accidentally mix up their seeds. Often this is done after a smoke/vape, perhaps when you are getting the cannabis seeds ready for germination. If you have ever mixed up your seeds it can feel impossible to be confident about their true identity. There is no certain way to distinguish between feminized seeds and autoflower seeds just by looking at them. The plants real future identity lies in the DNA inside the cells within the seed.

Stripes on cannabis seeds. What do they indicate?

Cannabis seeds have an undeniable beauty and appeal. The various shades of brown are delicate. Under powerful magnification you can see how a cannabis seed is a wonderful piece of natural beauty and design. When you examine a cannabis seed near a bright light you can see a shiny reflection, as if the seed has a coating of wax. Not every cannabis seed has a similar appearance to the next. Some seeds will have dramatic tiger stripes. Others will have a more homogenous surface coloration. The appearance of the seed isn’t a reliable indicator of any particular plant quality. Everything is coded in the genetics inside the plant tissue safely encased inside the shell. From the sex of the plant to the cannabinoid and terpene profile, plant DNA and genetics determine the future. That’s where you rely on the seed company doing their job properly. The highest quality cannabis seeds are not always the cheapest. But if you buy from a company with a reputation for quality you know that a great deal of skill and effort, and many years work, has gone into your cannabis seeds.

Are heavier cannabis seeds more difficult to germinate?

Some growers feel that the largest seeds can be more difficult to germinate due to the extra shell material. However, the shell material is designed to be weakened by water, it shouldn’t really be an obstacle to germination rates. As the fibres in the shell are penetrated by water, the shell structure swells and weakens allowing the tap root to emerge. Poor germination rates of cannabis seeds is often a sign of old seeds. It could also be the result of poor quality seed production practices. This is one area where established seed companies have the benefit of many decades of know-how and experience. Cannabis seed production is just like any other intricate and highly skilled process. The most experienced seed companies have people who are at the top of their profession with several decades of practical knowledge producing the best quality cannabis seeds. Dutch Passion do not recommend the use of sand paper to reduce the thickness of the cannabis shell. It’s too easy to accidentally damage the inner seed. Simply leave the seed to soak in a damp paper towel for a day or so. But never try to force open the seed, or use artificial abrasion techniques to try to weaken the shell.

Old cannabis seeds

Very old cannabis seeds feel weaker when gently squeezed. In the worst cases the shells crack easily and the powdery crushed contents are released. The best way to store cannabis seeds is in a dry, dark container in a cool place such as a fridge. Cannabis seeds will still have good germination rates after several years of cold (and dry) storage.

Immature cannabis seeds

Cannabis seeds which were harvested too early will have a green/whitish appearance. Often these will be small in size, and will struggle to germinate. Seeds that are clearly immature are not recommended for growing. Some seeds, such as Dutch Passion Frisian Duck, can have their own coloration. In the case of Frisian Duck the seeds have a slightly unusual grey appearance

Buy the best cannabis seeds online

The best way to achieve a good quality harvest of home grown cannabis is to invest in some high quality seeds. Buying cannabis seeds online from a high quality seed company guarantees fresh seeds with good germination viability. You also benefit from the security of knowing that your cannabis seeds contain the best genetics to deliver top quality cannabis at harvest.

I revently bought a 5 pack of feminized Skunk #11 and the seeds are tiny and white and look very immature. Im trying to germinate one right now but Im not confident it will sprout, should I worry?

Through the years I myself have grown just about every any seeds I have run across and In my experiences a. Male is a male and a female is a female.until you are ready to start budding you just won’t know.also have planted some texmex dirt seeds and produced some of the best Bud I’ve ever smoked

I tried pots and many mediums but the best and quickest way I find is in a glass of tepid water, this will also show if your seed is fertile and will sprout. first get a small dark glass I use a brown pill bottle or tub. First fill 3/4 of your water vessel with tepid water. Get a seed or seeds and pop in. Now don’t panic if they float. After 2 hour if seed is floating just lightly push seed under water a few times if needed. If still floating leave for another 2 hours or overnight. You can put lid on pill jar or clingfilm to ensure you vessel is air tight. Place in a dark warm place for 24hours. Your seed should be sprouted. Thank out seed sandwich between Wet paper towel on a plate and leave back to same warm spot and ensure to keep moist..Your sprouts should be good to go in a total of 3-4 days. Best of luck Aido

2″ container filled with potting soil,1″deep where seed won’t corkscrew out,water,3 days sprouted. No muss no fuss.

antony stewart

A rule of thumb for gardeners is that a seed should be 1-2 times as deep as it is big. a pea at 2cm, a ganja seed at >1cm.

