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.

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!
