What Is Cannabis?

Cannabis is known by many names, including weed, grass and ganja. It is a genus of flowering plants that includes varieties commonly classified as Cannabis sativa, Cannabis indica and Cannabis ruderalis. Mature cannabis plants contain numerous naturally occurring compounds, including cannabinoids, terpenes and flavonoids.

More than 100 cannabinoids have been identified in cannabis, with THC and CBD being the two most widely recognised. The genetics carried by a cannabis seed can influence characteristics such as plant structure, flowering time, aroma, flavour and potential cannabinoid profile.

Like other plants, cannabis begins in seed form. However, the characteristics expressed by a mature plant depend on a combination of genetics and environmental conditions. This makes the breeder, parent lineage and genetic stability important considerations when comparing cannabis seeds.

What Are Cannabis Seeds?

Cannabis seeds carry genetic information inherited from their parent plants. When a seed develops, it can express different combinations of characteristics from each parent, which is why individual plants from the same strain may display some natural variation.

Plants can also be propagated through cuttings, commonly known as clones. A clone is a genetic copy of its parent plant, while a seed contains a new combination of inherited genetics. Neither method is automatically superior, as the quality and stability of the resulting plant depend on the original genetics and environmental conditions.

Regular cannabis seeds can produce male or female plants. Male plants produce pollen, while female plants produce the resinous flowers commonly associated with cannabis. Feminised and autoflowering seeds offer different characteristics, which we explain below.

Types of Cannabis Seeds

There are three main types of cannabis seed: regular, feminised and autoflowering. Each has different characteristics and may appeal to growers and collectors for different reasons.

Some growers value the traditional genetic diversity of regular seeds, while others prefer the predictability of feminised seeds or the shorter life cycles associated with autoflowering cannabis seeds. Understanding the differences can help you choose the most suitable genetics for your preferences.

Regular Cannabis Seeds

Regular cannabis seeds are produced through traditional breeding between male and female parent plants. Each seed generally has a roughly equal chance of producing a male or female plant.

Regular seeds remain popular with breeders because they preserve both male and female genetic potential. This makes them valuable for creating new crosses, preserving traditional lineages and selecting desirable parent plants.

Potential advantages of regular cannabis seeds include:

• Male and female genetic potential
• Greater suitability for traditional breeding projects
• Access to heritage and specialist genetics
• Wide availability across established strains
• Greater genetic diversity within some seed lines
• The ability to select male plants for breeding

Regular seeds require growers to identify male and female plants if unpollinated flowers are the aim. However, they remain an important choice for experienced growers, breeders and collectors interested in traditional cannabis genetics.

Feminised Cannabis Seeds

Feminised cannabis seeds are selectively bred to have a very high likelihood of producing female plants. This reduces the need to identify and remove males and allows growers to make more efficient use of their available space.

Feminised varieties are available across a huge range of established strains, modern hybrids and breeder collections. They have become one of the most widely chosen cannabis seed types because of their predictability and convenience.

Potential advantages of feminised seeds include:

• A high likelihood of female plants
• More efficient use of available space
• Less time spent identifying and removing males
• A broad choice of strains and breeders
• Availability in both photoperiod and autoflowering varieties
• Greater predictability when planning a crop

Feminised seeds are not guaranteed to produce identical plants or a particular result every time. Genetic expression can still vary, and final plant quality depends on the breeder, strain and surrounding environment.

Autoflowering Cannabis Seeds

Autoflowering cannabis seeds contain genetics associated with Cannabis ruderalis. Unlike traditional photoperiod varieties, which begin flowering in response to longer periods of darkness, autoflowers start flowering primarily according to age.

This characteristic makes them popular with growers looking for shorter life cycles and a simpler flowering process. Modern autoflowering seeds are available across classic strains, new hybrids and THC-dominant, CBD-rich and balanced cannabinoid profiles.

Potential advantages of autoflowering cannabis seeds include:

• No need to trigger flowering by changing the light cycle
• Comparatively short life cycles
• Compact structures in many varieties
• A wide choice of feminised options
• Autoflowering versions of established strains
• Greater flexibility around seasonal light changes

Autoflowers still require appropriate light, moisture, nutrients and environmental conditions. Their shorter life cycle can make them convenient, but it may also leave less time for recovery if problems occur during early development.

