Autoflower Seeds

All seeds sold by Evertree are strictly sold as souvenirs and collectors’ items for genetic preservation purposes only. They are not sold for germination or cultivation. Cannabis seeds are a non-controlled part of the cannabis plant under the Misuse of Drugs Act 1971; however, cultivating cannabis plants without the appropriate Home Office licence is unlawful in the UK. Customers are responsible for complying with the law applicable in their location.

Autoflower cannabis seeds contain genetics developed around the autoflowering trait, traditionally associated with Cannabis ruderalis. Unlike photoperiod varieties, autoflower genetics are associated with flowering according to maturity rather than relying on a change in the light cycle.

Our autoflower cannabis seed collection includes genetics from Royal Queen Seeds, FastBuds, Sensi Seeds and Barney’s Farm, covering a wide range of indica, sativa and hybrid lineages. Individual varieties differ considerably in genetic background, cannabinoid profile, terpene characteristics and other breeder-described traits.

What Are Autoflower Cannabis Seeds?

Autoflower cannabis seeds are varieties bred with genetics that carry the autoflowering trait. This characteristic is historically associated with Cannabis ruderalis, which developed differently from traditional photoperiod cannabis lineages.

Modern breeders combine autoflowering genetics with selected indica, sativa and hybrid parent lines. This allows established strain genetics and newer crosses to be offered in autoflower form while retaining their own individual lineage, cannabinoid and terpene characteristics.

The term autoflower describes a genetic flowering characteristic. It does not describe one particular cannabinoid profile, strain type or breeder, so individual autoflower varieties can differ significantly from one another.

Autoflower vs Photoperiod Genetics

One of the main differences between autoflower and photoperiod cannabis genetics is how flowering is triggered.

Photoperiod varieties are genetically associated with changes in the hours of light and darkness before flowering begins. Autoflower varieties differ because their autoflowering heritage allows flowering to begin according to maturity rather than depending on a change in light cycle.

This distinction is separate from classifications such as indica, sativa, hybrid or feminized. An autoflower variety can contain indica, sativa or hybrid genetics, and many modern autoflower cannabis seeds are also feminized.

Autoflower Cannabis Seed Brands

Our autoflower collection brings together genetics from four established cannabis seed breeders.

FastBuds specialises heavily in autoflower cannabis genetics, with a large catalogue covering modern hybrids, established strain influences and newer breeding lines.

Royal Queen Seeds offers a broad autoflower range covering recognised cannabis genetics alongside newer varieties and its F1 hybrid collection.

Sensi Seeds combines its long-established cannabis breeding heritage with autoflower versions of recognised strains and newer hybrid genetics.

Barney’s Farm offers autoflower varieties based on a range of established strain lineages and modern hybrids with differing cannabinoid and flavour profiles.

Autoflower F1 Hybrid Seeds

The collection also includes autoflowering F1 hybrid cannabis seeds from Royal Queen Seeds. F1 refers to the first generation produced from carefully developed parent lines and is a breeding classification rather than a separate flowering type.

Current examples include Orion F1, Epsilon F1, Milky Way F1 and Titan F1. These combine autoflowering characteristics with the greater genetic uniformity associated with true F1 breeding.

Choosing Autoflower Cannabis Seeds

When comparing autoflower cannabis seeds, start with the breeder and genetic lineage. Autoflower is a broad category, and varieties can have very different indica, sativa and hybrid backgrounds.

Cannabinoid profile is another useful point of comparison. THC and CBD characteristics vary between individual strains, while CBD-focused autoflower genetics form a separate part of the wider autoflower collection.

Flavour and terpene characteristics also differ considerably between varieties, with breeder descriptions ranging from fruity and citrus profiles to earthy, herbal, sweet and more complex combinations.

Individual product pages provide the breeder, genetic background, cannabinoid profile and other available breeder specifications for each variety.

Autoflower Cannabis Seeds FAQ

What are autoflower cannabis seeds?

Autoflower cannabis seeds contain genetics associated with flowering according to maturity rather than relying on a change in the light cycle.

Modern autoflower varieties generally combine this characteristic with selected indica, sativa or hybrid cannabis genetics.

What is the difference between autoflower and photoperiod seeds?

The main difference is the genetic flowering characteristic. Photoperiod varieties are associated with changes in hours of light and darkness, while autoflower varieties begin flowering according to maturity.

Both categories can include a wide range of indica, sativa and hybrid genetic backgrounds.

Are autoflower cannabis seeds feminized?

Many modern autoflower cannabis seeds are feminized, but autoflower and feminized describe different genetic characteristics.

Autoflower refers to the flowering trait, while feminized refers to seeds bred to greatly reduce the likelihood of male plant genetics appearing. A seed can therefore be both autoflowering and feminized.

Do autoflower seeds contain ruderalis genetics?

The autoflowering trait is historically associated with Cannabis ruderalis. Breeders have used autoflowering genetic lines alongside selected indica, sativa and hybrid genetics to develop the modern autoflower varieties available today.

Are F1 hybrid seeds the same as autoflower seeds?

No. F1 describes the breeding generation, while autoflower describes a flowering characteristic. An F1 hybrid can be autoflowering or photoperiod depending on its genetics.

The Royal Queen Seeds F1 hybrids currently included in Evertree’s autoflower collection are autoflowering varieties.

Are cannabis seeds legal in the UK?

Cannabis seeds themselves are a non-controlled part of the cannabis plant under UK law. However, cultivating cannabis plants without the appropriate Home Office licence is unlawful.

All cannabis seeds sold by Evertree UK are sold strictly as souvenirs and collectors’ items and are not sold for germination or cultivation.
