White cannabis seeds vs dark cannabis seeds. Should cannabis seed germination and growth be affected by seed colour or seed appearance? Amsterdam Seeds Supply – Don't know yet what do cannabis seeds look like? – Cannabis cup winners Some people think that the size, weight or appearance of a cannabis seed can tell you about the type of plant it will grow into. Read on to find out more.
Dark vs white cannabis seed germination test
One common question from growers is whether white cannabis seeds or dark cannabis seeds have different germination rates. When you compare cannabis seeds you may have noticed that the seeds are rarely identical. Instead you may see a range of different sizes and colours. The differences in size, colour and appearance often produce debate among growers. Why do the cannabis seeds look different and do these differences result in slightly different growth characteristics in the plants which grow from them?
Dark vs white cannabis seeds germination
In the video below you can see a germination comparison. On the left hand side, you can see 9 white Think Different autoflowering seeds. On the right hand side there are 9 dark coloured Think Different seeds.
The autoflower seeds all came from the same batch, meaning that they were produced from the same parent genetics under the same conditions. Seeds were chosen simply on the basis of their appearance. 9 white cannabis seeds and 9 dark coloured Think Different seeds were selected. They were planted in moist (but never soaked) soil and a time lapse video was made.
Note that the white cannabis seeds on the left hand side were the first seeds to germinate, with 8 out of 9 seeds sprouting pretty quickly. In the end all 9 seeds germinated on both sides, which was a 100% score. In terms of white seeds vs dark seeds (cannabis), there was no difference in the germination rates.
Does the colour of your cannabis seeds really matter?
The time lapse video shows that the colour of your cannabis seeds doesn’t have any impact on their germination rates. The colour of the shell casing is simply not an indication of the type of genetics contained inside. Nor is the colour or appearance of the exterior of the cannabis seed a good indicator of any other property, such as the future plant sex, size or potency. Only the genetic material inside the cannabis seed really determines the types of result that you can expect.
Black cannabis seeds germination test results
The dark cannabis seeds (on the right hand side in the video) showed the same germination rate as the white cannabis seeds (left hand side). However, the white cannabis seeds appeared to germinate a little bit faster than the dark cannabis seeds.
White cannabis seeds germination test results
Can white cannabis seeds germinate? One curious result from the white vs dark seeds cannabis video was that the white cannabis seeds appeared to germinate slightly faster than the dark cannabis seeds. This is interesting, since the seeds all contain the same Think Different autoflowering genetics from a recent cannabis seed batch.
One suggestion is that the white cannabis seeds may have a slightly softer shell, allowing the white cannabis seeds a slightly faster germination. The experiment was repeated twice more. On each occasion, the seed germination rates were the same, but the white seeds tended to germinate faster.

Why are some cannabis seeds white and some black?
Even cannabis seeds produced from the same branch of a plant can have quite different appearances. Size, as well as shape and colour can vary. Some cannabis strains can produce seeds that have certain appearance characteristics. White Widow seeds, for example, can often be very small and pale. Frisian Dew seeds can have a slightly grey colour.
There have been many theories about how the size, shape and colour of cannabis seeds can affect the plants which they eventually produce. In reality, it’s the cannabis genetics inside the seed case which really determines the results that you can expect. The shell of the seed and the markings on it are purely cosmetic and don’t give any clues to the results you can expect.
In the years before Dutch Passion invented feminised cannabis seeds, people would often try to predict which seeds would produce female plants. Of course, this was impossible. But it didn’t stop people going to great lengths, even measuring the weight of individual seeds in an attempt to derive some knowledge from the seeds physical appearance/size.

