The use of high-quality seeds is one of the key requirements for growing healthy cannabis plants. It is true that the final yield depends on numerous factors including adequate watering, availability of nutrients, and good light quality. However, it all starts with superior genetics. In order to ensure that you receive the exact genetics you are looking for, it is important for you to source high-quality cannabis seeds. This will not only provide you the cannabinoid and terpene profiles you desire but will also help get rid of dud seeds.
According to information from i49 , an authentic cannabis seed bank, there are several factors to be examined and evaluated while purchasing seeds. There are certain signs that clearly indicate whether the seed is worth all the effort and hard work or not. Mentioned below are some of these factors.
Feel and Appearance : One of the easiest ways to evaluate the traits and quality of cannabis seed is to get accustomed to their appearance. In general, the outer shells of genetically superior and healthier seeds tend to have darker shades. One of the most obvious signs of some good seeds is grey and black shades with the occasional display of a tiger stripe. The appearance of healthy seeds will also resemble a wax coating on the shell surface, particularly when exposed to bright light.
In addition to a darker shade, better-quality seeds are quite firm and do not bend or break when squeezed between the thumb and index finger. On the other hand, old or poor quality seeds crack and crumble easily under pressure. Please remember that these seeds are nothing but pods of plant genetics. Over a period of time, they get aged and are no longer fit for use. Therefore, do not waste your time on seeds that are past their prime.
You should also avoid using seeds that are immature and young because they are unlikely to germinate. Even if they do, it will take much longer. These seeds can be identified by their green and white appearance.
Avoid Seeds from a Bag : You may consider yourself lucky to find some seeds in your cannabis bag. However, these seeds are not good for a number of reasons. Firstly, this is an indication that the grower has messed up and allowed an invading male to pollinate the female plants. Once pollinated, the female plants shift their focus entirely towards producing seeds and stop producing THC-containing resin. Moreover, the seeds also add to the bag’s overall weight. This certainly means less weed for your money.
Germinate the Seed : One of the best ways to evaluate the genetic potential of cannabis seeds is to simply put them in the soil. You will see the result within a very short time. This option is ideally suited for home growers with adequate time and space to spare. However, this may not be a suitable alternative for commercial growers.
Proper Sourcing : Without any doubt, the most trustworthy source to find great seeds is a reputable seed bank . These organizations have excellent breeding skills and are known to deliver exactly what they advertise to their customers. Many of these seed banks have an excellent reputation in the market.
Float Test : If you are not satisfied after analyzing the appearance and toughness of the seeds and still have doubts about seed quality, carry out the float test. Fill up a glass jar or drinking glass with water and place the seeds on the surface. Seeds that remain floating on the water surface are likely to be of poor quality. On the other hand, healthier seeds will sink to the bottom.
Be patient while conducting the float test because the result may not be seen immediately. Some high-quality seeds need time to absorb enough water and sink to the bottom of the container. Therefore, before confirming the results, you must wait for 1-2 hours.
How to Spot Bad Cannabis Seeds [Comprehensive Guide]
You may not realize it, but the quality of your cannabis crop is, in part, determined before you have even begun. Seed quality is an enormous part of growing, so it’s vital to source marijuana seeds from a reputable company.
Sometimes, you can end up with ‘bad’ cannabis seeds that will cause problems later down the line. In some cases, these seeds just won’t germinate. Although this won’t ruin your entire crop, it is a waste of time and money, which can be frustrating.
Today, we will help you work out whether your cannabis seeds are good or bad. Hopefully, this guide will help you to determine which seeds are worthy of your time and which ones are duds.
What Makes a Cannabis Seed ‘Bad’?
A ‘bad seed’ is any cannabis seed that will cause problems. In some instances, this means a dud seed that never sprouts, wasting your valuable time and a few resources. While dud seeds aren’t damaging, they are irritating.
Another type of bad seeds is male cannabis plants. There’s a 50/50 chance with regular seeds as to whether any given seed is male or female. The problem is that male plants will pollinate the females once they reach maturity, destroying the valuable THC content of female plants.
Having male cannabis plants in your garden is basically a recipe for disaster, so you want to avoid it at all costs. By the way, here’s how to figure out if your plants are male or female.
One way around this is to purchase feminized marijuana seeds. In theory, all seeds in a feminized bunch will be female – unless you buy from a disreputable grower. Unfortunately, there’s no way to tell whether a plant is male or female simply based on the seeds.
This guide will only cover how to tell the difference between a potent seed and a dud seed.

How to Test Cannabis Seeds
There are several easy methods for testing cannabis seeds. Most of them can be performed before germination, saving you some time and resources. Let’s find out how to check your seeds.
Method #1: The Sight Test
Cannabis seeds are surprisingly beautiful. They have a mottled brown appearance with patches of light and dark, and sometimes gorgeous tiger stripes. The seeds are also quite shiny if you view them close enough.
