Yet again, this is a misleading physical attribute that does not guarantee the germination potential or overall characteristics of a seed. A high-quality strain can also be light or dark grey in colour.
If, on the contrary, the seeds seem too big, this may be caused by a lack of macronutrients during the plant’s growth cycle. As any grower with certain experience will know, calcium deficiencies are corrected by adding calcium and magnesium, a combination that helps reestablish the perfect nutritional balance of plants.
Some customers, for instance, contact us to tell us that they have bought Critical + seeds and they believe they look too small. But this is a normal feature of this strain: we’ve seen millions of Critical + seeds and we can confirm that they are naturally smaller than others. It is therefore incorrect to think that this is a sign of poor quality.
So we can openly say that this difference is simply visual. If we take the example of a Moby Dick seed, its dimensions will most likely be bigger than those of Critical +, although you can also find slight variations between seeds from the same strain. Don’t forget that, as with all living beings, cannabis seeds are also biologically different amongst themselves.
So in this case, an increase in size could be a direct indicator of this addition of calcium and magnesium, which is carried out in order to alleviate that macronutrient deficiency during growth. This has no impact on the plant’s potential for germination, growth, flowering, or yield, nor on the development of the organoleptic properties of the buds (aroma, flavour and effect).
Critical + is a clear example that colour, contrary to what many growers believe, is not necessarily a quality indicator: these undeniably high-quality seeds exhibit a very light grey, almost whitish grey, to a medium grey colour.
This article has been conceived to answer all the key questions that we often get asked by clients and growers regarding the physical characteristics of our main product: premium-quality cannabis seeds.
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 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.
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.
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.
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.
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.
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.
