Definition Of Rodelization Method

Rodelisation is natural technique utilized by expert cannabis cultivators to induce production of feminized seeds in female cannabis plants.

This method capitalizes on plant’s innate survival instincts, utilizing its natural urge to perpetuate its genetic lineage in face of adversity.

When female cannabis plant is exposed to stress or unfavorable conditions, it may enter self-preservation mode, leading to development of male pollen sacs.

These sacs then pollinate females flowers, creating seeds that carry predominantly females genetics.

In Rodelisation process, grower deliberately extends flowering phase of female cannabis beyond its usual timeline, causing weed to experience stress.

This stress pushes plant to generate male pollen sacs as last resort to achieve pollination.

Once these sacs mature and release pollen, pollen can be collected and used to fertilize other females, resulting in higher likelihood of obtaining feminized seeds.

Differences Between Rodelisation And Hermaphroditism

Differences Between Rodelisation And Hermaphroditism

Rodelisation and hermaphroditism are distinct phenomena that can occur in marijuana seeds, and understanding their distinctions is critical for successful cultivators.

Rodelisation refers to female plant’s production of male flowers or pollen sacs in response to stress, while hermaphroditism denotes a plants possessing both male and females reproductive organs.

Rodelisation can lead to feminized seeds, but occurrences are rare, whereas hermaphroditism can result in self-pollination and generation of seeds with the desired trait.

However, hermaphrodites are undesirable for growers as they can pollinate other plants, diminishing THC and CBD quality and yield of the crop.

Environmental factors and genetics may contribute to hermaphroditism, while rodelisation is natural process that some females undergo at end of their life cycle.

Factors That Influence Rodelisation

Successful rodelisation in cannabis plant cultivation is a result of careful management of several critical factors.

Factors That Influence Rodelisation
  • Environmental Stress: Rodelisation is often triggered by stressors such as fluctuating temperatures, nutrient deficiencies, and irregular light cycles.
  • Genetics: Genetics play a significant role in determining its propensity to undergo rodelisation. Some strains are more prone to this phenomenon due to their inherent genetic traits.
  • Maturity: Age of the marijuana is another factor that affects the likelihood of successful rodelisation. Rodelisation typically occurs when females are left unharvested past their peak maturity.
  • Grower Experience: Expertise and skill of grower can have a significant impact on outcome of rodelisation. A thorough understanding of weed biology, stress management, and environmental conditions is required for successful rodelisation.
  • Pollination and Isolation: Rodelisation can only produce feminised seeds if males pollen is absent from growing environment. It is crucial to isolate ones undergoing rodelisation from other that are producing pollen to prevent cross-pollination and ensure production of feminised seeds.

Can You Use Rodelisation On Autoflower Cannabis Seeds

Can You Use Rodelization Autoflower Cannabis Seeds

The answer is a resounding “yes,” but with a slight twist.

Rodelisation of photoperiod cannabis strains is a well-established practice, but when it comes to autoflower strain, the approach needs some special considerations to ensure success.

Autoflowering cannabis seeds are unique in that they are predetermined to switch from vegetative to flowering stage without being influenced by light cycles.

This trait requires careful attention when employing rodelisation technique.

Since these marijuana will automatically begin flowering, it’s imperative to monitor their progress and identify the ideal time to initiate rodelisation process.

Typically, you would want to start rodelisation when weed is nearing end of its flowering stage but has not yet begun to produce seeds.

This is the optimal time when weed is most likely to develop males pollen sacs in response to stress.

Although it may be challenging to induce stress in autoflowering strain due to their shorter life cycle and faster growth, careful observation and timely action can increase chances of success.

It’s important to remember that rodelisation in autoflowering strain may not produce as many seeds as with photoperiod. This is because autoflowering strain generally have smaller stature and produce fewer flowers.

However, seeds obtained from rodelisation of autoflower strain will still carry autoflowering trait and can be used for future cultivation.

When To Use Rodelisation In Cultivation

When To Use Rodelisation In Cultivation

Rodelisation is ideal choice when natural and stress-free approach to feminization is sought.

This method capitalizes on weed’s instinct for survival, prompting it to produce female seeds when under duress.

Typically, ideal time for rodelisation is reached when the weed reaches its flowering stage, and is not pollinated.

By prolonging the flowering phase, the weed experiences stress, leading to development of pollen sacs on females.

Consequently, pollen generated by these sacs is used to fertilize other females, resulting in feminised cannabis seeds.

Advantages And Disadvantages

Advantages And Disadvantages

Rodelization method in cannabis cultivation presents both advantages and disadvantages.

It’s imperative to understand these aspects to make informed decision about whether or not to incorporate rodelisation in your cannabis plant garden.


  • Natural Process: Rodelisation embraces natural response of marijuana to stress, eschewing the use of chemicals or artificial techniques. As result, it’s an environmentally friendly option for organic growers.
  • Cost-effective: Compared to other techniques, such as colloidal silver or gibberellic acid, rodelisation is affordable option for producing female cannabis seeds. It requires no special equipment or additional purchases, making it accessible to growers with limited resources.
  • Ease of Implementation: Rodelisation is straightforward process that can be implemented by growers of all skill levels. It does not require any technical expertise or advanced knowledge of strain genetics, allowing even novice growers to take advantage of this technique.


