How to Tell If a Weed Seed is Good
Cannabis seeds are where cannabis life begins. However, not all seeds are good, and so you have to sort through the good ones and the bad ones so that you can grow some good cannabis buds. But how do you tell when cannabis seeds are bad or good? Let’s explore these two different options.
Why Should You Start With Healthy Cannabis Seeds?
If you want to grow incredible cannabis plants, you should begin with the appropriate fundamentals. You have to sow the highest quality cannabis seeds to essentially encourage your seeds to grow vigorous and dynamic plants.
You have to know how to differentiate between the seeds that are of the lowest and highest quality. This will save you tons of time and money.
The benefits of starting with a high-quality cannabis seed include:
- Improved germination rates
- Higher-quality genetics
- Better yields
- Better aroma and flavor
- Better overall buds
For each small cannabis seed you plan to use, you have to consider the various aspects and features including its size, shape, sex, color, origin, strain, and gender. Here, we have provided you with some of the details that will help you distinguish the ultimate cannabis seeds from the ones that are useless.
How to Tell if a Weed Seed is Good
How do you figure out which seed is good? Well, at first glance, it has to look healthy. To detect good cannabis seeds, you have to also know what to expect in shape, color, and size, even though these features don’t always guarantee successful sprouting.
Due to the wide variety of strain genetics available, healthy cannabis seeds can vary in appearance.
Here are a few signs to look for when choosing high-quality cannabis seeds:
Healthy seeds will usually be grey, brown, or black with darker spots and lines that do not usually have an expected pattern. Good seeds can have any uniform color across their exterior or display tiger stripe or turtle shell patterns with varying dark hues.
The coat of the seed may also be waxy, reflecting light when it is exposed. Keep in mind, variations in color can depend on be strain genetics, growing environment, and storage practices. For instance, seeds can develop a darker shade when they have been stored or several months.
Large Size and Tear-Drop Shape
It can be hard to determine if a cannabis seed is good or bad depending on its size and shape alone. High quality cannabis seeds can be small or large. If you are small seed displays other features of a good seed, then it is a good candidate for germination.
Generally, healthy cannabis seeds will appear very large once developed. A large seed shape can be due to its unique genetics or high concentrations of magnesium and calcium. However, there is still no guarantee ofsprouting seeds, even if you have a large seed.
In terms of shape, good cannabis seeds tend to have a tear-drop shape with a round end on one side and a tapered end on the other. Generally, seeds that do not have this shape have a lower risk of viability.
Age is a helpful indicator of the quality of the seed. However, it can be hard to tell the age of a seed if you didn’t grow it yourself. Generally, seeds that are under a year old are the best for a successful harvest. Younger seeds have a faster germination rate and are less likely to go bad if stored for a short period of time.
Cannabis growers can store their seeds for several years in the refrigerator to extend their longevity. However, planting the seeds when they are relatively young will provide you with overall better results.
If you have no idea how old your seeds are, here’s a good way to estimate their age:
Gently squeeze the seed between your thumb and index finger. The younger and healthier the seed is, the firmer it will feel.
The Bad Cannabis Seed
How do you figure out which seed is bad? Here are a few ways you can tell if your cannabis seed has gone bad.

Cannabis Seed Identification Guide: distinguishing viable seeds from non-viable seeds before planting
Strong, high quality cannabis seeds will ensure a high quality cannabis plant. So, if and how is it possible to identify whether cannabis seeds are good or not? And how long do these seeds retain their vitality? Answers on seed identification:
Identification of a seed
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.
You can tell a lot about the health of a seed by looking at it. Here are a few different things you should look for when deciding whether a cannabis seed is good or not.
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.
A healthy seed will have a thin waxy coating around it. This coating seems to have a slight shine.
You should be able to lightly squeeze a seed without crushing. If a seed crushes easily between your fingers, the seed is probably dead or weak and will not grow well.
Inspect the entire seed to make sure there are no small cracks or holes. This will likely cause the seeds to not sprout.
Means of testing cannabis seeds
You have a basic guide to distinguish good from bad seeds. Now if the doubt persists, here are several ways to test the seeds.
Test method No.1: seeds floating in water
It’s a great test that works for many different seeds – and not just cannabis. Take your seeds and drop them in a cup full of hot water (not too hot) then wait a few hours. If they sink, they are probably good for a crop. If they don’t leak, they’re probably dead and won’t grow.
Note: Do this only if you are ready to germinate your plants. Otherwise, it could hurt your seed.
2 test method: just before and try to sprout the seed
I know it sounds obvious, but it really is the best information .
If you really want to know if a cannabis seed is capable of germinating, put it in the ground .
How to sprout a cannabis seed
This is the first step in the journey from your cannabis nursery to a whole plant. There are several ways to do this. One of the ways is to just plant it in your soil and see if a plant appears. It’s old school, but no one can deny its simplicity. Plant the seed about 1/4 “(inch) deep and wait.
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.
Male or female ?
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.
If you want feminized seeds, you will need to buy them from a reputable seed bank. Make sure they say they are “feminized” – if they don’t, the seeds probably won’t, or rather randomly. These are the so-called “regular” seeds
If all you get is a bag seed, the only way to know if it’s going to be male or female is to develop it.
The seeds have an expiration date. But if you store your seeds properly, they can remain viable for years and years. Moisture, UV degradation and extreme temperatures could affect the quality of your seeds.
If you plan to store your seeds for a long time, be sure to keep them in an airtight container in a dark area. Ideally, seeds should be stored in an air-conditioned area (such as inside your home rather than in a shed or garage). A survey shows that cannabis seeds sealed in the laboratory were still viable after 19 years.
It’s nice to know what to look for, but in the end the best test is just to put it in the ground.
If you are using seed bags you never really know what you will get anyway. If you bought your seeds from a seed bank, you shouldn’t worry about it.
