10 Markers of a Quality Marijuana Seed

If you’re looking to start growing your own marijuana, the first place to start is with the seed. What should you look for? How can you tell a good cannabis seed from a dud? Chris Bond tells us.

So, you’ve decided to grow your own marijuana from seed. How do you know if those little, round nuggets in your hand will grow up lush and produce beautiful, productive buds? How do you know if they are duds? While ultimately the genetics will determine the destiny of those little weed seeds, and proper care will help them to realize their full potential, there are some markers you can assess to see if what you have is quality seed, indeed.

What to Look for in a Cannabis Seed

#1 Color

While all cannabis seed is not identical in color, there are some consistencies. Healthy, viable seed will be light to dark brown in color. Seed that is light green or even whitish in color is underdeveloped and should be tossed out. Healthy seed will also have a burled or turtle shell-like pattern on its seed coat.

#2 Sheen

A quality cannabis seed will have a waxy, protective coating. Seeds that appear dull are probably not as viable and should be avoided if given a choice.

#3 Shape

Quality cannabis seed will look like a plump teardrop. Flat or misshapen seeds will not likely produce quality plants.

#4 Texture

Quality seed will be firm. Cannabis seed should have a strong seed coat protecting the pre-emerged life inside. Any seed that is tender, pliable or squishy should not be planted; poor results will follow if attempted.

#5 Size

Size is relative, but if you are able to compare several seeds at once, the higher quality seeds are larger. When it comes to seeds, less is more. The fewer seeds that comprise any given amount, an ounce or a gram for example, is generally an indicator of higher quality seeds. The biggest seeds within a species generally have more energy stored within them and have a greater potential to mature into a productive plant. Note that indica strains tend to produce larger seeds than sativa strains so make sure the comparison is made among like seeds.

#6 Weight

Weight often goes hand-in-hand with size, but heavier seeds are generally of higher quality than lighter ones. The older a seed gets, the more potential loss of moisture and nutrients, reducing its overall weight. Damaged seed, which has been cracked can potentially lose those same necessary qualities.

#7 Float test

Quality seeds will sink in water. In glass or vessel, place room temperature water deep enough to full cover the volume of seeds to be tested. Place your seed or seeds in the water. After a couple of hours, anything still floating, should not be considered a quality seed. Soaking seeds will allow moisture to cross over the protective membrane and signal the seed that it is time to grow. As such this test should not be performed if the intent is to store the seeds after testing as it may render otherwise quality seed unviable if not meant to be immediately germinated afterwards.

#8 Storage

You may not have access to see or have verified information on the storage conditions of seeds, but if you can find this out, it is critical to maintaining quality seeds. While cannabis seeds can be viable for over 10 years in some instances, the best seed in terms of productivity is not more than 12 to 18 months old. It should have been stored in dark, cool and dry conditions to prevent mold or the onset of any fungal issues. Storing in a freezer can prolong seeds as well, essentially suspending time.

#9 Age at harvest

This is another aspect you, the buyer may not be privy to. Quality seed is harvest when fully mature. If seed was collected before the plant was able to load as much stored energy into it as possible, then that seed will be starting out life in a deficit. Color, as referenced above can be an indicator of whether or not a seed was harvested at the appropriate time.

#10 Cost

You get what you pay for and a cannabis seed is not exempt from this maxim. Quality seeds are not cheap (at least when compared to other agricultural seeds). This isn’t to say that inferior seeds can’t be overpriced, but if you find cannabis seeds proclaiming excellent genetics for sale at a price that seems too good to be true, caveat emptor.

This is not meant to be a definitive list, as new varieties of cannabis emerge on the scene all the time that may have “normal” traits that would otherwise be viewed as deficiencies in other strains. As always, do your homework, ask other growers who know and buy your seeds from a reputable source.

What Do Weed Seeds Look Like?

It’s important to know what to expect and what to look out for before you buy cannabis seeds. In addition to important factors such as sufficient water, nutrients and light quality, a successful crop starts with high quality healthy cannabis seeds. But how do you determine whether a cannabis seed is healthy, viable and of high quality?

The quality of a seed can be partially assessed by looking at the appearance. However, you have to know what a healthy cannabis seed looks like and that can be difficult. Even for the experienced grower. In this blog we therefore answer various questions such as: what do weed seeds look like and how can you see if a cannabis seed is healthy and viable?

What do female weed seeds look like?

Some people believe you can see the gender of the strain based on the appearance of the seeds. Well, we can tell you that ain’t possible. Both female and male seeds look exactly the same.

What do healthy cannabis seeds look like?

Healthy cannabis seeds are sufficiently matured and therefore have a different appearance than unripened cannabis seeds. For example, viable cannabis seeds meet a number of criteria. Think of the size and shape, hardness of the outside and color.

Color of the cannabis seed

Fertile cannabis seeds are black, dark brown, red-brown or gray with a shiny glow as if there is a bit of wax on the peel. Cannabis seeds with a different color such as white, yellow or light green will probably also germinate, but indicate lesser quality. Such seeds have been harvested too early and haven’t had enough time to ripen.

Tiger stripes

Although it isn’t always visible with the blind eye, on a quality cannabis seed you can see a pattern of “tiger stripes” or dark spots.