What Are Cannabis Strains?

You wouldn’t walk into a wine shop and assume every bottle was the same, and cannabis strains are no different. Each strain carries a particular genetic background that can influence its structure, aroma, flavour, flowering time and potential cannabinoid profile.

A cannabis strain is a named genetic variety created through natural variation or selective breeding. Breeders cross parent plants with desirable characteristics and stabilise the resulting genetics over multiple generations.

Well-known strains such as White Widow and Northern Lights have also been used as parent genetics in countless newer hybrids. As breeders continue creating and refining new crosses, the number of commercially available cannabis strains continues to grow.

Different Types of Cannabis Strains

Cannabis strains are commonly described as Indica, Sativa or Hybrid. These labels traditionally refer to genetic ancestry and certain physical characteristics, although they are also frequently used to describe reported effects.

Indica varieties are often associated with shorter, broader-leaf plants, while Sativa varieties are commonly associated with taller plants and narrower leaves. Hybrids combine genetics from different cannabis varieties and may be described as Indica-dominant, Sativa-dominant or balanced.

These classifications do not reliably predict exactly how a particular strain will affect an individual. Reported effects can also be influenced by cannabinoid content, terpene profile, dosage, tolerance and personal biology.

Indica

Indica strains are traditionally associated with shorter plants, broader leaves and comparatively compact structures. They are often described as producing relaxing or physically calming effects, although individual experiences can vary considerably.

When comparing Indica cannabis seeds, consider:

• The breeder and parent genetics
• Expected flowering period
• Reported plant height and structure
• THC and CBD estimates
• Aroma and terpene profile
• Whether the seeds are regular, feminised or autoflowering

Sativa

Sativa strains are traditionally associated with taller plants, narrower leaves and longer flowering periods. They are often described as producing uplifting, energising or cerebral effects, although these descriptions should not be treated as guarantees.

When comparing Sativa cannabis seeds, consider:

• The strain’s genetic lineage
• Expected flowering time
• Reported height and stretch
• Cannabinoid profile
• Aroma and terpene characteristics
• Whether the variety is pure Sativa or Sativa-dominant

Hybrid

Hybrid strains combine genetics from different cannabis varieties. Some are bred to bring together the structure, flowering time, aroma or cannabinoid characteristics of selected Indica and Sativa parent plants.

A hybrid may lean strongly towards one side of its lineage or offer a more balanced combination of characteristics. The result depends on the parent genetics and the breeding work carried out to stabilise the strain.

When comparing hybrid cannabis seeds, consider:

• The parent strains used in the cross
• Whether the hybrid is Indica- or Sativa-dominant
• Expected flowering period
• Plant structure and reported height
• Cannabinoid and terpene profile
• The breeder’s reputation and strain information

Choosing Your Strain

Once you understand the main strain classifications, you can begin narrowing down the cannabis seeds that best match your interests and preferences.

Important factors to consider include:

• Whether the strain is Indica, Sativa or Hybrid
• The breeder and parent genetics
• Whether the seeds are regular, feminised or autoflowering
• Expected flowering time and plant structure
• Breeder-reported THC and CBD levels
• Aroma, flavour and terpene profile
• Available pack sizes and price
• Independent customer feedback and breeder information

Established strains often have more widely available information, reviews and grow reports, while newer or rarer genetics may appeal to collectors looking for limited releases and unusual crosses.

Strains carrying the same name can also vary between breeders. Always review the parent lineage and breeder information rather than relying on the strain name alone.

CBD vs THC

CBD, or cannabidiol, and THC, or tetrahydrocannabinol, are two of the best-known cannabinoids found in mature cannabis plants. Breeders frequently include estimated CBD and THC percentages in their strain descriptions.

THC is the principal intoxicating cannabinoid associated with cannabis. CBD is generally considered non-intoxicating and does not produce the same type of high.

Cannabis strains can be described as:

• THC-dominant
• CBD-rich
• Balanced in THC and CBD
• Low in both principal cannabinoids

The cannabinoid profile is determined primarily by the strain’s genetics rather than by whether the seed is regular, feminised or autoflowering. Any percentages supplied by a breeder are estimates, and actual levels can vary according to environmental conditions.

Cannabinoid information is provided for strain comparison and should not be interpreted as medical advice or a guaranteed description of effects.
