how do you get feminized seeds

Growing from feminized cannabis seeds is a space and resource-efficient way of getting all girls, all the time. Find out how to create your own feminized cannabis with Royal Queen Seeds.

Colloidal silver is by far the easiest to source or make. It is non-toxic, non-caustic, and can be bought from a pharmacy or easily online. The other solutions can be dangerous, difficult to get a hold of, and expensive—except gibberellic acid, which can be found in nurseries, but is not as effective as colloidal silver. But if you want to watch some freaky plant growth just for the fun of it, give gibberellic acid a try. It is a growth stimulant and makes plants stretch and stretch.

MAKING FEMINIZED SEEDS

With a bit of aforethought, it is possible to set up an efficient feminization breeding programme—and have female seeds from your favourite phenos on hand all the time. You never know, you might discover the next big thing!

Plants can be induced to grow male sex organs as late as four weeks into flowering. Though spraying one week prior to the light changeover is recommended for clones. If a plant grown from seed is being used, wait until the plant has sexed before spraying so you can be sure it is female.

Well, that is where the feminizing technique comes into play: two methods of manipulating the cannabis plant to produce only females from seed, every-time. To be truthful, it isn’t every single time. But 99% of the time is a pretty good number, and could be considered entirely male risk-free.

Cannabis plants that are pollinated naturally or with traditional breeding techniques can produce both male or female seeds. These are known as regular seeds and, as in most species, they occur with about an even split between the two sexes. That means cannabis cultivators starting with standard seeds have about a 50% chance of yielding a female plant from each one.

“In our search to find new genetics, Kannabia paired us with their feminized Russian Doll seeds,” say growers at Canada’s BlueSky Organics. “Every seed germinated, and now that we are in the late vegetative stage, these plants have an extremely hardy trunk preparing themselves for some massive buds.”

Male vs. Female Cannabis Plants

That efficiency is key for medical cannabis patients and hobby growers. Since most cannabis regulations limit plant counts, growers cultivating a small crop of cannabis for personal use want to ensure they’re getting the most out of their grow.

Male plants don’t just take up space in a garden, either. They can also sap time and resources from growers. When male and female plants are both present, growers need to cultivate both until their sexes are clear. While some strains will show early signs of their sex before flowering begins, most cannabis plants don’t begin to express their sex until they start to mature past the vegetative stage.

Historically, the way to learn more about the “hidden genes” contained in a male plant is to breed it to several well-known female plants, and see how the offspring compare to each other. The genes that don’t come from the known mother plant are assumed to come from the male. Another way of going about this is to take several clones of the same well-known female plant, and breed them with many different male plants to see which ones produce the best offspring.

Where to get Colloidal Silver (your options):

When you’re ready, change to a 12/12 light schedule in order to initiate flower formation. For photoperiod plants, wait until your plant is 5-6 weeks old before initiating the flowering stage. Some young plants seem to have trouble (and take much longer) to go through the feminization process, and their pollen may not be as fertile, so start with a more mature plant.

And although most cannabis strains (at least the good ones) display either purely male or purely female flowers, there are some wild populations (and some strains of hemp) that regularly produce plants with male and female parts on the same plant.

Now that you’ve gotten the overview, here’s the feminization process with detailed step-by-step instructions…

2.) Spray the bud sites of your known female plant daily during first 3-4 weeks of the flowering stage (until pollen sacs form and start splitting open) – After switching to a 12/12 light schedule, choose bud sites on your known female plant, and spray/drench them daily with colloidal silver (or gibberellic acid). As the treated flowers develop, they will form into male pollen sacs. Untreated bud sites on the plant will form into female buds as usual; however, these buds are unsafe to smoke unless you’ve been very careful to make sure they didn’t come into contact with colloidal silver or gibberellic acid during the feminization process.

Another big advantage in the wild of having separate female and male plants is sexual specialization. In other words, plants are able to evolve male and female traits separately, so each type of flower can become more specialized at its unique “job.”
