female only marijuana seeds

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.

If you have more questions about strains or seeds, keep digging through Leafly’s resources.

Male vs. Female Cannabis Plants

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.

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.

As a rule of thumb, you cannot know what sex the Marijuana seeds are by just looking at them. Even Feminized Marijuana seeds are 99.99999% certain to be female. The only way you can find out what marijuana seeds are female is by germination. After two or three weeks, you will see the male or female flowers and this is the only way to know for sure what marijuana seeds are female.

Feminized marijuana seeds are the “easiest” seeds to grow after the Auto-flowering varieties. Feminized marijuana seeds mean that they are treated to make them female marijuana seeds (hence the name feminized) so that all the marijuana seeds can be used to get flowers. Breeders usually sell feminized marijuana seeds for their strains because they are easier to grow than regular female marijuana seeds and are too unstable to reproduce, although some people use female plants from feminized marijuana seeds to get cuttings, it is advisable that they use female from Regular marijuana seeds. It is recommendable to start growing with Feminized marijuana seeds, this will mean that the final plant won’t have any undesirable surprises like marijuana seeds reducing potency since there are only female marijuana plants.

Before you plant the first seed, you’ll need to make some decisions:

Breeders and growers developed feminized cannabis seeds to address these challenges. By increasing the likelihood that all your seeds will produce female plants, you eliminate the possibility of getting a male plant that won’t produce flowers and of having a male plant accidentally pollinate flower-bearing female plants.

Are regular seeds better than feminized?

Each of these areas may generate more questions. If you grow indoors will you use natural or artificial light? If you go hydroponic, will you also use a grow medium like rockwool or hydroton? While you could just buy a clone, plop it in some soil, and hope, it’s best to think like a beginner and do some thorough research before taking the marijuana-growing plunge.

Feminized seeds are bred to produce only female plants, as opposed to regular seeds that have a 50% chance of producing male plants.

Growing cannabis is all about your goals and preferences. There is no inherent reason why regular female marijuana seeds would be considered better than feminized seeds. With that said, feminized seeds:

Autoflowering seeds have been bred to move into the flowering phase without needing changes in light to activate the production of flowers. Whether cannabis seeds are seeds doesn’t have anything to do with when plants enter the flowering phase. Feminized cannabis seeds have been bred to grow only female plants.
