How to Tell if Cannabis Seeds are Good or Bad
Ultimately, you can use the senses of sight, feel, taste and smell to determine whether cannabis seeds are good or bad. You want to make sure you don’t have seeds that have been hastily processed, or damaged for some other reason. Or how about some bluzu those are also great seeds that can do what all other seeds can.
To find out if you have duds (seeds with a low germination rate that will never be ready to plant) or winners, whether you have seeds that will actually sprout or remain permanently dormant, apply these senses to your investigation.
Use a Magnifying Glass to Give the Sight Test
- The best seeds are big and fat with a rounded shape
- The rounder and fatter, the better likelihood that they will sprout.
- The biggest and the chunkiest seeds are the best. They are well fleshed out. The surface should be glossy and hard, with a slight sheen.
- They are dark in colour (usually brown, black or grey). If they are light, white, or pale green, they were harvested way too early and they are probably immature, not good, and unlikely to sprout.
- If they are pale and dusty they are probably old. The older they are, the slower they will germinate.
- The darker the colour, the more likely they are to grow and produce more weed. The dark shell means they came from better quality weed.
- There is a caveat, however. If they are too dark—deep purplish, that means they’ve been dyed and that’s not good.
- Also, beware if you see a white dusty powder on the bud—that is fungus—powdered mildew.
One key as to whether you own healthy cannabis seeds is to look at whether they have slightly lighter stripes. Good seeds are dark with lighter stripes or brown or black spots all the way around. Often, the healthy ones have stripes that resemble lightning, or have a tiger stripe appearance, and a distinctive colour pattern. Take your magnifying glass and look at the stem. If it is furry, that means there is mould from too much moisture—probably because it was bagged too early.There are so many different seeds, bruce banner seed is just one that will do the trick and help you in the long run.
That being said, however, you cannot always judge a seed by its color alone. It can look fantastic, but you need to know what is inside. If you crack a seed open and it is oily and has a musty taste, it is going bad. If it is black inside, that means it’s fermenting and won’t germinate. If you crush it in your hands and you smell salt, it’s unflushed. If the bud is flushed, it means the roots are absorbing salt and nutrients.
Once you have separated the good seeds from the bad via the sight test, touch and feel your seeds as you continue your investigation .
The Touch Test
Lightly squeeze a seed without crushing it. If it crushes easily, it probably will not grow well. As you feel it, there should be no small cracks or holes. If they have small cracks or holes, they probably will not sprout. They should not be crinkled or cracked. If they’re not cracked, you know they are intact. If it holds up under the feel test, it will survive the germinating process.
The Float Test
Good quality seeds will sink – so apply the float test. (Note that you should only do this when ready to germinate). Put them in a cup of warm, distilled water for two hours. If they sink, they’re good. If they float, they are premature, and they probably won’t grow and so are unusable. Healthy seeds are heavy enough to sink.
If you think you have good quality cannabis seeds that have fully matured (that would be seeds with a growth rate of 85%), and are pretty sure you have a great batch of high-quality seeds that are not immature or damaged by the environment, but you’re still saying to yourself, “How do I know for sure I’m going to get a good yield?”, try germinating them.
The last resort test is to just plant it and see if it grows. The ideal temperature is 75 degrees. Good seeds should push up in three to six days. If you don’t want to plant them, you might want to use the paper towel method. Put them in a damp paper towel between two plates, keep the humidity high, and wait two days.
Why your Cannabis Seeds Haven’t Germinated?
If you have been unlucky and some or all of your cannabis seeds haven’t germinated, there is usually an easily identifiable reason. Germination isn’t just about your seed cracking and a taproot appearing, it’s about the transition of a seed into a very small but viable cannabis plant. So let’s start at the beginning.
How long did you soak your seeds in the water?
Did they sink to the bottom of the glass before transferring them to the moist paper towel? Seeds that are still floating are unlikely to have absorbed sufficient water to successfully germinate. If you leave your seeds in water for too long the taproot will not form and the germination process will grind to a halt. Once you have transferred your seeds do the damp paper towel over the next few days.
Did you ever let any parts or all of the paper towels dry out?
At the earliest stages of germination, the smallest of errors can have major consequences. Similarly, the paper towel mustn’t be steeped in water. The taproot grows naturally as it searches for water. If it’s too easy to find it just won’t grow if your water has loads of additives such as copper and chlorine this can poison your plants while handling the seeds with dirty hands can also poison them.
Make sure you either wash your hands with a non-toxic soap wear latex gloves or use tweezers. The next thing to check is the temperature of the seeds. The optimum temperature to keep them good for germination is between 70 and 90 degrees Fahrenheit or 20 to 21 degrees Celsius. If the seeds are too cold they just won’t germinate even. If everything else is perfect.
The owners and members of the Cannabis Clubs claim: “The roots of the plants don’t like light and the same applies to the taproot and subsequent roots that will develop when your seeds germinate. Almost total darkness is ideal for germinating seeds even though.”
It is hopeless for growing seedlings it is interesting to note that it is certain wavelengths of light that affect germination and it is the blue length that tends to corrupt germination, while red wavelength promotes germination. You will also have to take into account when you bought your seeds. While cannabis seeds can remain viable for a large number of years if stored in perfect conditions. They can be ruined in a couple of weeks if not stored correctly.
Finally and unfortunately it is a fact of Mother Nature that not all seeds will germinate. Some will be duds and this is out of our control.
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.
Are These Cannabis Seeds Good?
Growing with bad marijuana seeds is particularly harsh on growers of all levels.
This is mostly because it’s tough to pinpoint when the seed itself is the actual problem. Most growers will blame themselves for a problem that shows up in their grow long before they assume it’s the seeds.
The term ‘bad seeds’ usually refers to any type of seed that has a significantly higher likelihood of causing problems in a grow. I’ll cover the most common reasons for bad seeds in this tutorial!
These cannabis seeds were germinated between two wet pieces of paper towel!
These are pot seeds you might get from a friend, or maybe you have them stashed somewhere and forgot how you got them. In either case, if the shell of the seed looks beat-up, it may not germinate as well or quickly as seeds that were stored in good conditions.
Seeds are a little nugget of genetic material than can hopefully grow into a plant. And like all other genetic material, it doesn’t last forever! Although seeds can be viable for quite years and years after they’re first produced, the chances of them successfully germinating goes down over time (and old seeds also tend to take a lot longer to germinate than fresh ones). The resulting seedlings are also more likely to be slow growing. But sometimes they sprout like they were born yesterday!
Check out the picture below. We sprouted all the plants at the same time. The tub on the right has seeds that were planted within a week of receiving them in the mail. The tub on the left has a very popular strain with award-winning genetics… but the seeds were more than 6 years old from when we first bought them. Even though they were all put into the tank at the same time and the new seeds grew like crazy, the seeds on the left got outpaced by algae – only one sprouted and though its roots keep growing and growing the actual never got any bigger than two round leaves even after a month!
Pale or Flimsy Seeds
When I first started growing I was told that good cannabis seeds needed to be very hard with dark tiger striping. If you could crush it between your fingers, it was a bad seed, or so I was told. This has not been my experience at all!
Did you know that the “stripes” on cannabis seeds are actually part of a protective coating? The “pale” seeds in this photo are actually just regular seeds with the coating rubbed off!
Over the years, some of my very best plants came from flimsy, light brown seeds that very likely would have been easy to crush between my fingers.
So I’m a big believer in the fact that if you put the seed in the ground and a fast-growing healthy seedling comes out of it, it was a viable seed! Don’t toss a seed you are really interested in just because it’s a little pale; give it a chance (I’m talking more about tan seeds, it’s very unlikely a yellow seed will sprout)!
Note: Although the hardiness of the seed was likely important in the wild, cannabis growers have been breeding plants for generations to make good buds, not seeds! We growers strive to provide an ideal germination environment that lets almost any seed germinate successfully. As a result, we haven’t been breeding for seed hardness. Just like a teacup poodle hasn’t been bred to be strong, cannabis seeds haven’t been bred to be strong. They have other qualities we love
Bag seeds you randomly find in your buds aren’t supposed to be there, so that means that the genetics are a toss-up. Even if the seeds started with good parents, there’s no telling how high or low the quality will be. Unfortunately, the only way to find out is to grow it… Some growers win the genetic lottery, but many others lose out.
If you talk to breeders, you’ll learn that when you breed two “star” strains together you don’t always get what you’d expect. It seems like every one of the seedlings (or at least most of them) should be capture the best qualities of both their parents.
However, that’s not how genetics works most of the time. Without intensive breeding and backcrossing, when you mix two random plants you often end up with only a fraction of the seedlings capturing the best of both parents.
Bag seeds are a wildcard! You never know what you’ll end up with!
So depending on how the seed was originally made, bagseed often has a lot of variety. Even if the buds you got were an incredible quality, it doesn’t necessarily mean that the seeds will produce buds like that. If you’ve ever gotten involved with breeding or growing other types of specialized plants like roses, hops or even apples, you’ll know that seeds rarely breed “true” to the parents, and cannabis isn’t any different.
That being said, sometimes bagseed is all you have, and lots of growers get lucky!
Hermaphrodite or Male Plants
If a cannabis seed was produced with a male doing the pollinating, it means that about half of the resulting seeds will end up being male (which you don’t want, because only female flowers turn into bud). In that case, you want to determine the gender of your young plants as soon as you can so you can toss all the male ones before they start making pollen sacs.
If growing with seeds that were produced without a male plant around, the seeds sometimes end up being hermaphrodites, which means they grow both male pollen sacs and female flowers (again, something you don’t want).
One of the best ways to ensure all your plants end up being female is to start with feminized cannabis seeds from a trustworthy breeder.
Sometimes It’s Random!
Even if you’re starting with the best, most fresh seed stock, occasionally you’ll get an individual seed or plant that just doesn’t grow as well or quickly as the others, or maybe you’ll get a super awesome seedlings that just starts kicking butts and taking names from its first moment.
Natural variation is totally normal! It’s always a good idea to sprout at least a few more seeds than you need in case you happen to run into a runt, or some other expected problem! If all your plants are healthy and growing fast except one, you can blame the seed!