Hi Alf ! After 35 years of starting my seeds using fine, sieved soil in small plastic pots, last year I tried small Rockwool cubes (40 x 40 x 40 millimetres) for germinating my babies. This was extremely easy and I achieved 100% germination. It will now be the method I use for the rest of my days, so pleased was I with the results and how simple it is ! I plant my seeds pointy end down, one seed per cube. There is no need to pre-treat the seeds in any way or do any other various types of physical manipulation; the plants have been doing it themselves, unaided, for Millennia ! Start by soaking the cubes in a bucket of room temperature, aged / chlorine free, clean water for a few minutes, then remove the cubes and give them a couple of quick flicks in a downward direction to remove the excess water. I then make a small hole in the cube, about the same width of the seed and roughly twice as deep as its’ size, with a small pointed stick. After inserting the seed (a small bamboo skewer can be very helpful), I use a small “fluffy” piece of Rockwool, about 2-3 times the size of the hole and about 2-3 millimetres (1/8 of an inch) thick, taken from either the edge of the cube or another cube especially sacrificed for this purpose and cover the seed in its’ hole lightly, with this small tuft / fluffy piece, so it forms sort of a “hat” and very gently give the “hat” a pat so that it is in contact with the rest of the cube. There is no need to push the “hat” down hard. After this I use a water spray bottle (atomiser), with the nozzle adjusted to a misting setting, to lightly moisten the “hat”. Again, using clean, room temperature and chlorine free water. After all this, I place the cubes onto a saucer that has some very fine aquarium gravel or a similar substrate, covering the bottom (of the saucer). This is to provide air circulation and drainage, in case you are too generous with watering. You need to keep the cubes moist, but NOT wet. If you can feel moisture when lightly touching the cube with the back of a finger, this is moist enough. Resist the urge to water every day (unless necessary) and under no circumstances, do not use any fertilisers. The embryonic seed has / contains all the nutrition and energy it needs for the first 2-3 days of growth (think bean sprouts!). The best way to maintain the correct moisture level is to use the water sprayer bottle and mist the cubes gently. You will, after some experience, be able to judge the moisture content by the weight of the cube when / if you pick them up. Do not let the cubes dry out, but this is highly unlikely if you check the cubes at least once a day. Keep the moist cubes in a warm shady area and away from any direct winds / breezes that may dry the cubes out prematurely. Only once the seeds have sprouted should they be placed in / under any light, but the sooner they are, the better. There is no need to cover the saucer with the cubes on it with anything, such as cling film or a plastic bag and do not place them in a mini greenhouse or any other type of enclosed container, as this can cause the seeds to rot due to the extremely high humidity. I have found that the cubes will remain moist long enough for the seeds to germinate with little to no extra watering, with the sprouts taking between 1 and 6 days to emerge; so do not give up too soon! Plant the whole cube into your growing system once the seed has sprouted and the plants’ root(s) are coming through the bottom of the cube. By starting the seeds in the cubes you avoid handling the fragile baby plants and prevent any possible risks of damaging the emerging embryonic leaves and roots. I hope this helps and most of all, happy growing!!

I like the damp folded paper towel in an unsealed plastic bag (in a dark room) method — however have discovered one important trick/fact. Roots always try to grow down, so put the seed inside a folded damp paper towel, but ensure only one layer is below the seed and the other damp layers are on top. The root will try to work its way down. If there are many layers below it, the root can get entangled and be hard to extricate without damage.

I germinated frisian duck seeds straight on top of a soil plug with halfvthe seed showing. I put three into a plastic box and then into a drawer in my garage. It took 6 days until they had sprouted to about 30mm high and shed the seed cap.

Alf, 4th June 2019. There are several equally good germination methods. Many customers prefer the idea of germinating seeds between sheets of wet kitchen paper, inside a sealable plastic bag. Good luck!
