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.

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.

Should Cannabis Seeds Sink or Float?

So as a grower you just bought your new cannabis seeds. Now you need to grow these seeds and have heard of the sink and float method of cannabis seed germination.

This is a very simple method used to start to see if the seeds that you bought or were given to you are going to germinate before you put them in the soil.

Science behind Cannabis Seed Viability the floating water test

In nature cannabis seeds are food for many animals big and small. They are also a great protein source for insects. Once the seeds are eaten by the insect, they will get inside the seed, it will no longer be able to absorb water. Therefore the seeds will float.

Not all seeds will work for these methods however cannabis seeds are one of those types of seeds.

Experiments With the Sink or Float for Cannabis Seeds

In tests the average of all tests showed a germination of 68.3 per cent for sunken seeds and 72 per cent for those that floated. In a second set of experiments, it was found that 75.4 percent of the sunken seeds and 86.7 percent of those that floated germinated. Pretty cool stuff, however it shows that the cannabis seeds sink or float method is not always 100% fool proof.

Where to find cannabis seeds to grow online

There are many places to buy cannabis seeds online, we recommend Green Avenger Seeds if you are looking to buy cannabis seeds online. They have great seeds to use for trying the sink or float method of cannabis seed germination.

What do cannabis seeds need to germinate

When germinating cannabis seeds it all comes down to the right amount of warmth and moisture that is provided for the seed. As a new grower you will be looking for seeds that are dark brown in color, they may have stripes on them. Cannabis seeds that are not mature will look white, green, or even gray in colors.

The seeds should be firm and not have any cracks in them. If you push on them gently they should not break in between your fingers.

How to add your seeds to water

First take your new seeds, then fill up a glass of water about half full not half empty (LOL). The water should be clean and have a neutral PH of about 6.5 to 7.0.

For a bonus you can add a drop of Superthrive, and also a teaspoon of kelp (Seaweed extract), this will really give the seeds a jump start as the kelp contains growth hormone that will activate the cannabis seeds.

Place you seeds in the dark

Now you are ready to cover your seeds and place the glass in the dark for 24 hours. The glass with the seeds should be in a warm spot that is dark for best results.

Now Check if your Cannabis Seeds Sink or Float

After 24 hours comes the big moment, you can remove the glass of seeds from the dark and check on them, you should see the viable seeds floating at the top of the glass. They should start to have a sprout growing out of them. If they do not you may want to place them back in the dark for another 12 hours.

The Cannabis Seeds that were not viable, will have sunken to the bottom of your glass in the water.

Planting your Floating Cannabis Seeds

Now that your seeds are floating that means that you can now plant them in your soil mix.

Gently remove the seeds from the glass with tweezers and make sure you place the germination sprout that has emerged for the cannabis seed facing down in the soil. This new young sprout will push its way down into the soil and at the same time push the seed and the first young leaves above the soil.

Growers achieve 100% Germination rates with the Cannabis Seed Sink or Float method

This seed starting method works very well and you will normally get a perfect germination rate with fresh cannabis seeds.

Why Use the Cannabis Seed Sink or Float Method

When starting seeds directly in the soil, you really don’t know if they will be viable or not. With the Cannabis Seed Sink or Float Method you know that the seed has already germinated.

This process takes the guessing game out of the process, you know that within a day to a couple of days your seedling will break ground.

There are many other ways to germinate cannabis seeds and we will be covering more.
