Bad cannabis seeds can ruin an entire grow. Here's how to spot them early and save yourself a whole lot of time and effort. Have you ever wondered why some seeds SINK when placed in water, while others FLOAT? The answer has a lot to do with the seed coat and… Just curious if it makes a difference as far as if the seed is good or not if it sinks or floats?

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.

The complete guide…

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.

Weed Seeds Float Or Sink

Are Marijuana Seeds Good When They Float in Water?

Table of content

As anyone who has ever tried to grow marijuana knows, getting the seeds to germinate can be a tricky process. There are a lot of factors that come into play, and if even one is off, it can mean the difference between a bountiful harvest and a disappointing one. So when you’re trying to germinate your seeds, you’ll take any edge you can get. Which is why some people swear by the float test.

Should my marijuana seeds float?

Marijuana seeds are known to float. However, some people believe that marijuana seeds sink in water. There is no right or wrong answer to this question, as it depends on the specific water conditions and the type of marijuana seed.

Are seeds viable if they float?

Marijuana seeds float in water, but are they viable? The short answer is that it depends on the strain of marijuana.

Some strains of marijuana are more prone to floating and others are more prone to sinking. However, most strains of marijuana can be viable if they sink in water.

How do you tell if a seed is good or bad?

Marijuana seeds can sometimes float on water and look like small, white pebbles. If the seed is rotten or has fungus growing on it, it will sink to the bottom quickly. Healthy marijuana seeds will float on top of water and take a while to sink.

Why do some seeds float on water?

Have you ever wondered why some seeds sink when placed in water, while others float? The answer has a lot to do with the embryo and the seed coat. The embryo is responsible for the seed’s buoyancy. The embryo consists of a layer of cells that accounts for 65% of the seed weight. This layer of cells contains air pockets, which make the embryo more resistant to sinking and helps it stay afloat on water. Additionally, this layer of cells contains oil globules that give the seed its characteristic greasy texture. The seed coat is made up of tough layers that protect the embryo and absorb water. These layers also contain air pockets and oil globules. When water enters these pockets, it creates a force that pushes up ward against the surrounding layer of oil globules, making the seed float on water.

How long do you leave seeds in water?

One of the key questions when it comes to growing marijuana is whether or not you should leave your seeds in water. Many people believe that if the seeds are left in water they will germinate and grow. However, there is no definitive answer as to how long you should leave the seeds in water before removing them. Many growers recommend leaving the seeds in water for anywhere from 12- 24 hours before rinsing them off and planting them. The length of time that you leave the seeds in water will largely depend on a few factors such as temperature, humidity, and light availability.

What happens when seeds are soaked in water?

When seeds are soaked in water, they will start to sink. This is because the water will fill up the spaces between the seeds and cause them to sink. The water will also cause the seeds to swell, which will make them heavier and cause them to sink even more.

Can seeds germinate in water only?

Some people believe that marijuana seeds should not be submerged in water because they may sink to the bottom. True or false, does this theory work?

The answer is both yes and no. The truth is that some of the seeds will sink to the bottom while others will float, but it doesn’t matter because they all end up growing marijuana plants either way. What matters more is how well the seed was soaked in water and if it has any mold or fungus on it. If there are any contaminants on the seed, then exposure to water can cause problems such as mold growth or even cell death.

It is generally believed that marijuana seeds are good when they float in water. However, there is no scientific evidence to support this claim. While some people believe that sinking seeds are more viable, there is no guarantee that this is the case. It is also important to note that bad seeds can float as well, so it is not a foolproof method of determining seed quality. If you want to soak your seeds in water, it is recommended that you do so for 12-24 hours before planting them. This will give them time to germinate and start growing into healthy plants.

Does it mean amything when seeds float vs sink?

I don’t think the good egg/ bad egg rule applies here. Never tried germinating my seeds in a cup of water.

Soak them for 24 hrs and plant them sink or float or regardless how they look.

Float or sink they may still grow.
