Pre-flowering is one of the most exciting phases in the life of a cannabis plant, as it determines the success of the subsequent harvest. In our article, we take you through this important stage and explain how to recognise pre-flowering, what you need to pay attention to and how to optimally care for your plants.
You will learn which signs indicate pre-flowering and how to recognise the difference between male and female plants. This is crucial, as only female plants produce the coveted Flowers. We also give you practical tips on care, the right fertiliser and watering during this phase to ensure your plants grow healthy and strong. If you're growing outdoors, we'll explain what you need to consider in terms of weather, light conditions and the natural environment to successfully master pre-flowering.
Finally, we have summarised the most important facts once again so that you are well prepared to guide your plants through the pre-flowering phase into the decisive flowering phase.
Pre-flowering in cannabis: what does it mean?
The Cannabis pre-flowering is a crucial stage in the plant's life cycle. It begins when the plant completes its vegetative growth and prepares for Flower. During this phase, the plant shows signs of being male or female for the first time. Pre-flowering can be seen as a kind of "puberty" of the cannabis plant - the plant switches from pure growth to its reproductive phase.
In pre-flowering, the plant begins to invest more energy in the development of flower buds (in female plants) or pollen sacs (in male plants). At the same time, their nutrient requirements change. A particular advantage of this phase is that experienced growers can now recognise the sex of the plant and intervene at an early stage to remove unwanted male plants.
Pre-flowering is therefore the starting signal for a successful flowering phase and plays an important role in the later harvest quality.
Recognising pre-flowering: What does it look like in cannabis?
The Pre-flowering in cannabis is crucial for every grower, as it marks the transition to the flowering phase. But how exactly do you recognise this phase? The first signs of pre-flowering appear in the form of small outgrowths on the nodes (the places where the branches grow out of the main stem). In female plants, tiny, hair-like structures called stigmas form here. Male plants, on the other hand, develop small round balls - the precursors of the pollen sacs.
In order to Pre-flowering in cannabis To correctly recognise the first white hairs, you should inspect the plant regularly. In female plants, the first white hairs are a sure sign that the plant is entering the flowering phase. In male plants, on the other hand, small, smooth balls appear, which later mature into pollen sacs.
Another indicator of pre-flowering is the change in the plant's growth habit. It becomes bushier and more vigorous during this phase as it prepares for the upcoming Flower. Correct identification of pre-flowering helps to adapt further care steps and promote optimum development.
Distinguishing between male and female pre-flowering in cannabis
In the Pre-flowering in cannabis reveals for the first time whether a plant is male or female - a crucial piece of information, as only female plants produce the coveted Flowers. But how can you Cannabis male pre-flowering and Cannabis female pre-flowering reliably?
- Female pre-flowering: Female plants develop small "calyxes" on the nodes, from which fine, white hairs (stigmas) grow. These hairs are the first clear sign that the plant is female. The stigmas later serve to trap pollen and will continue to develop during the flowering phase and grow into the familiar cannabis flowers.
- Male pre-flowering: Male cannabis plants form small, round balls in the same places - the so-called pollen sacs. These balls are smooth and resemble tiny buds. During pre-flowering, these are still closed and only grow in the later flowering phase to release the pollen.
The early recognition of the male pre-flowering is particularly important to avoid unwanted pollination of the female plants. Male plants should be removed from the cultivation area as early as possible so that the female plants can concentrate their energy on flower formation.
The correct differentiation of male and female plants during pre-flowering is the key to a successful harvest and guarantees that the female plants are fully focussed on the production of high-quality Flowers.

How long does pre-flowering last in cannabis?
The Cannabis pre-flowering duration varies depending on the variety and growing conditions, but usually extends over one to two weeks. During this time, the plant adapts to the upcoming flowering phase and shows the first signs of its sex. With some varieties, pre-flowering can take a little longer, especially if they are grown outdoors or under natural light conditions.
Some factors that influence the duration of pre-flowering are:
- Variety (Strain): Indica-dominant plants often tend to switch to the flowering phase more quickly than sativa-dominant varieties.
- Lichtzyklus: Indoor growers can influence pre-flowering by changing the light cycle (e.g. to 12 hours of light and 12 hours of darkness) and thus accelerate the start of the flowering phase.
