How To Tell If Cannabis Seeds Are Bad

The quality of your seeds when you plant them can impact the entire lifespan of a plant and the end product that you get to harvest. Let's explore the two options available to growers to test their seeds for quality. Learn how to tell if a weed seed is good.

How to tell if your cannabis seeds are bad

When you’re just learning how to grow, there are so many things that can get in the way of you achieving success, and one of them that is most common is a bad batch of cannabis seeds. Once you’ve got a grow room well established, your lights set up and ready, soil PH kits handy, and fertilizers on tap, all that’s left to do is to get some pot seeds germinated, but if you’ve never done it before, it can be hard to tell if the troubles that you might experience are attributed to the seeds that you’ve used or the methods that you’re trying to get them going.

We all have that one friend who claims to have grown a spectacular plant with some scary looking or ancient pot seeds, but that doesn’t mean that everyone will have that same kind of success. In fact, the quality of your seeds when you plant them can impact the entire lifespan of a plant and the end product that you get to harvest from it, so it’s best to be selective as you go through this process. Unfortunately, there is no way to know for certain if your weed seeds have expired, but these are a few of the most important features to look for when doing an assessment of potential.

1. Color and designs

All cannabis seeds, no matter the strain, can vary significantly in color, shade, and design patterns. Some are duller than others, and a few have such incredible prints on the casing that they resemble a professional piece of artwork, with lines and shapes of all different types everywhere. However, if your pot seeds are a bright white color or a deep hue of black or gray, then that is a pretty good indication that they might not be very good, to begin with, as these characteristics tend to appear from age, or water damage, both of which can render cannabis seeds completely useless in no time.

2. Damage

At first glance, it might be hard to see if your weed seeds have been damaged in any way, as the variety of darker colors can help to mask what could be major problems, on a tiny shell. However, if you get a magnifying glass, or pull out a seed and hold it up in the sunlight, you can usually see if there are any cracks, dents, or scratches on the outer casing, and the presence of any of these things could indicate a problem. Another way to check is by using your sense of touch by running your fingertips over the sides and edges, to feel for any breaks in your cannabis seeds

3. Age

Do you have any idea how old the weed seeds you’re using might be? As much as these gifts from nature can hold up quite well for a while in storage, certain influences can dramatically shorten their potential lifespan. Too much heat or moisture can be devastating and lead to mold or baking of the seed, leaving it completely useless in no time, and abrasive handling can leave behind hairline fractures that expose the middle of the seed to air, which also hastens the aging process. Even if everything is done right, it’s best to start out with pot seeds that are less than two years old for the highest rates of success, or they could be bad by the time you got to use them.

4. Issues with germination

Have you been trying every method that you can find online to germinate with little to nothing to show for it? Though this doesn’t necessarily save you much time, it can be a good indication that your cannabis seeds are damaged, or just too old to thrive. So if you try to plant some weed seeds and get no sprouts, or find that you have a few that come up, only to self-exterminate before they reach any reasonable size, then you might want to just toss what you have left, because chances are pretty good that they have in some way gone bad, which means that they aren’t any good for growing plants.

5. Size

This happens the most often when friends circulate cannabis seeds among themselves, as professional producers would never release a batch of product with such an obvious flaw, but you might be surprised how much the size of your pot seeds can tell you about whether or not they will sprout. Even if your weed seeds have no visible damage or discoloring, they could be smaller, and this is caused by anxiety-ridden cultivators who rush to pull off a crop that’s been pollinated, resulting in tiny, not quite formed cannabis seeds. Since these little guys haven’t had the chance to finish growing, they are unlikely to ever sprout, which is why size can be a good indication of bad quality pot seeds.

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.
