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.
The Scythians were the ancient race who gave their name to the scythe, thanks to their use of these curve-bladed tools to harvest their crops – including hemp. By 450 BCE, some of their religious rites incorporated hemp seeds, which they threw onto smouldering fires inside small tents where they sat inhaling and bathing in the fumes.
5. Size doesn’t matter!
The oldest cannabis seeds we know of are 2,700 years old and were found in 2007 in a grave in China. As a species, our relationship with cannabis goes back thousands of years that we can trace, and many more that we can only guess at!
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.
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.
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.
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.
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.
Source Your Seeds Well
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.
A quick web search will bring up all kinds of myths about how to tell female cannabis seeds from males. One of the most popular ones comes from a chart showing 5 different seeds that claims that the female seeds have “a perfectly round volcano-like depression at the bottom (from where the seed was attached to the plant).”
The fact that cannabis seeds can vary in appearance has led some growers to think that the size, shape, or color of a seed dictates its quality.
We do not recommend taking the size or shape of a seed into consideration as a sign of its quality. Some strains simply produce smaller seeds than others, and sometimes the same plant can produce seeds of different sizes and shapes. Never discard a seed just because it is smaller or of a different shape than another one.
Let’s take the example of Critical + again, one of our permanent bestsellers that has had a resounding success across the world thanks to its outstanding scent, flavour, effect, and yielding capacity.
This could be compared to a newborn whose physical appearance quickly evolves during their first few days of life in order to adapt to the completely new outside environment.
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.
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.
Cannabis seeds can also show slight changes at morphological level. It’s perfectly normal to find minor differences in the oval shape of seeds from the same batch.
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).
The same thing happens with cannabis seeds: the packaging and the different stages before they’re commercialised can entail lighting and humidity changes, as well as a bit of oxidation, which may slightly affect the colour of the shell but definitely has no impact on the final product. Once again, this is simply a visual effect.
