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.

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.

Why Grow From Feminized Cannabis Seeds?

There are numerous advantages for growers who start their garden using feminized seeds. By removing the guesswork of germinating regular seeds, feminized seeds streamline the growing process, saving space and time.

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.

Also known as ‘cloning by seed,’ it is a reliable way to avoid producing male plants. On the downside, finding a stable mother plant for seed production is expensive and time-consuming.

A high percentage of feminized seeds become hermaphrodites. This scenario results in marijuana flowers with seeds in them and lower overall yield. Don’t use feminized seeds if you intend to breed plants. On the plus side, this type of seed is ideal for beginners who want to avoid male plants infiltrating their cannabis garden.

What Are Feminized Marijuana Seeds?

A cannabis clone is a cutting taken from a marijuana plant. You place it in a growing medium (such as soil or Rockwool) to ensure it grows roots. After the cutting has rooted, you can guide it into a mature plant. Best of all, it is genetically identical to the plant you cut it from.

Waste not, want not!…

Autoflowering cannabis seeds are very different. They are based on the Cannabis ruderalis species. It flowers once the marijuana plant reaches a certain age, regardless of its light exposure. It is possible to cross a potent marijuana strain with a lower-THC ruderalis variety to produce an autoflowering strain.

Aside from producing cannabis through seeds, or sexual reproduction, you can also reproduce the plant through cloning, or asexual reproduction. A clone is a cutting that is genetically identical to the plant it was taken from—that plant is known as the “mother.”

There are a few indicators that will give you a sense of whether the seed is worth germinating.

What are feminized cannabis seeds?

For the typical homegrower, it may be easier to obtain cannabis seeds rather than clones. Growing from seed can produce a stronger plant with more solid genetics.

One way to avoid sexing plants is to buy feminized seeds (more below), which ensures every seed you plant will be a bud-producing female.

Cannabis is grown from one of two sources: a seed or a clone. Seeds carry genetic information from two parent plants and can express many different combinations of traits: some from the mother, some from the father, and some traits from both.
