If you have more questions about strains or seeds, keep digging through Leafly’s resources. And to learn more about the variety of feminized seeds available to you, visit Kannabia’s website to see its full line of feminized genetics, including strains like Diesel Glue and the award-winning Mataro Blue.
Anyone who’s ever savored a joint owes their enjoyment to the fruits of the cannabis plant, but moreover, to the female of the species. That’s because only female cannabis plants produce the cannabinoid-rich flowers that deliver the flavors and effects consumers look for.
That efficiency is key for medical cannabis patients and hobby growers. Since most cannabis regulations limit plant counts, growers cultivating a small crop of cannabis for personal use want to ensure they’re getting the most out of their grow.
How Are Cannabis Seeds Feminized?
Cannabis plants that are pollinated naturally or with traditional breeding techniques can produce both male or female seeds. These are known as regular seeds and, as in most species, they occur with about an even split between the two sexes. That means cannabis cultivators starting with standard seeds have about a 50% chance of yielding a female plant from each one.
This is why many North American growers are turning to feminized seeds—cannabis seeds that carry only female genetics, and can be relied on to produce only female plants. By creatively applying technologies to seed feminization, modern breeders like Kannabia can ensure female genetics in seeds with a nearly 100% success rate.
Once those plants are old enough, growers have to go to the trouble of actually determining their sex, monitoring each individual plant to ensure any males are removed before they can pollinate their female counterparts.
Traditionally, the solution to this has been an inelegant one, with many cultivators planting at least twice as many seeds as they hope to harvest with the assumption that about half of them will be useless. However big a harvest you’re looking for, using regular seeds means you’ll have to plant twice that many seeds.
“a lot of smugglers and heroin junkie speak bad about you…” About Sensi Seeds? See my comment above. Me personally? I seriously doubt my reputation is that big.
Hello Calz, thank you for your comment.
The vast majority of Sensi Seeds genetics are exclusive to us, though we are aware that other strains have been created with them, so there is no need to try to create exclusivity. If we only sold feminized seeds, as some seedbanks do, that could be interpreted as trying to create scarcity, but at the time of writing we still have far more regular strains (39) than feminized ones (16) and we have no intention of withdrawing regular seeds from our stock. Our regular seeds only come in packs of ten, for the reasons you have mentioned.
Old and new methods for breeding feminized seeds
Anybody who has ever used cannabis owes their delight to the female aspect of the plant. This is because female cannabis plants contain greater concentrations of the much-loved cannabinoid, THC. For this reason, growers separate male and female cannabis plants to protect the females from pollination. Feminized seeds remove the need for this kind of “sorting”, as plants are basically guaranteed to be female.
Can seeds be used from stress induced hermaphrodite pollinating itself? Would these have more tendency to hermaphrodite vs using this pollen on another non stressed female?
Would have been good to see something included about the fact using them as mothers may produce intersex clones while limiting (bottle-necking) genetics meaning less chance of finding a keeper pheno.
I found one seed from my medical marijuana and germinated it and planted it. Is there a way of knowing what it will be sooner than later? And where would the seed come from? What are the chances it is female?
Feminized seeds are the “easiest” seeds to grow after the Auto-flowering varieties. Feminized seeds mean that they are treated to make them female (hence the name feminized) so that all the seeds can be used to get flowers. Breeders usually sell feminized seeds for their strains because they are easier to grow and are too unstable to reproduce, although some people use plants from feminized seeds to get cuttings, it is advisable that they use females from Regular seeds. It is recommendable to start growing with Feminized seeds, this will mean that the final plant won’t have any undesirable surprises like seeds reducing potency since there are no male plants.
