This is what it looks like when the seed is exposed
4.) Pollinate Another Female Plant – At this point, take the feminized pollen you’ve collected and use it to pollinate a female plant that has been flowering for about 2-3 weeks (full detailed instructions with a video on how to do this below). Although it’s possible to pollinate the same plant as the original, it’s not recommended in part because the timing doesn’t match up (pollinating buds late in the flowering stage doesn’t produce many seeds). It’s best to pollinate a different female plant that you started budding a few weeks after the original. This increases the number of seeds produced as well as gives the new female plant enough time to develop them to maturity. It also increases genetic diversity compared to self-pollination.

As of yet, I haven’t seen any of these claims backed by actual personal experience, or any real-life examples showing why using feminized seeds is not a viable way to breed new strains.
Spray bud sites thoroughly, drenching them with colloidal silver every single day. Bud sites are located wherever leaves meet stems.
After testing with several pairings, you start to get an idea of the hidden genes a male plant has to offer to its female offspring. This time-consuming process of documenting and identifying good male plants is why proven stud male plants are one of the most valuable and closely guarded types of clones available today.
What about gibberellic acid? From what I understand it can be used exactly the same way as colloidal silver to induce female plants to produce pollen, but I don’t know the recipe for an effective gibberellic acid solution. On the other hand, I know that this exact colloidal silver method works for making feminized seeds. That’s why I’ve only included instructions for colloidal silver. If you’ve used gibberellic acid to make feminized seeds; we’d love to hear from you.
Generally speaking, there is no way that you can determine the difference between male and female marijuana seeds in the initial stages of planting. In addition, you are also not able to change the gender of your marijuana deeds. The concept of having feminized marijuana seeds is to maximize the female seeds that will be part of your marijuana crop. Why would you want female marijuana plants? Well, these are known to have a higher level of THC content. Male plants have reduced THC content and for that reason, female plants take precedence over male plants. With cannabis seed feminization, there are several pollination techniques that the marijuana grower can use for a favorable outcome.
Each of these methods should be successful, if used in the right way to produce female marijuana plants. Let’s quickly look at each method briefly.
Buying the Right Cannabis Seeds
It’s important to learn how to feminize seeds so you can save time on your grow. When the traditional fertilization methods are used to grow your marijuana plants, you have less control over the gender of future marijuana plants. That is why many marijuana growers take extra steps so you receive female marijuana plants at the time of harvesting. To do it yourself, feminize seeds prior to your harvest.
Gibberellins are hormones that affect cannabis plants throughout their growth cycle. Some gibberellic acids such as GA3, 4, 5, and 7 can induce the growth of male cannabis flowers when sprayed directly on female plants before the flowering period. Most growers use GA3, the most widely available and effective of the gibberellic acids. Use a solution of 0.1 gram of GA4 per liter of distilled water. Ed Rosenthal recommends spraying the top of plants for five days in a row then changing the photoperiod to induce flowering.
Using Chemicals To Feminize Seeds
Another type of seed, a regular seed, is a result of natural pollination and breeding male and female seeds together. Cannabis growers working with regular seeds have a 50% chance of either yielding a female or male marijuana plant. Growing from regular seeds isn’t the best option if you’re looking to strictly grow cannabis buds. While male plants serve their specific purpose to pollinate females, they don’t produce the trichome covered flowers that female plants do.
