Throughout much of the 20th century, cannabis blooms were frequently laden with seeds. It wasn’t until the 1970s that a cannabis cultivator discovered the method to cultivate seedless cannabis blooms. The key lies in preventing female cannabis plants, responsible for the cannabinoid-rich buds we cherish, from being pollinated by male pollen.
Not only do fertilized female cannabis plants yield seed-laden blooms, but they also exhibit significantly lower levels of cannabinoids, terpenes, and flavonoids. This occurs because the plant expends valuable energy on seed production that could otherwise be allocated to bud formation.
It’s evident that most cannabis cultivators desire an all-female crop. To achieve this, some opt for feminized seeds, which are specifically engineered to yield only female plants. Nonetheless, feminized seeds tend to be pricier than conventional ones, and some argue that plants derived from feminized seeds may have diminished genetic diversity, thereby increasing the risk of genetic abnormalities.
Thus, if you’re cultivating from conventional seeds, it’s imperative to identify and remove male cannabis plants before they can disperse their pollen and jeopardize your harvest.
Recognizing Gender in Cannabis Plants
With the introduction of feminized seeds to the market over twenty years ago, many cultivators found relief in no longer needing to discern and discard male cannabis plants from their crops. Prior to this innovation, all marijuana seeds were what we now refer to as regular, capable of producing both male and female plants. However, in most scenarios, growers have no use for male plants; in fact, they actively seek to distance them from their cultivation space to prevent pollination of the female plants, which would result in seed-filled buds—a circumstance undesirable for most home cultivators unless they aim specifically to produce seeds.
Hence, it becomes imperative to promptly identify and eliminate male plants upon detection. This practice ensures a genuine “seedless” harvest: buds completely devoid of seeds, thus maximizing their cannabinoid and terpene content. Vigilance is crucial, particularly upon observing the initial signs of flowering or the early signs of female plant development when transitioning to the flowering stage in indoor setups. Let’s delve into the specifics of identifying male plants and the optimal timing for their removal.

First stage for detect cannabis sex
In the realm of cannabis cultivation, determining the sex of a plant at an early stage is pivotal. Typically, cannabis plants initiate flowering in response to prolonged night periods, signaling their transition to the flowering phase and revealing their gender unequivocally. However, sexual maturity in plants occurs approximately six to eight weeks after seed germination, independent of any photoperiod alterations. This essential knowledge removes the need for stressful interventions like cuttings or photoperiod adjustments to determine plant sex.
Once plants reach the fifth or sixth stage of leaf development, typically around the two-month mark post-germination, they attain sexual maturity. At this juncture, the plants have likely already exhibited their gender characteristics. Barring instances of stress-induced hermaphroditism, the gender identified at this stage tends to persist throughout the plant’s lifecycle. Mastering this technique over time enables growers to diagnose the sex of marijuana plants at an exceptionally early stage.
However, it’s possible that you may not be able to discern the sex until the flowering stage begins. During this period, careful observation becomes crucial as you’ll need to inspect the plants daily to determine their sex promptly. Typically, one of the initial indicators that the plant has entered the flowering phase is the loss of symmetry in its nodes, which no longer grow opposite each other but rather alternately. This adaptation prepares the plant’s structure for the development of the coveted bud tails.
Another significant sign of flowering is the emergence of the first preflowers, usually located where the buds originate from the main stem. This stage demands accurate identification and removal of male plants without error. While experienced growers may detect the sex of a plant earlier than novices, there’s ample time between identifying males and the point at which they could potentially pollinate your crop, allowing for their safe removal.
It’s advisable to thoroughly inspect the entire plant, not just the top, and conduct subsequent inspections every 2-3 days during the initial 2-3 weeks of flowering to prevent any surprises. Additionally, this routine enables the detection of potential hermaphrodite specimens, which are more challenging to identify as they may produce only a few male flowers on certain branches.
Recognizing Female Cannabis Plants Before Flowering
Determining the gender of marijuana plants before they enter the flowering stage is crucial for growers. Here are three primary methods to achieve this:
- Begin with feminized seeds or clones, ensuring a 100% chance of obtaining female plants.
- While genetic testing can offer early identification of plant sex, it may not always provide reliable results and can be a costly endeavor.
- Inspect the preflowers upon emergence, particularly effective with strains that exhibit rapid development. Look for delicate white hair’s indicative of females or spade-shaped flowers characteristic of males, typically found at the junctions where leaves meet the stem.

For have female plant use feminized seeds or clone
The most reliable method for determining the gender of your plants before they mature is through cloning. This involves taking a clone from any plant, which can be done with both cannabis seeds and clones, ensuring all-female plants. This approach offers numerous advantages, whether you’re a small-scale grower or a large commercial operation.
By cutting one of the branches and placing it in a small cup with growing medium, you can encourage root development over a few days. Once the clone has established roots, it should be placed under a 12/12 light cycle.
As it matures, the plant will reveal its gender. Since clones share the same DNA as their parent plants, they will exhibit the same gender. However, it’s important to note that this method isn’t applicable to autoflowers, which initiate flowering based on age rather than photoperiod. If your aim is to cultivate as many female plants as possible without breeding, using feminized seeds or clones is the most practical approach.
3 Cannabis Strains for Growing Female Plants
As we mentioned before, the best way to have female plants is by growing feminized seeds. With this you will avoid the appearance of males in your crop, and you will also ensure great harvests. Now we leave you here the recommendation of 3 feminized genetics that you should grow in the next outdoor growing season or if you are a gardener with a grow room, indoors.
