The best temperature to store cannabis seeds is 5 – 7 °C (40 – 45 °F), which is usually the temperature of the door in a domestic refrigerator, handily enough. Cannabis seeds should also be kept perfectly dry to avoid both mould and premature germination. This holds true whether you are keeping cannabis seeds as a souvenir or hemp seeds as food!
Hemp seeds are a common ingredient in bird food, and there is an urban legend of accidental crops caused by someone – usually a grandmother – emptying the bird food bowl at the bottom of the garden and then being arrested six months later for the flourishing plants they were unwittingly growing. In 2014, something like this actually happened, although the story had already been circulating for years.
You can eat cannabis seeds, and they’re good for you! Cannabis sativa L. seeds are a great source of protein, and contain a near-perfect balance of the essential fatty acids (EFA) omega 3, 6 and 9. These are vital to human health and cannot be produced by the body. It is better to eat hemp seeds than cannabis seeds as the former are a lot cheaper! There is no difference in the EFA content of the seeds – just the THC content of the plants they produce. Cannabis seeds do not contain THC (tetrahydrocannabinol) or any other psychoactive substance.
7. Cannabis seeds are collector’s items
Hemp seeds were used by young women to conjure visions of their future husbands. Going out on Midsummer’s Eve (or other significant date, depending on the location), the woman would scatter hempseed on the ground whilst reciting a rhyme that begins “Hempseed I sow, hempseed grow…” nine times. Once this was done, she would look back over her left shoulder and hopefully see her future husband holding a scythe (giving scythes another traditional connection to hemp – see below!). This practice was popular in the 19 th century CE.
Cannabis seeds are usually around the size of a match-head. They can vary by variety from not much larger than a tomato seed to almost as big as a small pea. The size of the seed is no indication of the size (or vitality) of the cannabis plant that will grow from it.
Cannabis seeds are the very essence of our mission, not just part of our company name. We love them, we’re fascinated by them, and we want to share our knowledge with you! Here are ten facts about cannabis seeds that every ‘cannasseur’ should know.
A single cannabis plant can produce hundreds of cannabis seeds – even over a thousand! – depending on its size and the efficiency of pollination. Some hemp strains are bred to enhance seed production for when seeds are the primary crop – for example, for use as a food source.
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.
Another aspect that can be misleading is the fact that a ripe, freshly-harvested cannabis seed has a brighter and darker colour than after it’s been packaged for 1 to 2 months.
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.
Although it is true that ripe cannabis seeds tend to have a dark shell that can go from brown to black, with lines that look like tiger stripes, this cannot be regarded as a quality indicator by itself.
Our 15 years in the business have provided us with a great command as well as a wide perspective of this subject, so it is an honour for us to be able to share our knowledge with all of you in the cannabis community.
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.
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.
Remember, just like animals and other living things, cannabis seeds are biologically different from one another (even if they are technically the same strain) and therefore will exhibit different physical characteristics. Don’t let these natural differences fool you into thinking that a larger, rounder, and darker seed (for example) is of better quality than a lighter, smaller, and more oval-shaped one.
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.
Source Your Seeds Well
We hear this question all the time from clients and beginner growers, and the answer is a resounding no. There is simply no way to tell the sex of a cannabis seed just by looking at it.
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.
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.
This is absolutely not true. As we explained earlier, cannabis seeds naturally look different, and no single physical trait of a seed can tell you whether that seed contains the genetics for a male or female plant. The only way to tell a female cannabis plant from a male is by looking at its flowers when it begins to sex. Don’t be fooled into throwing out perfectly healthy seeds just because a popular internet chart told you so.