  • Low Success Rate: One of primary drawbacks of rodelisation is its relatively low success rate. While some will produce feminized seed as result of this method, it’s not guaranteed, and number of seeds produced may not be sufficient for large-scale cultivation.
  • Time-consuming: Rodelisation is slow process that requires weed to naturally enter self-pollination stage due to stress. This may extend cultivation period, leading to longer time investment for growers.
  • Risk of Hermaphroditism: Utilizing the rodelization method may increase risk of producing hermaphroditic marijuana. These contain both male and females reproductive organs and can lead to lower quality THC and CBD buds and reduced overall yield.

Other Techniques To Make Feminized Seeds

Other Techniques To Make Feminized Seeds

Cannabis growers have several other methods for producing feminized seed, each one promising higher probability of THC and CBD females in their cannabis crops.

Two popular techniques include the use of gibberellic acid and colloidal silvers method.

Gibberellic acid is hormone that plays vital role in weed growth and development.

By applying it to males, growers can stimulate formation of female flowers, leading to production of feminized seed.

To use this technique, solution of gibberellic acid is applied to weed apical meristem or growth tip during its pre-flowering stage.

Hormonal change triggered by the acid causes marijuana to develop female flowers.

This method is reliable and effective, but it may be challenging for beginners due to careful handling and timing required.

Another popular technique for generating fem seeds is colloidal silver method.

Colloidal Silver Method For Producing Feminized Seeds

Colloidal Silver Method For Producing Feminized Seeds

Colloidal silver is suspension of microscopic silvers particles in water, and it’s a powerful reaction tool for feminizing cannabis seeds.

By spraying colloidal silvers solution onto branches of chosen female during its early stages of flowering phase, you can induce production of pollen that can be used to pollinate other females.

To achieve optimal results, choose robust and vigorous female with desired traits and carefully apply colloidal silvers solution to its branches on a daily basis, ensuring complete coverage.

Within weeks, treated branches will begin to develop pollen sacs that can be harvested and used for pollination purpose.

This method has been proven to be highly effective in generating feminised seeds, as absence of male chromosomes greatly increases chances of producing female offspring.

Popular choices for feminizing sprays include commercially available solutions like GrowFem, as well as high-quality colloidal silvers products like Silvers Sol and Tiresias Mist.

The latter is specially designed for creating fem cannabis seeds in the cannabis industry and has earned a reputation for its effectiveness.

When choosing best colloidal silvers for feminizing seeds, make sure to choose one with high concentration of silvers particles, typically between 30-50 ppm. This is key to stimulating pollen production and ensuring best results.

To simplify process and ensure consistent results, consider using renowned feminizing spray like GrowFem. They’re designed specifically for this purpose and contain high concentrations of colloidal silvers to stimulate pollen production in female cannabis plants.

Colloidal silvers is a valuable tool for cannabis cultivators, as learning how to make feminized seeds with colloidal silvers can significantly enhance the efficiency and productivity of their growing operations.

Advantages And Disadvantages

While colloidal silver has gained popularity as a method for feminizing cannabis plants, it’s essential to understand its advantages and disadvantages to make the most informed decision.


  • High Success Rate: Colloidal silvers is renowned for its high success rate in producing feminized cannabis seeds, and applying it to your cannabis can effectively encourage the marijuana to produce only female flowers, yielding higher yield of cannabis seeds.
  • Accessibility and Affordability: Colloidal silvers is readily available and affordable for most growers. It can be purchased online or from local stores that specialize in health products or gardening supplies, making it accessible to growers of all skill levels.
  • Controlled Application: By using colloidal silvers, you have more control over feminization process. You can carefully apply it to specific branches, allowing you to choose which parts of the weed will produce feminized cannabis seeds while leaving other parts untouched.


  • Chemical Exposure: Colloidal silvers is a chemical solution, and its application exposes your plants to chemicals, which may not be ideal for those who prefer organic cultivation.
  • Stress: Applying colloidal silvers to your cannabis plants can cause stress, which is generally temporary but crucial to monitor closely during the feminization process to ensure they recover and thrive.
  • Non-consumable Flowers: Marijuana treated with colloidal silvers produce flowers that are not suitable for consumption, limiting their use to only seeds from treated ones and discarding rest of plant material to avoid health risks.

Increased Risk Of Hermaphrodite Plants In Cannabis Farming

Increased Risk Of Hermaphrodite Plants In Cannabis Farming

Environmental stressors are leading cause of hermaphroditism in cannabis plants. These stressors can include extreme temperature fluctuations, inadequate or inconsistent lighting, improper nutrient management, and physical damage to the weed. 

It’s essential to monitor and maintain optimal growing conditions to minimize risk of hermaphrodites in your cannabis garden.

Genetic predisposition is another factor that can contribute to emergence of hermaphrodites in cannabis farming.

Some cannabis strain are more prone to developing hermaphroditic traits than others. When selecting your seeds or clones, it’s essential to choose those with low likelihood of hermaphroditism to ensure healthy, stable, and productive crop.

To further reduce risk of hermaphrodites in your cannabis farm, consider implementing following strategies:

  • Regular inspection of your marijuana for signs of hermaphroditism, such as presence of both pollen sacs and pistils on the same marijuana. Early detection and removal of hermie can prevent accidental pollination and maintain quality of your crop.
