Be sure the strength is at least 15ppm, preferably 30ppm. Less than 15ppm produces male sacs with little viable pollen.
Treat feminized seeds as you would any other seed from germination to veg, and veg through flower. Observation is where it’s at now, you want the best plants for your garden. Ideally, setting up a separate vegetation/flower space where a number of plants can be grown lets your standard grow space continue with uninterrupted production.
When sexing begins, male pollen sacs will develop instead of female calyxes and pistils. Male plants mature much faster than females, and viable pollen can be expected within 3–4 weeks once the plant has been sexed. Some growers will spray until the plant shows sexual growth, just to be sure the method has worked. Make sure these plants are well-isolated from any flowering females. A burst pod can release millions of pollen spores, and it only takes one spore per hair to create a seed.
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.
To begin with, select a plant that has the characteristics you want to preserved. Feminizing clones is the usual practice as the growth, flowering, and resin characteristics from the mother are already known. There is no need for any vegetation time once a clone is well-rooted. Simply pot the clone into a small pot, give it a day or two to recover, and begin a 12-12 light cycle right away. A pollen-producing plant only needs to be small as cannabis produces copious amounts of pollen.
There are a number of harvesting methods employed to catch pollen.
- Cover the top of the pot with plastic or card to catch pollen as it falls, or modify a plastic drink cup to shroud the plant and catch falling pollen.
- Fix a clear plastic bag, perforated at the top for air exchange, around the whole plant.
- An experienced eye will remove each flower pod prior to it bursting completely open to be sure of catching every spore.
- Pollinating a female is the easy bit. Depending on how many seeds you want to make, there are a couple of methods that can be used.
- Using a watercolour or other fine, soft brush or even a cotton bud, dip into your pollen collection and gently apply to the chosen flower. Although thousands of viable spores will be on the end of the brush, enough to pollinate a whole plant, the trichomes on the surface of the pistils will greedily glue everything you offer them. So dip into your pollen stash a few times as you dust.
- For lots of seeds, put pollen in a bag and put over a whole branch or a whole plant, shake well, and leave for twenty four hours.
- It is possible to pollinate different branches with different pollens and have a breeder plant that has 1, 2, or 15 different crosses on it.
- It is also possible to self-pollinate the plant from which the male parts were created. This won’t produce as many seeds as pollinating a separate plant because less female flowers are produced and many are nonviable because of the feminization process.
The only bummer, unless you grow from clones, is that cannabis is wired to produce about 50% male seeds and 50% females. It is just the nature of the beast.
This is not the result of genetic or stress-induced hermaphroditism. They are genuine XX chromosome male bananas. With all the genetic information from the female and no Y chromosome, using rodelized pollen creates female-only seeds, although as with colloidal silver, an occasional male may appear.
Feminized cannabis seeds only produce female plants, which has a number of advantages. Find out how to do it with Royal Queen Seeds.
Unlike the rodelization method described below, you are not selecting for plants that show hermaphrodite traits. The genes of the plant are completely unaffected. This method will also produce a lot of pollen consistently compared to the rodelization method.
You can then take this all-female pollen and use it to fertilize other females. Because all the genetic material comes from females, you will end up with seeds that are at 99% female.
The one downside to this method is that it is not safe to use any cannabis that has come into direct contact with colloidal silver.
This solution of silver in water is called colloidal silver and can be purchased from a pharmacy/online or easily made at home . Or you can make it with a colloidal silver generator.
When you first connect everything, you may be surprised because it will seem like nothing is happening. You will know if it worked by the next day because the whole process will leave a silvery residue on your silver. You may need to use sandpaper or something else rough to clean your silver each time after creating a batch of colloidal silver.
You will also want to ensure that you clean off any remaining traces of silver off your equipment in case you accidentally contaminate another cannabis plant with silver.
The pollen will come out if you shake them about a little, or you can also cut open the sacs to get to the pollen inside.
Use this pollen to pollinate female plants and you will get all-female seeds that are a mix of both their mothers.
There are two main methods to create your own feminized cannabis seeds: the colloidal silver spray method or using rodelization.
