How to Tell if a Cannabis Seed is Good

Got a cannabis seed, but you’re not sure if it’s any good? No worries. By the end of this article you’ll know everything you need to get started.

The legality of growing cannabis varies depending on where you live in the world. Know your laws.

What to Look for in a Healthy Cannabis Seed:

You can tell a lot about a seed’s health just by looking at it. Here are a few different things you should look for when deciding if a cannabis seed is good or not.

  • Darkened Color – Good cannabis seeds will be brown, black, and/or gray. White or green seeds are immature and unlikely to sprout. Your seed should also have stripes or spots all the way around.
  • Waxy Coating – A healthy seed will have a thin waxy coating around it. This coating should appear to have a slight sheen to it.
  • Hard Shell – You should be able to lightly squeeze a seed without it crushing. If a seed crushes easily between your fingers then the seed is likely dead or weak and will not grow well.
  • No Cracks – Inspect the entire seed to make sure there aren’t any small crack or holes. This will most likely cause the seed not to sprout.

Ways To Test Cannabis Seeds

Now that I’ve gone over a basic guide for what to look for I’ll give you a couple of ways that you can test your seeds.

Test Method #1: Floating Seeds in Water

This is a great test that works for many different seeds – not just cannabis. Take your seeds and drop them in a cup full of warm (not too hot) water then wait a couple of hours. If they sink then they’re probably good to go. If they won’t sink then they are probably dead and won’t grow.

Note: Only do this if you’re ready to germinate your plants. Otherwise, it could harm your seed. I cover germination in a later section.

Test Method #2: Just Go Ahead and Try to Germinate the Seed

I know this seems obvious, but it really is the best information I really could give. If you really want to know if a cannabis seed is able to germinate then go ahead and try germinating it – what do you really have to lose? Not quite sure how to germinate a seed? No worries. Here’s a quick guide:

How to Germinate a Cannabis Seed

Germinating a seed simply means getting the plant to sprout from the seed. It’s the first step in your cannabis seed’s journey to a full grown plant. There are several ways to go about this.

One way is to simply plant it in your soil and see if a plant pops up. It’s old school, but no one can deny its simplicity. Plant the seed about 1/4″ deep and wait.

Another way is to put the seeds on a damp paper towel. Make sure the paper towel is damp, but not soaking wet. If it dries out you can add a few drops of water to the paper towel. Leave the paper towel in a dark place. The amount of time is going to vary among strains. Some may take only 2 days while others could take longer. Continue to check them once a day.

How to Tell if a Cannabis Seed is Male or Female

Unfortunately, there is no way to know if a cannabis seed is going to be male or female simply by looking at it or doing a simple test. This is a bummer since most people don’t want male cannabis plants in their garden.

If you want feminized seeds then you’ll have to buy them from a reputable seed bank. Make sure they say feminized – if they don’t say it then they probably aren’t.

If all you’ve got is a bag seed then the only way to find out if it’s going to be male or female is to grow it.

Can My Cannabis Seed Go Bad / Expire?

The short answer is yes, but if you store your seeds properly they can stay viable for years and years. Moisture, UV degradation, and extreme temperatures could all affect the quality of your seeds.

If you plan to store your seeds for a long period of time make sure to keep them in an airtight container in a dark area. Ideally, seeds should be stored in a climate controlled area (like inside your house instead of in a shed or garage. One study showed laboratory-sealed cannabis seeds were still viable after 19 years.

Conclusion

It’s nice to know what to look for, but in the end the best test is just to put it in soil. If you’re using bag seeds then you never really know what you’re getting anyways. If you’ve bought your seeds from a legitimate seed bank then you shouldn’t have to worry about it.

Dead Germinated Seed?

So, I first want to say thanks to everyone here who is always helping peolpe with their questions. I’ve read many forums and threads and without you guys’ help I would be even worse at this. I’m a COMPLETE Noob and this is my first grow ever.

I got 3 LR2 x AK47 seeds from Attitude and germinated 1 of em (Paper towel method). I then got a 8 1/4″ pot, which I think may be entirely too big, after filling it with Fox Farms Ocean Forest and watered thoroughly (all extra drained water I disposed of) then I put the seed about half an inch under the moist soil and put it in my closet. There’s a fan that cirulates air and the light was put about 2″ from the soil. First day after 18 hour light with a 125Watt 5u CFL, nothing. Second day, nothing, but I looked at the seed and the taproot was green but the tip was a light brown. This morning after another 18 hours, the seed shell is a light brown, and the plant inside the shell looks crispy almost. I moved the light a few inches away from the soil after making sure the soil was moist again (Seed was taken up anyway to see its “development”) I’m not sure if this is overwatering or heat? I tried to make sure to have a balance, but the top of the soild and about an inch down just seemed so dry.

I think it is both overwatering and the light being way too close.

Forget the paper towel, just pop the seed in damp soil and leave it alone – too many seedlings are killed by growers – they know how to grow without us screwing them up

So lets say I moved the light up and I don’t water for 2 days, can it work itself back in a groove or is it too far gone and time to germ another. Also did I add lights too early? I turned them on right after planting it, like 3 minutes afterwards, and for a full 18 hour cycle.

A plant doesn’t need light until it’s seed cap falls off and having light before that can stress the plant. Leave it in darkness to germinate and pop out of the soil. Once it’s first leaves unfurl, then add light.

Over watering can cause all sorts of problems for seedlings. It sort of sounds like it got rotten from the moisture and heat. I’d let your pots dry for a nice long time and only water them when the plants are showing signs of dryness.

OK thanks guys! I hope I turned everything off in time for it not to die. OK, fans and lights are off in my closet.. Has Humidity of 50% Temp of 77 degrees F. Just leave it in there and wait for it to grow outta the ground? And how long would this usually take? I wouldn’t want to add light again, too early.

OK, well now the whole thing is brown. I’ll leave it. but in the mean time.. If I germ another seed, how long until I put it under the 18 hour light cycle?

scrap the seed, you killed it. Germ another and DO NOT use lights until it is fully out of the soil, then you can start the 18/6 cycle.

How to tell if a seed is dead? Here are some tricks

Sometimes hemp seeds do not germinate because they are lifeless. Here’s how to spot a dead hemp seed and avoid wasting time

In previous articles, we have repeatedly stressed how the quality of cannabis seeds can make all the difference in achieving a healthy and productive plantation.

Poor quality seeds can lead to weak and unprofitable plants or even to no germination at all.

This article will learn how to recognise quality hemp seeds (such as BSF seeds) and tell if a seed is dead and therefore totally useless.

Dead or bad hemp seed: here’s why quality is essential

In the field of hemp growing, some choose to buy ready-made seedlings, and those prefer to plant the marijuana seeds themselves so that they can monitor the growth of the plantation from the very beginning.

Of course, in order not to waste time, it is essential to make sure that you are dealing with quality seeds of the right genetics (such as auto-flowering seeds, feminised seeds, etc., which you can find for sale at SensorySeeds), but above all, they must be alive!

Yes, you got that right!

If the seeds are too old or have been stored incorrectly, they may have lost their ability to germinate, and so, even if you put your mind to it, the seedlings won’t grow.

In the next section, we will clarify the main signs that the seeds you have in your hands may be lifeless.

Dead seeds: how to recognise them?

Many novice cannabis growers are tempted to buy low-quality marijuana seeds because they are sold cheaply.

Up to this point, it all seems quite normal. However, in such cases, the problem is that the seedlings often do not grow, and it isn’t easy to understand the cause.

Many people wonder what they might have done wrong and try to figure out what to do if the seeds do not germinate.

Of course, sometimes you make mistakes, but you have to check whether the seeds you have bought are still alive in other cases.

Knowing how to distinguish high-quality seeds from bad ones is very important to avoid wasting time and money.

Let’s start with the appearance.

Good quality seeds usually have a kind of waxy layer that shines when exposed to light. As a result, their colour can vary from brown to grey or black, with some speckling.

If you are dealing with white or light green cannabis seeds, they are immature and unable to germinate.

Seeds that appear ‘dried out’, have cracks or dents are of poor quality.

You can also tell by touch whether the seeds are good or not.

If you hold a hemp seed between your index finger and thumb and apply pressure, some seeds crumble, while others do not at all. The quality ones and the ones most likely to be alive are, of course, the latter.

A test is considered almost foolproof to see if hemp seeds can germinate: water immersion.

If by putting them in a glass with warm water they float, then it means they are dead or rotten; whereas if they go down, they are of good quality.

Of course, all these tricks apply to seeds of all genetics and types.

If we have intrigued you, you too can try floating feminised seeds, fast seeds or auto-flowering seeds from your collection (but remember that growing cannabis is not allowed in the UK).

Concerning the flotation test, however, we would also like to point out that it should only be carried out during the hours before sowing and that the seeds must be removed from the water within 24 hours. Otherwise, they will be irreparably damaged.

Live seeds which do not germinate: what is the cause?

If also thanks to the advice given above, we know that our seeds are alive but still do not germinate, there is probably another cause.

Let’s see what the main ones might be.

  • Soil which is too cold
  • Sometimes it is the temperature of the soil that is too cold that prevents marijuana seeds from germinating. If you keep the soil warm enough, you will see faster germination.
  • Incorrect choice of substrate
  • It is usually recommended to use a relatively friable and light substrate when sowing cannabis. If the seedlings do not germinate, the root growth may be prevented by too loamy and difficult to penetrate.
  • Sowing too deep
  • Cannabis seeds, being relatively small, should be planted close to the surface of the soil. Otherwise, the sprouts will not be able to emerge.
  • Insufficient irrigation
  • Sometimes cannabis seeds fail to germinate because they are not watered enough.
  • It is essential to keep the soil well moist, as this is the only way for the seeds to swell and germinate.

To conclude

As we have seen, you can use a few tricks to find out if your cannabis seeds are dead or not.

Unfortunately, even if the seeds appear to be alive and of good quality, they may have genetic defects. That is why the best choice is always to buy quality fast flowering seeds (such as BSF seeds) at the outset.
