What are feminised seeds?
Feminised cannabis seeds are genetically designed to produce nearly 100% female plants. This eliminates the need to identify and remove males during cultivation, saving time, space and resources.
This type of seed is obtained through controlled processes that induce the production of female pollen (XX), guaranteeing stable and productive offspring. Nowadays, most professional seed banks work primarily with feminised seed, due to its reliability and performance.
Thanks to this, the grower can focus on optimising growth, flowering and the final quality of the buds.
Advantages of feminised seeds
Choosing feminised cannabis seeds offers clear advantages over regular seeds:
- Up to 99% guarantee of female plants
- Higher and more consistent production
- Larger, more vigorous and stable plants
- Better use of growing space
- Wide variety of THC, CBD, aroma and flavour profiles
- Ideal for both indoor and outdoor cultivation
That's why they remain the preferred choice for both beginners and advanced growers.

What's better, autoflowering or feminised seeds?
It depends on your growing goals:
- Feminised seeds → More production, better quality, total photoperiod control
- Autoflowering → Faster, easier and more compact
If you're after maximum yield, large buds and classic genetics, feminised cannabis remains the best choice.
How to grow feminised seeds? Indoor and outdoor
Indoors it's best to control temperature (22–26°C), humidity and light cycles. Outdoors, planting in spring ensures maximum vegetative development.
Basic tips:
- Germinate properly
- Use larger final pots
- Control light stress
- Apply progressive nutrition
- Maintain good ventilation
With these points you'll get healthy and productive plants.

Preguntas frecuentes de Feminised Seeds
How long does a feminised seed take to grow?
The total time it takes for a feminised seed to grow until harvest varies depending on genetics and growing conditions. Generally, the complete cycle can last between 3 and 5 months. After germinating in just a few days, the plant goes through the vegetative phase (which lasts between 4 to 8 weeks) and then the flowering phase, which can last between 6 to 10 weeks, depending on genetics and growing environment.
How do you tell if your seed is male or female?
Feminised seeds are designed to produce only female plants, but if you grow regular seeds, you'll need to wait until the advanced vegetative phase or pre-flowering to identify the plant's sex. Male plants produce pollen sacs (resembling small balls), whilst female plants develop pistils (fine white hairs). Using feminised seeds eliminates uncertainty and ensures the plant will be female at 99%.
How do you make a male plant female?
It is not possible to convert a male plant into a female plant. Male plants produce pollen and not flowers, so they don't have the same value for those seeking to harvest buds. To ensure you have female plants, it is recommended to use feminised seeds, which are specifically designed to prevent the appearance of male plants.
How long does a feminised plant take to produce fruit?
A feminised plant takes between 6 to 10 weeks from the start of the flowering phase to produce fruit (buds). The exact duration depends on the variety, light conditions, and type of cultivation (indoor or outdoor). After the vegetative phase, flowering begins, and in the space of 1-3 months you'll be able to harvest.
How many litres of soil does a feminised plant need?
The size of the pot influences the size and health of the plant. To grow a feminised plant, it is recommended to use pots of between 3 and 20 litres of soil if growing indoors. Outdoors, where plants can grow larger, you can use larger pots of up to 80 litres or even plant directly in the soil.
When should I plant feminised seeds?
The best time to plant feminised seeds outdoors is in spring, when temperatures begin to warm up and daylight hours increase. In the northern hemisphere, this is usually between March and June. If you grow indoors, you can plant at any time of year, as you can control the light cycle and environmental conditions.
When should I put seeds in the sun?
Germinated seeds should be exposed to sun or artificial light as soon as they sprout and emerge as seedlings. In outdoor crops, it is ideal to place them in the sun in spring, when temperatures are mild and daylight hours are longer. Avoid direct exposure to very intense sun in the first few days, as seedlings are delicate.
How many hours of light does a feminised seed need?
During the vegetative phase, feminised seeds need between 18 and 20 hours of light per day for optimal growth. Once the plant enters the flowering phase, the light should be reduced to 12 hours per day to mimic natural cycles and stimulate bud production.
What happens if I give the plant 24 hours of light?
Giving a feminised marijuana plant 24 hours of light during the vegetative phase can accelerate its growth, but it is not recommended long-term, as plants also need a period of darkness to perform important biological functions. A light cycle of 18-20 hours is usually most effective for healthy growth.
Which is better, feminised or autoflowering seeds?
Feminised seeds are ideal for growers seeking plants of authentic genetics without crossing with ruderalis and that allow you to control the light cycle and usually produce higher quality and larger flowers. On the other hand, autoflowering seeds are easier to grow, as they flower automatically without the need for light cycle changes, making them ideal for beginners or quick crops. The choice depends on your level of experience and cultivation objectives.
Which is better, a feminised or regular seed?
Feminised seeds are better if your goal is to produce flowers (buds), as almost 100% of the plants will be female. Regular seeds, which can produce both male and female plants, are more suitable for those who want to create new genetics or produce their own seeds. Feminised seeds offer a simpler option and guarantee a higher yield of flowers.
What happens if you're caught with cannabis seeds?
In Spain, possession of seeds is not an offence. Cultivation must take place in private and not visible from public roads.
How long does a feminised cannabis seed take to germinate?
Typically between 24 and 72 hours, depending on temperature and method.
How many cannabis plants can I legally have in Spain in 2025?
There is no specific legal number. Private cultivation is required, with no intent to traffic and not visible publicly.
What's the difference between feminised and autoflowering seeds?
Feminised varieties depend on photoperiod and produce larger plants. Autoflowering ones flower on their own and are faster.
How many hours of light does a feminised seed need?
18–20 hours during growth and 12 hours during flowering.
How long does a feminised plant take to produce buds?
Between 8 and 10 weeks of flowering, depending on genetics.
