To get the buds found in medical and recreational stores, female cannabis plants are grown in an environment without males—or the males are removed from the area before they release pollen—so the females don’t create seeds. Females can then focus their energies on producing buds and not seeds—this high-potency marijuana is traditionally known as “sinsemilla,” meaning “seedless.”
You might also find a mature seed that has been physically damaged through poor handling, like rough trimming. In those cases, it probably isn’t worth the effort to try and germinate the seed.
Pros and cons of using cannabis seeds
Make sure the area the seeds are in is warm, somewhere between 70-85°F.
This is the beauty of seeds—often, you can tell which plants or genetics will thrive right from the get-go. This will help you determine which plants you want to take cuttings from for clones or for breeding if you want to create a seed bank of your own.
Many marijuana growers start autoflowers early in the season, and at a different time than a regular crop, so keep the season and climate in mind when growing and harvesting—your plants still need warmth to grow, and rain can give them bud rot. Consider growing in a greenhouse to protect them.
If you wonder what do cannabis seeds look like, you might not be alone. Many people wonder the same. Cannabis seeds may be as big as 2mm or as small as .5mm but cannabis seeds will always be whitish-brown and have small black spots on them. Although some strains may look different, you cannot actually tell the genetics or sex of the plant by just looking at the cannabis seeds, regardless of the claims people make.
If you are wondering whether the size of the cannabis seeds makes a difference, they actually don’t. You will get the same result from big or small cannabis seeds and they will grow to become massive plants even if they came from smaller-than-usual cannabis seeds. Remember that what cannabis seeds look like will not define the plant that you grow or ultimately the cannabis you smoke.
What do cannabis seeds look like can’t define any other characteristics of the strain!

Our 15 years in the business have provided us with a great command as well as a wide perspective of this subject, so it is an honour for us to be able to share our knowledge with all of you in the cannabis community.
The same thing happens with cannabis seeds: the packaging and the different stages before they’re commercialised can entail lighting and humidity changes, as well as a bit of oxidation, which may slightly affect the colour of the shell but definitely has no impact on the final product. Once again, this is simply a visual effect.
The size of cannabis seeds
Yet again, this is a misleading physical attribute that does not guarantee the germination potential or overall characteristics of a seed. A high-quality strain can also be light or dark grey in colour.
Critical + is a clear example that colour, contrary to what many growers believe, is not necessarily a quality indicator: these undeniably high-quality seeds exhibit a very light grey, almost whitish grey, to a medium grey colour.
Cannabis seeds can also show slight changes at morphological level. It’s perfectly normal to find minor differences in the oval shape of seeds from the same batch.
