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!
How To Tell If A Weed Seed Is Good?
Every cultivator knows how critical seed quality can influence the growth outcome. If you get duds, they won’t sprout. Some bad seeds will germinate but won’t reach their potential yield. It’s essential to know how to tell if a weed seed is good if you want your cultivating efforts to pay off.
Join us as we explore the characteristics of seeds and how to differentiate the good ones from the bad. We’ll also show you how to select the right vendor and where to buy quality seeds, so you get value for money and a bountiful harvest.
Let’s start with answering the question, what do good weed seeds look like?
How to tell if a weed seed is good
If you buy your seeds from reputable seed banks, you can be sure of getting quality seeds almost all the time. You’re more likely to get poor seeds from your local dealer. However, if you know how to tell if a marijuana seed is good, you can rule out bad ones immediately.
One way to judge the quality of cannabis seeds is by looking at their appearance. Be aware, though, that seeds from the same plant can have unique characteristics, just as with human siblings. Quality seeds will differ visually.
What do cannabis seeds look like? Here’s a summary:
- Color – ranges from green to brown
- Shape – some are spherical while others are pointy
- Size – there are small and large seeds
Now, let’s find out how to tell if a marijuana seed is good. Here are a few signs you can look for:
The appearance of weed seeds can indicate their quality. Typically, the outer shells of superior cannabis seeds have dark colors, such as black, brown, or grey. Avoid seeds with lighter hues—white, pale green, and yellow are of poor quality.
High-quality cannabis seeds will not have damaged shells. There won’t be cracks that expose the inside of the seed. You’ll also notice a healthy waxy coating when you look at the seeds under bright light.
While appearance offers a guide, it’s not a reliable indicator of a seed’s quality.
Shape and size
Healthy marijuana seeds may differ in size but look alike in terms of shape—they’re round or symmetrically shaped like a teardrop. Poor quality seeds usually have deformed or flat shells.
Seed size varies between cultivars. Larger ones are easier to grow because they have more stored energy and can potentially develop into healthy plants.
The weight of the seeds also matters when evaluating quality marijuana seeds. If you have two seeds and the smaller one weighs more than the larger seed, the former is of better quality. The bigger seed is lighter because it loses moisture and nutrients as it ages.
Darker high-quality cannabis seeds are hard when you touch them. To feel how firm a seed’s shell is, without using excessive pressure, squeeze it with your thumb and index finger. If the seed doesn’t crack or bend, it’s viable.
Bad marijuana seeds are usually supple or soft. It’ll save you time and effort if you identify them and exclude them at the onset.
Your cannabis seeds will degrade over time, so it’s important to choose freshly harvested ones up to four months old. If you preserve them well, healthy marijuana seeds can remain viable for some time.
It’s impossible to know a seed’s age unless it’s from your own plant. When buying seeds, you probably won’t know the age unless you buy them from a seed bank known for quality genetics. Check the data they provide.
Having inspected the seeds by sight and touch, a quick way to separate viable seeds from bad marijuana seeds is to do a float test. Fill a glass with distilled water and drop in the seeds you intend to germinate.
Check after an hour. Germinate the seeds that sink. Most growers dispose of the floaters as they probably won’t sprout. Even if they do, it’s unlikely you’ll get a healthy plant.
If you want to know how to tell if seeds are viable quickly, use the float test.
Suppose you don’t have time to inspect every seed for viability, germinate all your seeds and watch what happens. You can put them in soil or use other germinating methods. The quality of the seedlings will tell you if you’ve used healthy marijuana seeds.
The challenge here is wasting precious time using this method because you only see results when the germination process is over.
What does a healthy marijuana seed look like?
There are several ways to determine the viability of your seeds. One is by looking at the color of the seeds—healthy marijuana seeds are usually brown with varying shades from light to dark. You may also come across seeds with tiger stripes or turtle-shell patterns.
Seed colors may change due to genetics or environmental conditions, but they’re healthy if they remain in the range. It’s when they display a greenish shade that you have a reason for concern.
They’re not bad marijuana seeds per se, but green hues are a sign that the seeds did not have time to develop properly. There’s a high risk that these seeds will not germinate.
Another way to identify healthy marijuana seeds is to look at their size and weight. If they meet the color criterion, bigger seeds are usually healthier because they’re packed with nutrients and energy. However, you may have smaller seeds that are more viable if they weigh more than their larger counterparts.
