Today, anyone can buy marijuana seeds online, but how can you tell if they are good? Here are a few tips to help you avoid making a mistake

Interest in cannabis seeds has grown considerably in recent years.

Many people buy cannabis seeds online and elsewhere for a wide variety of purposes. Despite this, most buyers still don’t know how to tell if marijuana seeds are good or not.

It is why here on our SensorySeeds blog, dedicated to cannabis seed enthusiasts, we thought we’d take a closer look and provide some must-have tips on how to distinguish quality seeds from inferior merchandise.

The first tip?

Assess the quality of the seller…

Here at SensorySeeds, we give a 100% guarantee for the products in our shop, and our customers can be sure that they are getting good quality marijuana seeds at fair and competitive prices.

We will now go into what the quality of a seed depends on and how to check it. Still, first, we would like to point out that although buying and storing cannabis seeds in the UK is perfectly legal … but growing them is not! 

So, this article is in no way an invitation to do this or any other illegal activities due to buying our products.

How to find if marijuana seeds are good

What to do to find out if your seeds are good

You may have doubts about seeds you bought some time ago and don’t know if they are still alive.

Whether they are marijuana seeds or seeds in general, several available methods can determine whether the seeds are still good.

Generally speaking, we can say that most seeds manage to last several years, but this also depends on how they are stored. If a seed is not stored correctly, it is very likely that it will go bad very quickly and will no longer be usable in any way.

What you must absolutely avoid when preserving your seeds is to overexpose them to light and moisture.

In this case, the seeds would risk sprouting, rotting or drying out, as the case may be, and you would have needlessly wasted your money.

Therefore, it would help if you stored them in a cool, dry place, preferably in their original packaging or in an airtight container, preferably one that allows excess air to escape.

If you still have doubts despite having followed these precautions, you can do some simple tests.

Let’s see what they are:

  • Water test: This is an elementary test. Just put your seeds in a container full of water and let them stand for about 15 minutes. If the seeds sink, they are still viable. If they float, they are probably dead because they contain air. However, this test is not 100% safe, so not everyone uses it.
  • Germination test: Take the seeds, or at least a dozen of them, and place them in a row on a dampened paper towel. Fold the paper towel to cover them, put it in a zip-up plastic bag, and seal it carefully. This way, the napkin will remain moist and protected. Then put the bag in a warm but not too warm place, for example, on top of a cupboard or the fridge. The seeds should be checked often, at least once a day, to see if they can germinate and check that the napkin is always damp. If it is too dry, you can water it a little more, but avoid overdoing it. You should also keep the bag away from direct sunlight.

In about two weeks, the seeds should start to germinate, but it is best to find out the timing of each seed so that you do not give up too soon.

Once the right time has elapsed, you should check how many seeds have managed to germinate.

If less than five have germinated, then most of the seeds have probably gone wrong, but if more than 5 have germinated, then the seeds are still good.