Sometimes, you can tell if a seed is good or bad just by looking at it. Here’s how to spot a healthy seed:
- Coloration: A dark coloration with black or gray patches is a sign of a healthy seed. Conversely, white or green seeds are unlikely to germinate because they are not mature. Pale seeds are also more likely to be old and ineffective.
- Waxy coating: Healthy seeds have a waxy, shiny coating. If it doesn’t, then the seed is likely a dud
- Cracks: Cannabis seeds should not be cracked. If your seed has cracks in it, it’s probably best to discard it.
- Shape: The rounder and fatter the seed, the more likely it is to sprout into a healthy plant. Some growers are concerned about large seeds with thick shells but don’t worry. The shell will break down with water.
- Mildew: Grab a magnifying glass and view the seeds close up. A white, dusty powder is a sign of powdered mildew, which means the seeds have a fungus and should not be planted.
In some instances, you can crack the seed open and see inside if you can’t tell anything from the outer shell. An oily inside with a musty smell means that the seed has gone bad. Similarly, black inside the seed means that it’s fermenting. Again, it won’t germinate in this instance.
Method #2: The Touch Test
The feel of cannabis seeds is another good indicator. Hold the seed between your thumb and forefinger and give it a light squeeze. Don’t apply too much pressure – just enough to test its integrity.
If the seed cracks under slight pressure, then it’s unusable. It’s likely to be past its sell-by date.
Strong seeds, however, have a better chance of germinating and growing into a healthy plant.
Method #3: The Water Test
Are you still unsure about your cannabis seeds? You can always do a floating test to see if they’re healthy. By the way, this method works for numerous plant seeds and not just cannabis.
Disclaimer: Don’t perform this test unless you’re ready to germinate the plants right away. The water could damage the seed and ruin a perfectly healthy plant if you dry it out afterward.
For this test, you will need a cup, glass, or bowl of warm water. It should be quite warm, but not hot. It also works best with spring water or distilled water.
Add your seeds to the water, and then wait for 1-2 hours. Those that float on the surface are bad seeds that are unlikely to grow, whereas the seeds that sink are probably healthy.
This method is a great way to check your seeds because it’s low effort. You can also test multiple seeds at once, and it’s really cheap and easy to do.
After you’ve done this test, you need to germinate the healthy seeds. At this point, they will have absorbed water, which can damage the seed if you don’t germinate it at this point. Incidentally, germination is the final test for your seeds.
Method #4: The Germination Test
If all else fails, it’s time to germinate. You might have no idea whether your seeds are healthy but attempting to grow them is an easy final test that will separate good seeds from duds.
There are multiple ways to germinate, including planting the seed directly in soil and seeing if it sprouts. This is a pretty ‘old-school’ method, but sometimes, it works.
More commonly, growers use the paper towel method. Dampen a paper towel, ensuring it isn’t soaking wet. Place this on a kitchen plate and put the seeds on top, then put another plate upside-down on top. A moist, dark, warm environment allows the seeds to sprout. Check on the seeds once a day; after germinating, you should see a white taproot emerge.
At this point, you can transplant the seed into its pot. Use a pair of tweezers and handle each seed carefully, being careful not to touch the taproot. The taproot is fragile and may break if you’re not delicate; furthermore, touching it with your hands may contaminate it.
After germination, you’re good to go. Remember to check back as the plants mature to make sure you haven’t got any male cannabis plants.
Waste not, want not!…
How to Buy Good Cannabis Seeds Every Time
It’s recommended to buy feminized cannabis seeds to eliminate the possibility of males ruining your crop. Even so, some subpar retailers will advertise feminized seeds, only to sell regular cannabis seeds.
It’s vital to buy from a reputable seller that you trust. If this is your first time, read reviews on the seed banks to find out what other customers thought. If lots of buyers were disappointed by low-quality seeds, avoid that company!
Unfortunately, you might still get some bad seeds sometimes. Plants are living beings and can be a bit unpredictable – even the seller might not be aware that some of their seeds are duds. With any luck, the majority of seeds you buy will be healthy and good to go.
The sign of a bad seller is that their seeds are consistently old, dead, and covered in powdery mildew. That said, don’t be too harsh on a seed bank if a couple of their seeds don’t work from time to time when they’re generally reliable.
Final Thoughts on Good and Bad Cannabis Seeds
Telling good and bad cannabis seeds apart is not an exact science. Sadly, you don’t know what’s inside the seed beyond its appearance, so you won’t know what the plant is truly like until you start growing it.
Cultivating marijuana is a bit of a learning curve, so don’t worry if you mess up your crop from time to time. It will only get easier with time.
Hopefully, you can now tell apart some seeds, at least, giving you more opportunities to create a successful grow.
