Good cannabis seeds will be brown, black and / or gray. White or green seeds are immature and unlikely to germinate. Your seed should also have scratches or spots all around.
You have a basic guide to distinguish good from bad seeds. Now if the doubt persists, here are several ways to test the seeds.
Identification of a seed
Unfortunately, there is no way of knowing if a cannabis seed is going to be male or female. And just by looking at it or doing a simple test.
Most of the cannabis seeds offered for sale in seed shops are of high quality. In most cases, they exhibit high germination rates of at least 95% and sometimes even higher . On the other hand, seeds from an unknown source may well be defective and eventually lead to the growth of a weak and disease-prone plant with slow growth rate and low harvest potential.
Another way is to put the seeds on a damp paper towel. Make sure the paper towel is damp, but not too wet… If it gets dry, you can add a few drops of water to the paper towel. Leave the paper towel in a dark place. Remember that the time varies between strains. Some may take just 2 days, while others may take longer… Keep checking them once a day.
While it is best to identify male marijuana plants by their pollen sacs as soon as possible to avoid accidental pollination, there is another way to determine a plant’s sex. If male and female seeds are planted at the same time, the male plants will grow faster and taller than the female plants. Additionally, male plants have longer stems with fewer leaves, making them look spindly compared to female plants.
The largest seeds are the best ones to grow. It is easier to pick the largest ones if there are several to compare side by side. Growers should look for the most symmetrical seed that is round or shaped slightly like a teardrop. Underdeveloped seeds are small and have an asymmetrical shape.
Ask any experienced grower how to produce a hardy marijuana plant and they will say to start with a seed for a good strain. Lighting, soil, nutrients, and water play large roles in the final yield, but starting with a high-quality seed gives growers the best genetics with the highest potential yield possible. Most people find their first seed mixed in with marijuana, but most of these seeds are low quality and may grow to be male plants. The best way to get high-quality seeds is to purchase them from a reputable marijuana seed retailer.
The traditional way to germinate a seed is to bury it one-quarter inch deep in moist soil and watch it closely for a sprout. A freshly germinated seed has a very fragile root that is easily damaged when the seed is transplanted. This method allows the seed to germinate without root interference.
The simplest way for growers to ensure they have high-quality seeds is by sourcing them from a reputable seed bank. These companies specialize in breeding a variety of marijuana strains and producing seeds that, with the right care, grow into viable, high-yielding plants. Growers can choose a variety that meets their requirements for potency and desired effects and be sure they are getting seeds that produce the plant they want.
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.
Poor quality seeds have weak shells that are damaged easily. These seeds will have cracks or splits on them that expose the inside. The best seeds have a smooth exterior with few anomalies.

Unfortunately, there’s not much truth to any of these interpretations. It’s simply impossible to tell just by looking at them what the sex of any cannabis seed is. If it was that easy, feminized marijuana seeds would not be as popular as they are. People could simply buy regular seeds and look at them themselves.
Of all the things that can trip a grower up, sexing marijuana plants may just be the trickiest. Sexing plants is so important because growers are typically after the female plants, that produce the huge THC covered buds. Or the medicinal relief that CBD strains can bring. With such opposite effects of male and female plants, it’s easy to see just how important sexing plants is. But what if growers didn’t have to wait to sex their plants? While it would certainly make life easier, is sexing cannabis seeds possible?
Environment determines sex debate
While growers may not be able to determine the sex of a seed, does the environment have anything to do with it? This is something else that has been hotly contested online.
While environmental factors may not necessarily determine the sex of marijuana plants or cannabis seeds, it is known that certain environments can change the sex of a plant.
Typically, marijuana plants cannot be sexed until they have already begun to grow. Cannabis seeds will look somewhat identical and plants in the vegetative stage will also look identical,. As the plants move into their flowering stage, they will start to show very clear signs as to what sex they are. While it would be much more convenient for growers to be able to determine sex before this point. The sad truth is that it’s just not possible.
So where do all the myths from sexing cannabis seeds come from?
