Cannabis seeds from well-known genetics: Amnesia, OG Kush, Moby Dick, Critical Jack, Blueberry and Lemon Kush, plus autoflowering versions marked Auto such as Jack Herer Auto, Bruce Banner Auto, Gelato Auto and Gorilla Glue Auto. Each pack is named after its strain, so you can compare lineages side by side before choosing.
Before picking a genetic, the article indica vs sativa explains what those labels really tell you and where they fall short. Two strain profiles go further: the OG Kush strain, with its nose and family tree, and Amnesia Haze, one of the best-known haze lines. If you would rather see the finished flower than the seed, the CBD buds and the THCX flower range carry several of the same names, ready to open and smell, in weights from a small sample pack upwards.

Feminized cannabis seeds: genetic performance
Feminized cannabis seeds are the gold standard for collectors who want stability and high yield potential. Unlike regular seeds, which produce a 50/50 male/female ratio, feminized versions guarantee 99.9% female plants. For the expert collector, this ensures the preservation of genetics that produce dense flowers, rich in trichomes and complex terpene profiles.
Why buy feminized cannabis seeds?
✅ Optimisation of space and resources: Every seed is productive. You don’t waste resources on male plants that don’t produce the desired results.
✅ Stability of chemotypes: Feminised cannabis seeds ensure consistent cannabinoid levels. They allow you to maintain a stable phenotype with consistent concentrations across your entire genetic library.
✅ Organic depth: By focusing the plant’s energy on resin production, these seeds reveal the full aromatic potential of famous strains such as Kush, Haze, and Diesel.
✅ Photoperiod control: Unlike autoflowering seeds, feminized cannabis seeds are photoperiodic. They therefore offer total control over the vegetative growth phase, which allows the plant’s structure to be strengthened before flowering.
✅ High technical performance: Their genetic robustness is ideal for advanced growing methods such as SCROG, SOG, or Main-lining, which are essential for maximizing results in controlled environments.
Feminised seeds: who are they for?
Feminized cannabis seeds are the preferred choice of experts. They are intended for collectors who already have a good understanding of plant physiology and want to work on complex plant structures to achieve maximum flower density.
This is the safest investment to build you a first-rate genetic library. They give you the flexibility to manage iconic strains—such as OG Kush or Skunk—while eliminating the uncertainties of natural breeding. In short: you keep total control over the quality and lineage of your collection.
Autoflowering cannabis seeds: fast, simple, and discreet :
Unlike feminized seeds, autoflowering cannabis seeds incorporate a specific genetic trait called Cannabis Ruderalis, which originates from regions with harsh climates such as Siberia. This natural heritage allows them to trigger flowering based on their age rather than the amount of light exposure.
Why buy autoflowering cannabis seeds?
✅ Speed of development: These varieties can go from seed to mature plant in just 8 to 10 weeks. This is the optimal solution for quick results without depending on seasonal cycles.
✅ Internal biological clock: “Autos” do not require a change in light cycle (switching to 12 hours/12 hours) to produce flowers. They follow a fixed genetic calendar, often set to automatic flowering after a few weeks of growth.
✅ Genetic robustness: Thanks to their Ruderalis heritage, these seeds produce plants that are better able to withstand temperature variations and technical errors. They are particularly suited to cool climates or less stable environments.
✅ Discretion and compact size: With an average height of between 60 and 100 cm, these plants have a compact, stocky structure, making them suitable for small spaces or balconies.
✅ Multiple harvests: Outdoors, their short cycle allows for several sessions in a single season, where a classic plant would require several months of patience.
Who are autoflowering cannabis seeds intended for?
Autoflowering cannabis seeds are the ideal choice for beginners who don’t yet have a “green thumb” or for experts who want to achieve staggered harvests outdoors. By starting several cycles as soon as the frosts are over, it is technically possible to obtain 2 to 3 harvests in a single season.
To summarize: it is the “off-road” genetics par excellence. It offers you total peace of mind while guaranteeing modern and efficient aromatic profiles.
Legal disclaimer & safety of our premium cannabis seeds.
SPLIFF® sells all cannabis seeds strictly as collectible souvenirs and genetic preservation items.
- Germination and cultivation: across the 21 EU countries we ship to, germinating or cultivating cannabis seeds is prohibited, or permitted only under a specific national licence. Buying and holding seeds as a collectible is treated separately from growing them.
- Genetics: the potential shown on each product page (THC, aroma, cycle) describes the genetics of the strain, not the content of the seed: a seed contains no cannabinoids.
Your Responsibility: By purchasing, you certify that you are over 18 and are solely responsible for knowing and abiding by all local and national laws regarding the use and cultivation of cannabis seeds.
Enrich your collection with SPLIFF® premium cannabis seeds.
With SPLIFF®, you invest in stable genetics, certified quality and total peace of mind. Whether you opt for the quality of Autoflo or the performance of Feminized, you choose the elite seeds on your SPLIFF® shop.

Why buy feminized cannabis seeds for my collection?
Feminized seeds are the choice of the expert collector. They guarantee total genetic stability by preserving only the potential of the female profile, recognized for its aromatic complexity and its richness in terpenes.
- Genetic purity: Each seed captures the exact essence of the parent strain, offering the highest botanical study value.
- Maximum stability: Eliminates the unpredictability of male specimens for a homogeneous and valuable collection.
- Aromatic heritage: It is in these genetics that the greatest potential for olfactory diversity is concentrated.
How can I properly store my cannabis seeds to guarantee their germination potential?

Why choose SPLIFF® autoflowering cannabis seeds?
Good long-term preservation is essential to preserve viability (germination guarantee). Seeds should be stored in a cool, dark and dry environment.
- Refrigeration (4°C to 8°C) is ideal. Avoid freezing unless they are perfectly dried, but a cool cellar or cabinet works for shorter periods.
- Light can degrade genetic material. Keep your seeds in a container away from light in a dark place.
- Store in an airtight container away from moisture (low humidity is essential to prevent mold and early germination).
Is the intensity of the effects different between feminized and autoflowering strains?
The intensity of a strain (its potential for cannabinoids and terpenes) is determined by the specific genetics of the variety, not by the type of seed (feminized vs. autoflowering). Both SPLIFF collections offer lines selected for their high potential. As a collector’s item, feminized seeds historically offer the greatest potential for development, but our modern autoflowers are also chosen for their documented genetic richness and complex terpene profiles.
Can I grow SPLIFF® cannabis seeds at home?
SPLIFF® markets these seeds exclusively for collection and genetic study purposes. Germination and cultivation are governed by national law and are prohibited or strictly regulated in most EU member states. We are not responsible for any failure to comply with these laws.
Are cannabis seeds legal in the EU?
How is the genetic quality of SPLIFF® cannabis seeds guaranteed?
