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.
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.
Male vs. Female Cannabis Plants
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.
This change occurs when the photoperiod, or amount of light and dark that the plant receives, changes to 12 hours of light and 12 hours of dark. In outdoor gardens this change can happen naturally with the seasons or, in more controlled environments like indoor gardens, by human intervention using light timers.
Treating plants with a silver thiosulphate solution results in seeds that will produce feminized plants nearly 100% of the time, and Kannabia’s breeders have found this method to be the most effective way to maintain the stability of the seeds and future feminized plants.
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.

When you wonder what does feminised seeds mean, the key is in the sex!
We’ve already mentioned how feminized seeds are easier to grow than regular seeds. That might be enough for you to let your guard down, but don’t be so care-free. As with male photoperiod plants, growing feminized cannabis comes with specific challenges, too.
• Sativas grow taller, slimmer, and with thin, elongated leaves. These sun-loving plants usually do best in a hot climate. The flowering time is usually longer compared to indicas.
As mentioned, recent research suggests that the specific effects of cannabis are not just due to cannabinoids, but are likely also influenced by aromatic compounds known as terpenes. More research in this area is needed, but it would explain why some strains, despite having identical THC:CBD ratios, have different effects.
HOW TO GROW FEMINIZED SEEDS
But don’t fret! These concepts may seem intimidating, but they’re perfectly understandable once you get an explanation. While we want to explain everything at once, we’ll go one at a time, focusing on feminized seeds for today.
• Indicas grow short and bushy, with wide leaves. They’re often quite robust, and grow in many environments.
Outdoors, planting your feminized cannabis in an optimal climate and during the right season is pivotal. Why? Because sunlight hours change depending on the season, and your plants need a specific schedule to thrive. To satisfy this need, you will usually want to plant them in spring (when there’s no frost) and harvest in fall.
Where there are more distinct differences between the subspecies, however, is in their growth and morphology:
