Different types of cannabis seeds

There are different types of cannabis seeds available to the cannabis grower: regular, feminized and auto-flower. The following is a brief explanation of each type so you can determine what is best for your garden.

Regular Seeds

Regular seeds are produced by crossing a male plant with a female plant and can come in either male or female.

With regular seeds, the ratio of male-to-female plants is unknown until flowering starts and the plants present their sex. While female plants produce the desired flower, regular seeds offer growers the opportunity to experience the full expression of that strain’s genetic lineage.

Feminized Seeds

Feminized seeds grow into female plants that produce the desired flower or bud.

Feminized seeds are produced when a female plant produces male flowers. This is caused by introducing light at set times during the dark hours of flowering, or by spraying the flower sites of a female plant with Colloidal Silver to produce a chemical change in the plant that produces male flowers with pollen.

Pollen from “male” flowers are used to pollinate other female flowers, and because the pollen from the “male” flowers is originally from a plant that is technically female, all of the offspring produced should be female.

Auto-Flower Seeds

If you are new to growing cannabis, auto-flower seeds may be right for you. Plants will flower when they reach a certain maturity, usually ten weeks from seed, as opposed to flowering in accordance with the daily light schedules.

Auto-flower strains are crosses of modern day strains with Cannabis Ruderalis strains. Cannabis Ruderalis is the 3rd subtype of cannabis, the other two being Indica and Sativa. Cannabis Ruderalis is typically found closer to the North and South Pole, and have a very different lifespan compared to strains originating closer to the Equator.

Due to the lack of sunlight for extended periods of time at both the North and South Pole, Cannabis Ruderalis strains have developed to the point where no matter how much light is present, they will finish out their life cycle.

Dissecting the 3 Types of Cannabis Seeds: Regular, Feminized, and Autoflowering

When deciding to grow cannabis, the first place to start is with the seeds. Most seed banks will give you the option to choose the type of seed you want for each strain. Cannabis seeds are divided into three distinct categories: regular, feminized, and auto-flowering. The kind of seed you choose ultimately depends on your experience growing cannabis, and how well you understand the process. Each seed-type comes with its own benefits and drawbacks.

Let’s break down the three types of cannabis seeds to help you get to know the pros and cons of each.

Regular seeds

Regular seeds are the result of sexual reproduction between a male (pollen-producing) plant and a female (ovule bearing) plant. In Cannabis cultivation, these seeds are usually the product of hand-pollination. A breeder hand-pollinates a female plant using pollen collected from a male plant. The seeds produced by these hand-pollinations are similar to the seeds produced by wild populations of cannabis.

Advantages of regular seeds

They are relatively inexpensive and easy to find. Many expert growers suggest that beginners use regular seeds for their first few cultivation attempts. Beginners are more likely to make mistakes, and regular seeds are inexpensive and easy to replace. Regular seeds are also popular among plant breeders, who need both male and female plants to experiment with selective breeding. Regular seeds are also available in a variety of strain combinations, such as indica-dominant or sativa-dominant.

Disadvantages of regular seeds

There is a 50% chance the seed produces a male plant. It can be hard to differentiate male plants from female plants until they are at least 3-4 week old seedlings. You could end up with male plants in a greenhouse full of females. Male plants are usually undesirable unless you are trying to breed new strains or collect pollen for future use (“pollen banking”).

Feminized seeds

When female Cannabis plants are “stressed” they sometimes begin to produce pollen. Stressful conditions for a female Cannabis plant include inadequate water, intense heat/UV light, intense herbivory, or insufficient access to male plants. Growers have learned to take advantage of this natural phenomenon to produce “feminized seeds.” If a female Cannabis plant is subjected to stressful conditions (or chemicals are applied to the plant to mimic stressful conditions), the female plant may produce pollen-bearing flowers. Pollen is harvested from those flowers and used to pollinate the female flowers of the same plant (self-pollination). Once the female plant has pollinated itself, it is almost guaranteed to produce seeds that will only grow up to be females (due to the lack of Y chromosomes involved in reproduction).

Advantages of feminized seeds

While reliable empirical evidence is lacking, some growers report that >98% of feminized seeds produce female plants. If your primary goal is to produce seedless female buds and you do not want to worry about accidentally growing male plants, this may be the best option for you.

Disadvantages of feminized seeds

Feminized seeds are more expensive than regular seeds. They would not be suitable for anyone hoping to collect pollen or breed new strains.

Autoflowering seeds

The most popular varieties of Cannabis are Cannabis ssp. sativa and Cannabis ssp. indica. However, there is a third subspecies of Cannabis, C. ruderalis. Ruderalis evolved to survive and reproduce in the long-winter climates of Europe and Russia. Spring and summer are very short in these regions, so ruderalis developed fewer light requirements to trigger seed germination and flowering. Seeds that contain ruderalis genetics do not require a change in light cycle to germinate or begin flowering, so they are described as “auto-flowering”.

Advantages of autoflowering seeds

These seeds produce small plants that flower very quickly, which may be an advantage if you do not have a lot of time or growing space. The short stature of these plants may also be an advantage if you are trying to grow plants under a legal height limit. You also do not need an elaborate cultivation plan or lighting system. Plants grown from auto-flowering seeds often produce flowers that are high in CBD but low in THC, making them a good option for medicinal cannabis users.

Disadvantages of autoflowering seeds

The plants produced by autoflowering seeds are often characterized by flowers with very low THC content. These seeds produce small plants, so they may not be a good option if you are trying to produce large quantities of buds.

Whichever type of seeds you choose, you can still grow high-quality cannabis plants. Some seeds involve more hands-on care than others, but depending on how much work you want to invest in the process, all of the cannabis seeds we mentioned can get you bountiful yields. When choosing a seed type, keep in mind things like your grow space, your budget, and how much time you’re willing to invest in the grow.
