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.
How to Tell if a Cannabis Seed is Good
Got a cannabis seed, but you’re not sure if it’s any good? No worries. By the end of this article you’ll know everything you need to get started.
The legality of growing cannabis varies depending on where you live in the world. Know your laws.
What to Look for in a Healthy Cannabis Seed:
You can tell a lot about a seed’s health just by looking at it. Here are a few different things you should look for when deciding if a cannabis seed is good or not.
- Darkened Color – Good cannabis seeds will be brown, black, and/or gray. White or green seeds are immature and unlikely to sprout. Your seed should also have stripes or spots all the way around.
- Waxy Coating – A healthy seed will have a thin waxy coating around it. This coating should appear to have a slight sheen to it.
- Hard Shell – You should be able to lightly squeeze a seed without it crushing. If a seed crushes easily between your fingers then the seed is likely dead or weak and will not grow well.
- No Cracks – Inspect the entire seed to make sure there aren’t any small crack or holes. This will most likely cause the seed not to sprout.
Ways To Test Cannabis Seeds
Now that I’ve gone over a basic guide for what to look for I’ll give you a couple of ways that you can test your seeds.
Test Method #1: Floating Seeds in Water
This is a great test that works for many different seeds – not just cannabis. Take your seeds and drop them in a cup full of warm (not too hot) water then wait a couple of hours. If they sink then they’re probably good to go. If they won’t sink then they are probably dead and won’t grow.
Note: Only do this if you’re ready to germinate your plants. Otherwise, it could harm your seed. I cover germination in a later section.
Test Method #2: Just Go Ahead and Try to Germinate the Seed
I know this seems obvious, but it really is the best information I really could give. If you really want to know if a cannabis seed is able to germinate then go ahead and try germinating it – what do you really have to lose? Not quite sure how to germinate a seed? No worries. Here’s a quick guide:
How to Germinate a Cannabis Seed
Germinating a seed simply means getting the plant to sprout from the seed. It’s the first step in your cannabis seed’s journey to a full grown plant. There are several ways to go about this.
One way is to simply plant it in your soil and see if a plant pops up. It’s old school, but no one can deny its simplicity. Plant the seed about 1/4″ deep and wait.
Another way is to put the seeds on a damp paper towel. Make sure the paper towel is damp, but not soaking wet. If it dries out you can add a few drops of water to the paper towel. Leave the paper towel in a dark place. The amount of time is going to vary among strains. Some may take only 2 days while others could take longer. Continue to check them once a day.
How to Tell if a Cannabis Seed is Male or Female
Unfortunately, there is no way to know if a cannabis seed is going to be male or female simply by looking at it or doing a simple test. This is a bummer since most people don’t want male cannabis plants in their garden.
If you want feminized seeds then you’ll have to buy them from a reputable seed bank. Make sure they say feminized – if they don’t say it then they probably aren’t.
If all you’ve got is a bag seed then the only way to find out if it’s going to be male or female is to grow it.
Can My Cannabis Seed Go Bad / Expire?
The short answer is yes, but if you store your seeds properly they can stay viable for years and years. Moisture, UV degradation, and extreme temperatures could all affect the quality of your seeds.
If you plan to store your seeds for a long period of time make sure to keep them in an airtight container in a dark area. Ideally, seeds should be stored in a climate controlled area (like inside your house instead of in a shed or garage. One study showed laboratory-sealed cannabis seeds 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 soil. If you’re using bag seeds then you never really know what you’re getting anyways. If you’ve bought your seeds from a legitimate seed bank then you shouldn’t have to worry about it.
How to tell if a seed is dead? Here are some tricks
Sometimes hemp seeds do not germinate because they are lifeless. Here’s how to spot a dead hemp seed and avoid wasting time
In previous articles, we have repeatedly stressed how the quality of cannabis seeds can make all the difference in achieving a healthy and productive plantation.
Poor quality seeds can lead to weak and unprofitable plants or even to no germination at all.

This article will learn how to recognise quality hemp seeds (such as BSF seeds) and tell if a seed is dead and therefore totally useless.
Dead or bad hemp seed: here’s why quality is essential
In the field of hemp growing, some choose to buy ready-made seedlings, and those prefer to plant the marijuana seeds themselves so that they can monitor the growth of the plantation from the very beginning.
Of course, in order not to waste time, it is essential to make sure that you are dealing with quality seeds of the right genetics (such as auto-flowering seeds, feminised seeds, etc., which you can find for sale at SensorySeeds), but above all, they must be alive!
Yes, you got that right!
If the seeds are too old or have been stored incorrectly, they may have lost their ability to germinate, and so, even if you put your mind to it, the seedlings won’t grow.
In the next section, we will clarify the main signs that the seeds you have in your hands may be lifeless.
Dead seeds: how to recognise them?
Many novice cannabis growers are tempted to buy low-quality marijuana seeds because they are sold cheaply.
Up to this point, it all seems quite normal. However, in such cases, the problem is that the seedlings often do not grow, and it isn’t easy to understand the cause.
Many people wonder what they might have done wrong and try to figure out what to do if the seeds do not germinate.
Of course, sometimes you make mistakes, but you have to check whether the seeds you have bought are still alive in other cases.
Knowing how to distinguish high-quality seeds from bad ones is very important to avoid wasting time and money.
Let’s start with the appearance.
Good quality seeds usually have a kind of waxy layer that shines when exposed to light. As a result, their colour can vary from brown to grey or black, with some speckling.
If you are dealing with white or light green cannabis seeds, they are immature and unable to germinate.
Seeds that appear ‘dried out’, have cracks or dents are of poor quality.
You can also tell by touch whether the seeds are good or not.
If you hold a hemp seed between your index finger and thumb and apply pressure, some seeds crumble, while others do not at all. The quality ones and the ones most likely to be alive are, of course, the latter.
A test is considered almost foolproof to see if hemp seeds can germinate: water immersion.
If by putting them in a glass with warm water they float, then it means they are dead or rotten; whereas if they go down, they are of good quality.
Of course, all these tricks apply to seeds of all genetics and types.
If we have intrigued you, you too can try floating feminised seeds, fast seeds or auto-flowering seeds from your collection (but remember that growing cannabis is not allowed in the UK).
Concerning the flotation test, however, we would also like to point out that it should only be carried out during the hours before sowing and that the seeds must be removed from the water within 24 hours. Otherwise, they will be irreparably damaged.
Live seeds which do not germinate: what is the cause?
If also thanks to the advice given above, we know that our seeds are alive but still do not germinate, there is probably another cause.
Let’s see what the main ones might be.
- Soil which is too cold
- Sometimes it is the temperature of the soil that is too cold that prevents marijuana seeds from germinating. If you keep the soil warm enough, you will see faster germination.
- Incorrect choice of substrate
- It is usually recommended to use a relatively friable and light substrate when sowing cannabis. If the seedlings do not germinate, the root growth may be prevented by too loamy and difficult to penetrate.
- Sowing too deep
- Cannabis seeds, being relatively small, should be planted close to the surface of the soil. Otherwise, the sprouts will not be able to emerge.
- Insufficient irrigation
- Sometimes cannabis seeds fail to germinate because they are not watered enough.
- It is essential to keep the soil well moist, as this is the only way for the seeds to swell and germinate.
As we have seen, you can use a few tricks to find out if your cannabis seeds are dead or not.
Unfortunately, even if the seeds appear to be alive and of good quality, they may have genetic defects. That is why the best choice is always to buy quality fast flowering seeds (such as BSF seeds) at the outset.
