Buy cannabis seeds — Feminized, autoflowering, and CBD at Edabea

At Edabea, you will find a selection of cannabis seeds from specialized European breeders, organized into three categories based on flowering type and cannabinoid profile: feminized, autoflowering, and CBD seeds. The catalog includes genetics from Barney's Farm, Green House Seeds, Sweet Seeds, Sensi Seeds, Dinafem, Paradise Seeds, Eva Seeds, Positronics, Cannabiogen, and Serious Seeds, among others. The choice between categories depends primarily on the available growing system, photoperiod control, and desired cannabinoid profile.

Technical differences between feminized, autoflowering, and CBD seeds

Feminized seeds

Feminized cannabis seeds are genetically modified to produce female plants in nearly 100% of cases. Female plants produce flowers — buds — with resin; male plants produce pollen, and if they pollinate females, drastically reduce resin production. Feminization eliminates the need to identify and remove male plants during cultivation.

The main characteristic is the dependence on photoperiod: cannabis Cannabis sativa L. is a short-day plant that begins flowering when the photoperiod is reduced below a certain threshold — indoors, transitioning from 18 hours of light (vegetative phase) to 12 hours (flowering phase). Outdoors, flowering begins naturally as the days shorten at the end of summer.

Autoflowering seeds

Autoflowering seeds incorporate genetics from Cannabis ruderalis, a subspecies from regions with short summers (Eastern Europe, Central Asia) that developed the ability to flower by age rather than photoperiod. An autoflowering plant starts flowering approximately 30 days after germination, regardless of the available light hours, and completes its full cycle — germination, vegetative growth, and flowering — in 10 to 11 weeks.

The main advantage of autoflowering seeds is their independence from photoperiod, which simplifies outdoor growing (multiple harvests per season, no need to control light) and indoor cultivation (lower energy consumption as light cycle changes are not required). Historically, the trade-off was lower yield and potency compared to photoperiodic feminized seeds, although modern third-generation varieties have significantly reduced these differences.

CBD seeds

CBD seeds are specifically selected or crossed to present a modified THC/CBD ratio compared to standard varieties. Cannabidiol (CBD) is a non-psychoactive cannabinoid that has generated increasing interest in clinical research in recent years. The CBD seeds in the catalog present different ratios depending on the variety: some with high CBD and THC <1% (non-psychoactive profile), and others with a 1:1 THC/CBD ratio. They can be feminized or autoflowering depending on the base genetics of each variety.

How to choose between feminized and autoflowering seeds

The primary decision is the photoperiod control available in the growing system:

Photoperiodic feminized: suitable for indoor cultivation with complete light control or outdoors in regions with a well-defined natural photoperiod. They allow for greater control of plant size during the vegetative phase and typically offer higher yield per plant under optimal conditions. They require a light cycle change to induce flowering indoors.

Autoflowering: suitable for outdoor cultivation without light control, terraces, or spaces where photoperiod manipulation is not feasible. They allow for multiple harvests per season outdoors and simplify indoor growing as no cycle changes are required. The complete cycle in 10–11 weeks from germination facilitates planning of cultivation.

Germination and preservation

Germination: under optimal temperature conditions (22–26°C) and relative humidity (90%), the radicle emerges in 2–7 days. Most varieties germinate within this range; some may take up to 10 days. The most common method is germination on damp kitchen paper between two plates, kept in darkness and stable temperature.

Preservation: cannabis seeds maintain their viability for several years if stored correctly. Optimal conditions are a temperature of 4–8°C (vegetable zone of the no-frost refrigerator), relative humidity of 10–20%, and complete darkness. Using silica gel in the airtight container helps maintain controlled moisture. Avoid freezing, abrupt temperature changes, and exposure to light.

Legal situation

The sale of cannabis seeds as a collection item is legal in many European countries, although germination and cultivation are subject to the regulations of each jurisdiction. It is the buyer's responsibility to verify the applicable legislation in their place of residence before germinating or cultivating. The seeds are sold exclusively as collection material.

Frequently asked questions about cannabis seeds

What is the difference between feminized and autoflowering seeds?

The main difference is the flowering mechanism. Feminized seeds are photoperiodic — they initiate flowering when the photoperiod is reduced below a certain threshold (12 hours of light indoors), which requires light control. Autoflowering seeds incorporate genetics from Cannabis ruderalis and flower by age — approximately 30 days after germination — regardless of the photoperiod. This simplifies cultivation but has historically led to lower yields, a difference that modern third-generation varieties have significantly reduced.

What are CBD seeds and how do they differ from standard ones?

CBD seeds are varieties selected or crossed to present a higher ratio of cannabidiol (CBD) compared to THC. CBD is a non-psychoactive cannabinoid. The CBD seeds in the Edabea catalog include varieties with THC <1% and high CBD (non-psychoactive profile), and varieties with a 1:1 THC/CBD ratio. They can be feminized photoperiodic or autoflowering depending on the base genetics of each variety.

When should cannabis seeds be planted outdoors?

For photoperiodic varieties outdoors, the optimum germination time is from March to May in the northern hemisphere, when minimum temperatures exceed 10°C, to make the most of the long vegetative phase before the natural photoperiod induces flowering in late summer. For autoflowering varieties outdoors, the optimal range is from May to June, when temperatures are stable and sunlight hours are sufficient to maximize growth. Indoors, cultivation is possible at any time of the year with light control.

How long do cannabis seeds take to germinate?

Under optimal conditions — temperature of 22–26°C and relative humidity of 90% — the radicle emerges in 2–7 days. Some varieties may take up to 10 days. If they have not emerged after 10–14 days, the seed's viability is low. Previous storage conditions (temperature, humidity, light) are the most influential factors on germination rate.

How to properly preserve cannabis seeds?

The optimal preservation conditions are a temperature of 4–8°C (the vegetable zone of a no-frost refrigerator), relative humidity of 10–20%, and complete darkness. It is recommended to store them in an opaque airtight container with silica gel to control moisture. Avoid freezing, abrupt temperature changes, and direct light exposure. When well preserved, seeds can maintain their viability for several years.