Is the colour of seeds a cosmetic difference only?
Some dark cannabis seeds have black lines on them (tiger prints), giving them a distinctive appearance. Other seeds have no significant patterns or markings on them at all. Dark black cannabis seeds can be occasionally seen.
You may also see light vs dark cannabis seeds produced from the same plant. But it’s important to note that cosmetic differences between the seed casing is not a factor which defines how the cannabis seeds grow or germinate.
The genetic material in the soft plant tissue inside the seeds is what really determines the type, size, sex and potency of the cannabis you will eventually grow. These genetics, along with the environment you provide, will control the terpenes, cannabinoids, yield and potency of your eventual cannabis harvest.
Why are some cannabis seeds white and some black? It’s just the way that nature has evolved. Seeds from all kinds of plants and trees show similar variations in their appearance.
What should you look out for in a cannabis seed?
Rather than looking at the appearance of a cannabis seed, you should focus more on the quality of breeding which has gone into the seed. Some growers think that only the largest, tiger-striped cannabis seeds will go on to produce the best plants. Yet some strains will never produce seeds like that.
Time spent researching your cannabis seeds and cannabis seed supplier is time wisely spent. Look for a seed supplier with a good track record in cannabis breeding. Preferably look for a cannabis seed supplier that has been around for a long time with a few cannabis cups and plenty of online reference grows for you to check out before you spend your cash.
Knowing whether you prefer e.g. a Kush, a THC rich vs CBD rich strain, a fruity strain or a Skunk strain is a good place to start. If the array of cannabis seed choices can seem overwhelming, the following article may help you select the best strain for you.
|How to choose the best cannabis strains for you|
Once you have the best cannabis seeds for you, it’s worth ensuring you get maximum germination rates with a good germination method. The preferred Dutch Passion way to germinate cannabis seeds is with moist (but never soaked) cotton pads. If you spot any issue during the growth of your cannabis seeds, we highly recommend to refer to our illustrated guide featuring the key nutrient deficiencies and excesses symptoms and how to cure them.
White cannabis seeds vs dark cannabis seeds
We hope the germination video is a useful illustration of the fact that there is little useful information that can be conveyed by the colour or darkness of a cannabis seed.
Each cannabis strain can produce subtle differences in the size and appearance of their cannabis seeds. You can even expect to see differences between cannabis seeds produced from the same plant. Don’t worry about trying to read too much into cannabis seed appearance. Instead, do your research carefully and select the best cannabis seeds for your particular needs and your specific grow situation. Enjoy growing and good luck!
What Do Cannabis Seeds Look Like?
If you wonder what do cannabis seeds look like, you might not be alone. Many people wonder the same. Cannabis seeds may be as big as 2mm or as small as .5mm but cannabis seeds will always be whitish-brown and have small black spots on them. Although some strains may look different, you cannot actually tell the genetics or sex of the plant by just looking at the cannabis seeds, regardless of the claims people make.
What do cannabis seeds look like can’t define any other characteristics of the strain!
If you are wondering whether the size of the cannabis seeds makes a difference, they actually don’t. You will get the same result from big or small cannabis seeds and they will grow to become massive plants even if they came from smaller-than-usual cannabis seeds. Remember that what cannabis seeds look like will not define the plant that you grow or ultimately the cannabis you smoke.

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.

Hello @ Esox Fables 2022-02-27 02:28:25, You can read some tips here on how to germinate your seeds: https://dutch-passion.blog/the-best-ways-to-germinate-cannabis-seeds/ If your seeds have not sprouted you can reach out to us at [email protected] and we can help you from there! Greetings, Jay Dutch Passion
Hello, I recently purchased some WW auto CBD seeds from you and I’ve been waiting for a week for them to sprout. Prior to use they were kept in my fridge as advised. I’m not sure what I’m doing wrong but they are in a room at 21° and 40% humidity. Is it normal for them to take so long to sprout? Any advice would be much appreciated Thank you, Mick

Hello @Trichy Dicky – 2021-04-03 13:19:57 If a plant hermies it does not mean that all offspring will be hermaphrodite as well. But the plant will definitely be more sensitive to become a hermaphrodite. Many famous varieties have come from a bag seed, so for breeding it can definitely still be used! Greetings, Jay – Dutch Passion
I am finding seeds in cannabis grown indoors and away from males, so a plant decided to hermaphrodite I guess. I THINK all seeds from a hermie will also be hermaphrodite? I wonder! Great company @Dutchpassion
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.
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!
