Feminised cannabis seeds are bred to produce only female plants. They first appeared in the 1990s and quickly became the go-to choice for collectors everywhere.
Today you'll find feminised versions of indica, sativa, and hybrid strains, with most modern varieties blending traits from different types.
Feminised seeds come from a clever breeding trick. Breeders treat a female plant so it makes pollen that only carries female chromosomes. When that pollen fertilises another female, the seeds have no male genetics at all.
The usual method involves spraying with colloidal silver or silver thiosulfate, which flips the switch and makes the plant produce pollen even though it's female.
The result? Seeds with about a 99.9% chance of becoming female plants.
Dutch Passion were the first to crack this back in the day, creating feminised seeds that delivered 95% or more females and completely changing the game.
Barney's Farm also jumped in early, refining the process over nearly forty years.
By the late 1990s, feminised seeds had gone from a cool experiment to the number one pick for collectors worldwide, and they've stayed on top ever since.
What's out there
You'll find feminised seeds across all the main cannabis types: indica, sativa, hybrids, and even ruderalis. Indica-leaning strains tend to be shorter and bushier with wide leaves, while sativa types stretch taller with longer branches and thinner leaves.
Most modern feminised strains are hybrids, mixing indica and sativa to balance things out. Take Amnesia Kush, for instance, it's 70% sativa and 30% indica with THC around 15–20%.
Big Kush sits right in the middle at 50/50 with THC between 17 and 22%, and Bubba Kush leans heavily indica at 90/10 with THC around 16–20%.
Thousands of feminised strains are now on the market from top seed banks like Royal Queen Seeds, Barney's Farm, Sensi Seeds, and Dutch Passion.
Collectors can pick from classic Californian genetics, cutting-edge hybrids, fast-flowering varieties that finish in 60 to 70 days, and strains bred for strong aromas and high potency.
Feminised seeds come in both photoperiod and autoflowering formats. Photoperiod types need a shift in light hours to start flowering, while autoflowers bloom based on age no matter what the light's doing.

Breeders treat a female plant so it produces pollen with only female chromosomes. That pollen fertilises another female, and the seeds have no male genetics. Common treatments include colloidal silver and silver thiosulfate.
Feminised seeds have about a 99.9% success rate. Early Dutch Passion tests found nine out of fifteen feminised varieties gave 100% females, with the rest hitting 80 to 90%.
Yes, feminised seeds are available across all the main cannabis types: indica, sativa, hybrids, and ruderalis. Most modern feminised strains are hybrids, though pure indica and sativa are also around.
Feminised seeds usually cost a bit more because of the additional work required for the breeding process.
