How to tell if it’s a good weed seed

10 Markers of a Quality Marijuana Seed

If you’re looking to start growing your own marijuana, the first place to start is with the seed. What should you look for? How can you tell a good cannabis seed from a dud? Chris Bond tells us.

So, you’ve decided to grow your own marijuana from seed. How do you know if those little, round nuggets in your hand will grow up lush and produce beautiful, productive buds? How do you know if they are duds? While ultimately the genetics will determine the destiny of those little weed seeds, and proper care will help them to realize their full potential, there are some markers you can assess to see if what you have is quality seed, indeed.

What to Look for in a Cannabis Seed

#1 Color

While all cannabis seed is not identical in color, there are some consistencies. Healthy, viable seed will be light to dark brown in color. Seed that is light green or even whitish in color is underdeveloped and should be tossed out. Healthy seed will also have a burled or turtle shell-like pattern on its seed coat.

#2 Sheen

A quality cannabis seed will have a waxy, protective coating. Seeds that appear dull are probably not as viable and should be avoided if given a choice.

#3 Shape

Quality cannabis seed will look like a plump teardrop. Flat or misshapen seeds will not likely produce quality plants.

#4 Texture

Quality seed will be firm. Cannabis seed should have a strong seed coat protecting the pre-emerged life inside. Any seed that is tender, pliable or squishy should not be planted; poor results will follow if attempted.

#5 Size

Size is relative, but if you are able to compare several seeds at once, the higher quality seeds are larger. When it comes to seeds, less is more. The fewer seeds that comprise any given amount, an ounce or a gram for example, is generally an indicator of higher quality seeds. The biggest seeds within a species generally have more energy stored within them and have a greater potential to mature into a productive plant. Note that indica strains tend to produce larger seeds than sativa strains so make sure the comparison is made among like seeds.

#6 Weight

Weight often goes hand-in-hand with size, but heavier seeds are generally of higher quality than lighter ones. The older a seed gets, the more potential loss of moisture and nutrients, reducing its overall weight. Damaged seed, which has been cracked can potentially lose those same necessary qualities.

#7 Float test

Quality seeds will sink in water. In glass or vessel, place room temperature water deep enough to full cover the volume of seeds to be tested. Place your seed or seeds in the water. After a couple of hours, anything still floating, should not be considered a quality seed. Soaking seeds will allow moisture to cross over the protective membrane and signal the seed that it is time to grow. As such this test should not be performed if the intent is to store the seeds after testing as it may render otherwise quality seed unviable if not meant to be immediately germinated afterwards.

#8 Storage

You may not have access to see or have verified information on the storage conditions of seeds, but if you can find this out, it is critical to maintaining quality seeds. While cannabis seeds can be viable for over 10 years in some instances, the best seed in terms of productivity is not more than 12 to 18 months old. It should have been stored in dark, cool and dry conditions to prevent mold or the onset of any fungal issues. Storing in a freezer can prolong seeds as well, essentially suspending time.

#9 Age at harvest

This is another aspect you, the buyer may not be privy to. Quality seed is harvest when fully mature. If seed was collected before the plant was able to load as much stored energy into it as possible, then that seed will be starting out life in a deficit. Color, as referenced above can be an indicator of whether or not a seed was harvested at the appropriate time.

#10 Cost

You get what you pay for and a cannabis seed is not exempt from this maxim. Quality seeds are not cheap (at least when compared to other agricultural seeds). This isn’t to say that inferior seeds can’t be overpriced, but if you find cannabis seeds proclaiming excellent genetics for sale at a price that seems too good to be true, caveat emptor.

This is not meant to be a definitive list, as new varieties of cannabis emerge on the scene all the time that may have “normal” traits that would otherwise be viewed as deficiencies in other strains. As always, do your homework, ask other growers who know and buy your seeds from a reputable source.

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:

Dark Color

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.

Young Seeds

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 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.