Healthy marijuana seeds typically have a body shaped like a teardrop. If you notice seeds that are flat or distorted, they may have a genetic flaw. You’ll have issues germinating them, and if they do sprout, they’ll produce plants that are below par.
Another clue that’ll show that you have healthy marijuana seeds is the appearance of their shell. Good seeds will have shiny-looking shells as though there’s a layer of wax on them. Avoid seeds that look dull and have a matte finish.
How long are cannabis seeds viable?
Now that you know how to tell if marijuana seeds are healthy, the next question is how long are cannabis seeds viable?
The short answer is, it depends on how well you preserve them. Weed seeds get the signal to sprout when there’s heat and moisture. According to some cultivators, if you store your cannabis seeds in a dark and dry space, they can stay viable for as long as 5–10 years.
Pro tip: place a cotton ball with your seeds to absorb excess moisture.
Fresh, healthy marijuana seeds will germinate quicker than older seeds. While you can keep seeds viable for years, some of them may not sprout. The longer you preserve them, the fewer seeds will be productive.
Choose healthy marijuana seeds that are less than a year old. Some established seed banks may indicate the age of the seeds.
If they don’t, you can use the touch test that we mentioned earlier. Squeeze the seeds lightly with your thumb and index finger. If they’re firm, you’ve got young and healthy marijuana seeds. Older seeds may feel soft crack under pressure.
Where is the best place to order cannabis seeds?
Where’s the best place to order marijuana seeds? If marijuana is legal in your state, you can get your seeds from dispensaries or buy them online from seed banks. The latter may be your only option if state laws prohibit the sale of cannabis.
When buying seeds from dispensaries, be sure to check that their staff knows how to tell if a marijuana seed is good. If you’re not happy with the answers you get, you’re better off looking elsewhere.
You should do the same when shopping online. To get high-quality cannabis seeds, we recommend that you only buy them from reputable seed banks such as Homegrown Cannabis Co.
Stay away from small dealers that offer cheap seeds. There’s a high chance that you might end up with duds or low-grade seeds. It’s better to pay a bit more for quality marijuana seeds than endure the heartache of seeds that don’t sprout.
Most recognized online cannabis seed providers offer seeds at competitive prices. We have regular promotions such as Buy-One-Get-One (BOGO), which are money-savers. You get two packets of seeds for one price.
Established seed banks like ours offer a seed replacement guarantee because we stand by the quality of our marijuana seeds. If you have seeds that don’t germinate, we’ll replace them once at no cost.
Another reason to buy from reliable vendors is that they usually have an extensive collection of high-quality cannabis seeds. You’re likely to find the strain you want without searching many websites. Your order and private details are also safe because they have secure payment systems.
3 tips on how to get high-quality cannabis seeds
If you want healthy marijuana plants, you need to grow high-quality cannabis seeds. Sub-par seeds will only cause you to waste time and money because most won’t germinate. When they do, you end up with crops that don’t live up to their potential.
Getting high-quality cannabis seeds may not be as tricky as you think. Here are some tips to improve your odds of having seeds that’ll give you the crops and yield you want.
Choose the right supplier
Buying your seeds from an established seed bank is a reliable way to ensure you get only quality marijuana seeds. Most of these vendors pride themselves on providing customers with the best seeds. Homegrown offers replacement seeds if they don’t germinate.
You have a wide range of cannabis seeds to choose from. If you want sativa or indica cultivars, these seed banks will likely have the strain you want. Some may even have hard-to-find ones.
Get professional advice
When buying high-quality cannabis seeds, you want to know as much about them as possible. Reputable sellers have weed experts who prepare detailed information about the seeds and answer your questions.
These professionals will also advise you on the type of seeds that are suitable for your cultivation goals. You don’t need to figure out for yourself if you should grow regular, autoflower, or feminized seeds.
Create your own seeds
You can create high-quality cannabis seeds if you want to, but it’ll take some knowledge of the subject. You need to pollinate the flowers of your cannabis crop. To do so, you need the male part of your plant to send pollen to the female, which has flowers.
Except for plants grown from feminized seeds, most have both male and female parts. If you want to produce your own quality marijuana seeds, you should choose regular seeds.
Before you act on this knowledge, make sure you understand your state’s weed laws. Some states still prohibit the home cultivation of cannabis. If yours is one of them, don’t despair. Not being able to grow pot doesn’t mean that you can’t buy quality marijuana seeds.
U.S. Federal law allows citizens to purchase seeds as souvenirs. You can preserve them until it’s legal to cultivate in your location, as long as you don’t germinate them.

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.
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.
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.