Shape and size of a cannabis seed

Cannabis seeds have a unique shape. They are oval, have the shape of a drop and are small in size. On average, a cannabis seed is about 2 to 5 mm long and 2 to 3 mm thick. If you want to know what you can expect in advance, then we can advise you to take a look at the seeds of a tomato.

Hardness of the peel

A well ripened cannabis seed had sufficient time for hardening its shell. Healthy cannabis seeds are therefore provided with a hard smooth skin without cracks. You can test the hardness of the shell by taking the seed between your fingers and applying gentle pressure. Immature seeds will easily crack or crumble while qualitative cannabis seeds won’t damage.

Note: the moisture from your fingers can damage the seed. Please use linen gloves to prevent this.

Float test

To test the viability of a seed you can place the seed in a glass with distilled water. Seeds that sink within 2 hours have sufficient mass. These seeds generally have a better chance of sprouting than seeds that still float.

Note: this test isn’t 100% accurate and only provides an indication of the viability. In addition, the water will activate the germination process. Therefore, only carry out this test if you want to germinate the seed immediately. After performing the float test, you can’t longer store the seed.

How do Cannabis Seeds Work

How do cannabis seeds work? You might not think that this is important, but knowing how seeds work can give you important insight on how to store them and what the germination profess involved. Cannabis seeds are technically small, oval-shaped dried fruit, around 3-4mm long and 1.5-2mm wide. They’re covered in a very subtle membrane, and underneath that layer there’s a much harder layer which is the largest system of the embryo, covering it and protecting it.

On the inside of the seeds you can find a substance called albumen, which is a nutritional reserve that keeps the embryo healthy until germination; it’s also the seeds initial source of energy once it begins germinating.

Now, for the center of the seed, home to the precious embryo from which your new plant will grow from. It contains the plant’s genetic code alongside four other parts; the radicle, the hypocotyl, cotyledons and gemmules. The radicle is the embryonic root; this is the part of the seed where roots come from. The hypocotyl is known as the embryonic stage, and the cotyledons are in charge of those first few leaves that you can see once the seed germinates.

Cannabis seeds, just like many other plant seeds, grow in pollinated flowers on female plants; seeds only contain the plant’s genetic code, so they don’t have any of the active principals in the plant, meaning that if you were to smoke it you wouldn’t get any sort of psychoactive or medicinal effect. They can be eaten however, as they provide an enormous amount of beneficial proteins, including Omega 3, 6 and 9. The aroma that comes from the seeds when burning isn’t pleasant at all, and if you’ve ever been smoking a joint that had a random seed in it then you know exactly what I’m talking about; they taste like some sort of burnt barbecue that ruins the taste of even the best, strongest tasting weed out there.

Germinating seeds correctly depends on different factors; the main one being how mature the seed is. Seeds that look too white, green or the skin seems to be coming off or not there at all tend to be too young still, although there are seeds of this stature that will germinate perfectly, depending on the strain. Strains like Somango, or hybrids that come from it, and Haze seeds are some of the whitest seeds you can find on the market; sativa seeds tend to be much smaller than indica seeds, like Thai seeds are generally much smaller than afghan seeds. In this case, size doesn’t matter at all; if a seed is smaller than others that doesn’t mean that it’s going to have issues germinating or that it will grow smaller plants. Smaller seeds generally have less protection, but they’re much easier to germinate. Seeds can take between 3-18 days to germinate depending on the conditions such as temperature, humidity, substrate composition etc. The longer the seeds take to germinate, the less likely that they are going to germinate. Sometimes if after a while it still hasn’t germinated, you can gently squeeze the seed to break the outer shell and if done right, you can help the root to leave the shell; if done wrong, you’ll end up completely squishing the seed and any chances of germination that it had.

During the time the seed is maturing various factors need to occur for the seed to be able to germinate in the best conditions. Seeds have a germination period of three years, which is the average time estimated that seeds can be kept in good conditions; it’s not the same to keep your seed in a fresh, dry area than in a hot and humid one. Humid areas will damage seeds, stimulating their metabolism with the humidity without stimulating germination which could even kill the seed off entirely. Water absorption is due to the water potential difference between the seed and its surroundings. Water reaches the embryo through all of the layers of the seed, which then activates the development of the radicle; once this process begins, seeds need more oxygen than water, so giving your seeds too much water might in fact “drown” them. This is why we highly recommend not germinating your seeds in glasses of water, as the oxygen-water ratio is nowhere near optimal for germination.

By lowering oxygen levels as well as temperature storage levels you can increase the life-span of your seed for up to 20 years. Another storage technique is to dehydrate the seeds around 2-5%; no more is recommended as it might affect the internal constitution of the seed. Temperature is extremely important as it regulates the activity of the enzymes during germination; during storage, temperature regulates the embryos metabolism.

Oxygen is found in nature in a concentration of about 21%; seeds tend to germinate in conditions with around 20-21% oxygen, and hardly any seeds can germinate with a lower concentration than that; the only plants that can really do that are marine plants and algae, which need 8% oxygen.

Now that you know how cannabis seeds work, you can store your babies for up to 20 years if you want to, and give them the perfect conditions in which to open up their shells and let the radicle take over growing the roots. Happy growing!
