Finding a cannabis seed in your stash is not ideal, but we’ve all been there before. Although much less common than it once was, it still happens. Sometimes you’ll notice one when grinding down some flower, or you’ll see one pop, spark, and crackle from the heat of a lit bowl.
Germinating cannabis seeds doesn’t always go as planned. Some seeds will be duds. Others will be slow and take longer to sprout. But some will pop quickly and grow rapidly.
But sometimes you get lucky and find a mature seed in some really nice herb. Strains like the legendary Chemdog wouldn’t be possible without adventurous smokers planting and proliferating the seeds they found in a bag of kind bud.

You can also minimize headaches and avoid the hassle of seed germination and sexing plants by starting with clones.
For a seed to be viable, it must be mature enough to have a completely formed genetic blueprint, and it must be strong enough to germinate and pop through its hard casing and sprout its crucial taproot.
In commercial cannabis production, generally, growers will plant many seeds of one strain and choose the best plant. They will then take clones from that individual plant, which allows for consistent genetics for mass production.
The main drawback to growing from seed is there is no guarantee as to what you’ll end up with—if you buy a regular pack of cannabis seeds, it will be a mix of males and females. You’ll need to sex them out (more below) to identify the males and get rid of them, because you don’t want your females producing seeds.
- Cover the top of the pot with plastic or card to catch pollen as it falls, or modify a plastic drink cup to shroud the plant and catch falling pollen.
- Fix a clear plastic bag, perforated at the top for air exchange, around the whole plant.
- An experienced eye will remove each flower pod prior to it bursting completely open to be sure of catching every spore.
- Pollinating a female is the easy bit. Depending on how many seeds you want to make, there are a couple of methods that can be used.
- Using a watercolour or other fine, soft brush or even a cotton bud, dip into your pollen collection and gently apply to the chosen flower. Although thousands of viable spores will be on the end of the brush, enough to pollinate a whole plant, the trichomes on the surface of the pistils will greedily glue everything you offer them. So dip into your pollen stash a few times as you dust.
- For lots of seeds, put pollen in a bag and put over a whole branch or a whole plant, shake well, and leave for twenty four hours.
- It is possible to pollinate different branches with different pollens and have a breeder plant that has 1, 2, or 15 different crosses on it.
- It is also possible to self-pollinate the plant from which the male parts were created. This won’t produce as many seeds as pollinating a separate plant because less female flowers are produced and many are nonviable because of the feminization process.
Once the plants have been sprayed with colloidal silver and the pollen is collected, they are write-offs—86 them and don’t smoke them. Giving them a thorough rinse will not work. The colloidal silver is a systemic treatment absorbed into the plant through the foliage and not a topical application. Be safe and bin them.
Treat feminized seeds as you would any other seed from germination to veg, and veg through flower. Observation is where it’s at now, you want the best plants for your garden. Ideally, setting up a separate vegetation/flower space where a number of plants can be grown lets your standard grow space continue with uninterrupted production.
GROWING FEMINIZED PLANTS
Wouldn’t it be sweet if it was possible to grow all females from seed, every plant, every time?
Just as with standard male to female crossings (which is a heterozygous process), a number of plants will need to be grown and the best selected for mother plants and future breeding. With enough room, hundreds if not thousands of new plants can be grown in order to select the best of the best phenotypes.
Growing from feminized cannabis seeds is a space and resource-efficient way of getting all girls, all the time. Find out how to create your own feminized cannabis with Royal Queen Seeds.
Well, that is where the feminizing technique comes into play: two methods of manipulating the cannabis plant to produce only females from seed, every-time. To be truthful, it isn’t every single time. But 99% of the time is a pretty good number, and could be considered entirely male risk-free.
Of course, growers want to avoid this phenomenon if they’re aiming for the best flowers possible. We’ll dive deeper into what causes hermaphroditism and how to avoid it below.

Cannabis growers and breeders use this trait to their advantage, since it allows them to separate male and female plants. This enables them to prevent the flowers from becoming fertilised and going to seed, which results in better quality flowers, known as sinsemilla.
IDENTIFYING EARLY SIGNS OF MALE PLANT
When you grow cannabis plants, they will either turn out as females, males, or hermaphrodites, meaning a hybrid of the two sexes. Knowing the difference between the three is vital to maintaining a strong growing operation, whether you’re planning on crossbreeding strains, maximising the yield of your female plants, or studying each of the types.
Male plants, in contrast, don’t produce flowers. This makes them less valuable for growers seeking only buds. However, they do produce pollen sacs. These small vessels create the genetic material required to fertilise female flowers and create hybrids. This makes the males extremely important for breeding new cannabis strains.
If you want to try breeding, you’re going to need regular cannabis seeds, and Royal Queen Seeds offers a premium range. In contrast to feminized seeds that produce only female specimens, regular seeds offer a 50% chance of the plant being male or female.
Growers identify plant sex by identifying pre-flowers, which are small structures that form at the nodes during late vegetation.