- Health of the plant: Healthy, well-maintained plants generally enter pre-flowering faster and more smoothly.
Patience is required during pre-flowering. The plant is now preparing to move into the decisive flowering phase and the grower should use this time to determine the sex of the plants and adapt the care measures accordingly.
Care during pre-flowering: What needs to be considered?
Pre-flowering is a critical phase where proper care lays the foundation for a successful Flower. During this time, the plant's nutritional requirements change and growers should pay attention to some essential points to support growth, especially the right Fertilising cannabis pre-flowering .
Tips for care during pre-flowering:
- Nutrient supply: During pre-flowering, the plant needs more phosphorus and potassium to prepare for Flower. Special flowering fertilisers that contain less nitrogen and more phosphorus are ideal at this time. However, excessive fertiliser applications should be avoided to prevent over-fertilisation. Observe the plant closely: yellow leaves can be a sign of nutrient deficiency.
- Bewässerung: The plant grows very quickly in the pre-flowering stage and therefore needs sufficient water. However, the soil should not be too wet to avoid root rot. It is advisable not to water the soil again until the top layer has dried.
- Licht: A stable light cycle is crucial during the pre-flowering phase. Indoor growers should slowly switch to the 12/12 light cycle to promote the transition to the flowering phase. Outdoor plants benefit from the longer daylight hours in spring and summer.
- Care of the plants: Remove dead or yellow leaves and ensure good ventilation around the plants to prevent mould growth. Now is also a good time to remove any male plants.
Proper care and fertilisation in the pre-flowering phase ensure that the plants enter the flowering phase strong and healthy.
Cannabis pre-flowering in outdoor cultivation: note the special features
The Cannabis pre-flowering outdoor differs from indoor cultivation in some respects, as the plants are exposed to natural light and weather conditions. Outdoor growers must therefore pay attention to a few special features in order to provide the plants with the best possible support during pre-flowering.
Tips for outdoor pre-flowering:
- Lighting conditions: Outdoors, the start of pre-flowering depends heavily on the natural light cycles. Outdoor cannabis usually starts pre-flowering when the days get shorter. In spring and summer, the plants get more daylight, which accelerates their growth process. To promote pre-flowering, the location of the plants should be chosen so that they receive as much sunlight as possible.
- Weather conditions: In outdoor cultivation, the plants are directly exposed to the weather. In the pre-flowering stage, it is particularly important to protect the plants from extreme weather conditions, as heavy rain, wind or hail can damage the sensitive pre-flowers. If bad weather threatens, a simple greenhouse or cover can be helpful.
- Bodenqualität: The plants draw a lot of nutrients from the soil in the pre-flowering stage. The soil should therefore be rich in organic matter and well-drained. Outdoor growers should regularly enrich the soil with organic fertilisers or compost to ensure the nutrient supply during pre-flowering.
- Schädlingsbekämpfung: Outdoors, the plants are more susceptible to pests and diseases. Pre-flowering is a good time to check the plants for pest infestation and use natural pesticides if necessary.
With careful care and consideration of the natural conditions, the Cannabis pre-flowering outdoor successfully and lays the foundation for a productive flowering phase.
Summary: The most important facts about cannabis pre-flowering
The Cannabis pre-flowering is a crucial moment in the plant's life cycle. During this phase, the plant shows its sex for the first time and prepares for Flower. Timely and accurate recognition of pre-flowering helps growers to remove male plants, adjust nutrient requirements and organise care accordingly.
The most important points we have discussed are:
- Pre-flowering marks the transition to the flowering phase and is decisive for the later harvest quality.
- Recognition of pre-flowering: Look for the formation of white hairs (female) or round balls (male) on the nodes to determine the sex of the plant.
- The Duration of pre-flowering is usually one to two weeks, but can vary depending on the variety and growing conditions.
- During pre-flowering, the nutrient requirements change. Now is the right time to switch to flower-promoting fertilisers with a high phosphorus and potassium content.
- At Outdoor-Anbau light conditions, weather conditions and pest control play a major role.
With this information, you are well prepared to successfully master the pre-flowering phase and set the course for a vigorous flowering phase. Remember to inspect your plants regularly during this time and cater to their needs. That way, nothing stands in the way of a successful harvest!
