3. Hardness & Durability
You can identify quality cannabis seeds by their size and shape, especially when you can compare several seeds side-by-side. The largest seeds with the most symmetrical round or teardrop-shape are the best quality, while immature seeds are small and often have an irregular shape.
High-quality seeds have certain aesthetic qualities that set them apart from seeds that aren’t as healthy. The most viable seeds are brown, tan, or even black, as immature seeds are lighter colors like white, yellow, and pale green. Some people even claim that the best seeds feature dark spots or stripe patterns and that there should be a healthy sheen on the surface when held under light, like a fresh coat of wax.
5. Float Test
The best seeds have a hard outer shell with a smooth, uncracked surface, while undesirable seeds have soft surfaces that crinkle, crack, or crumble completely quite easily.
2. Size & Shape
Like with any crop, a successful cannabis harvest starts with high-quality seeds but knowing how to identify the best ones can be tricky even for growers with years of experience. To help give you an idea of what to look for when preparing for your marijuana garden, here we talk about how to identify quality cannabis seeds on sight.

This has been a question that has become a very hot topic online these days. After a quick search, growers can find multiple charts and explanations on how to sex cannabis seeds.
This will mostly happen when a plant is stressed by its environment. When this happens, the plant may think it’s going to die and as a result, will change itself into a hermaphrodite plant. By doing so, it will be able to self-pollinate itself and survive.
Common myths on identifying the sex of a cannabis seed
While environmental factors may not necessarily determine the sex of marijuana plants or cannabis seeds, it is known that certain environments can change the sex of a plant.
While it would be much easier for growers to be able to sex their cannabis seeds, the simple fact is that there’s no way to do it. However, sexing plants early on during their growth period is not only essential, it’s completely possible. Growers can even do it before their plants enter the flowering stage if needed. Then male plants can be removed and growers can enjoy a nice, full crop.
One of the biggest myths of sexing cannabis seeds comes from a popular chart online.
Typically, marijuana plants cannot be sexed until they have already begun to grow. Cannabis seeds will look somewhat identical and plants in the vegetative stage will also look identical,. As the plants move into their flowering stage, they will start to show very clear signs as to what sex they are. While it would be much more convenient for growers to be able to determine sex before this point. The sad truth is that it’s just not possible.
Unfortunately, there is no way of knowing if a cannabis seed is going to be male or female. And just by looking at it or doing a simple test.
Most of the cannabis seeds offered for sale in seed shops are of high quality. In most cases, they exhibit high germination rates of at least 95% and sometimes even higher . On the other hand, seeds from an unknown source may well be defective and eventually lead to the growth of a weak and disease-prone plant with slow growth rate and low harvest potential.
If all you get is a bag seed, the only way to know if it’s going to be male or female is to develop it.
2 test method: just before and try to sprout the seed
If you want feminized seeds, you will need to buy them from a reputable seed bank. Make sure they say they are “feminized” – if they don’t, the seeds probably won’t, or rather randomly. These are the so-called “regular” seeds
The seeds have an expiration date. But if you store your seeds properly, they can remain viable for years and years. Moisture, UV degradation and extreme temperatures could affect the quality of your seeds.
You have a basic guide to distinguish good from bad seeds. Now if the doubt persists, here are several ways to test the seeds.
A healthy seed will have a thin waxy coating around it. This coating seems to have a slight shine.
