How To Make Feminized Cannabis Seeds Like The Pros

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.

MAKING FEMINIZED SEEDS

Growing cannabis is all about resinous flowers, trichomes, and rich cannabinoid profiles. These splendid characteristics can only be found on the female flowers. Having gardens full of robust, un-pollinated sinsemilla females means jars full of mind and body-friendly, crusty nuggets.

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.

Wouldn’t it be sweet if it was possible to grow all females from seed, every plant, every time?

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.

The general practice behind feminization is that female plants are forced to produce pollen, which is in turn used to pollinate other female plants. The outcome? Resulting seeds will be feminized, with no risk of further pollination.

WHY FEMINIZE?

Feminized seeds are super efficient for indoor and outdoor gardeners. Area, time, and resources aren’t being given to plants that will be thrown away two weeks after the 12-12 flip. Similarly, outdoors where a large plant can consume a lot of time and resources in upkeep prior to the autumn show of flowers, feminized plants are also a good way to reduce guerrilla crop pollinating. There’s nothing worse than bush-bashing out to a well-hidden crop only to find a rogue male or two have impregnated every female plant.

INHIBIT THAT ETHYLENE

“Applications that reduce the ethylene level in tissues or antagonise the action of ethylene causes the formation of male flowers instead of female ones” — Paraphrase, Byers et al., 1972.

There are a number of solutions that can be sprayed on female plants to create male pollen sacs: benzothiadiazole, gibberellic acid, silver thiosulphate, silver nitrate, and colloidal silver.

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.

TECHNIQUE 1: COLLOIDAL SILVER

Colloidal silver is a distilled water-based solution in which microscopic particles of silver are suspended. The nature of colloids means the particles will never settle out and can’t be removed by normal filtering. Colloidal silver is available commercially, or you can make your own if you want to totally geek out (see how-to section at the end). It has numerous uses as an alternative medicine. For example, it is used to soothe burns, as an antiseptic and digestion stimulant in people, and as a fungal control in horticulture.

Be sure the strength is at least 15ppm, preferably 30ppm. Less than 15ppm produces male sacs with little viable pollen.

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.

Hint: Make two clones once a plant has been selected, one to be feminized and one to be left for pollination. This way, a separate breeding space is created and accidental seeding of other plants, or an accidental sneeze pollinating a whole grow cupboard, is avoided.

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.

Spray the plants to be feminized with colloidal silver every day, and three times a day if you can manage. Soak them well. Do this for two weeks, then leave the plants to grow as normal. Some growers report getting results after spraying for only 5–10 days.

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.

DON’T SMOKE IT

Once the plants have been sprayed with colloidal silver and the pollen is collected, they are write-offs—86 them and don’t smoke them. Giving them a thorough rinse will not work. The colloidal silver is a systemic treatment absorbed into the plant through the foliage and not a topical application. Be safe and bin them.

TECHNIQUE 2: RODELIZATION

Sinsemilla is an unnatural state for cannabis. Without human intervention, it would be rare to find an unpollinated female in the wild—unless it was sterile. When sinsemilla plants are left to go beyond their desirable maturation stage by a number of weeks, the plant, through whatever amazing processes evolution has bestowed, knows it has not been pollinated. As a last ditch effort at propagation, it will produce male pollen sacs in an effort to self-pollinate.

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.

HARVESTING POLLEN AND POLLINATION

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.

GROWING FEMINIZED PLANTS

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.

Plants bred using feminization are homozygous. This can have two effects that can’t be assessed until the seeds are grown. Homozygosity will increase the dominant or recessive traits of the parent in the progeny, so features you don’t want and do want can be amplified. Genetics is a weird, weird thing.

Just as with standard male to female crossings (which is a heterozygous process), a number of plants will need to be grown and the best selected for mother plants and future breeding. With enough room, hundreds if not thousands of new plants can be grown in order to select the best of the best phenotypes.

FEMBOTS RULE

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!

MAKING YOUR OWN COLLOIDAL SILVER

The easiest and relatively inexpensive way—considering how much money is potentially saved by not growing resource and time-consuming males—is to buy a colloidal silver generator, which is the no-fuss plug and play option. Or, make your own, which is quite straightforward and doesn’t require any special skill.

Colloidal silver is formed by passing a current from a pure silver electrode through distilled water. This simple electrolysis is all there is to it. Although distilled water does not conduct electricity very well due to its lack of mineral content, enough is passed through to create micro silver particles and silver ionisation. Sounds technical, but it really isn’t.

How to Pick Male Plants and Make Cannabis Seeds

Why Every Home Grower Should Make Seeds (At Least Once)

I encourage every single grower to make seeds for themselves. A lot of people have been asking how, so I put together these basic tips. Hopefully, it helps a lot of people and is fairly straightforward. This isn’t meant to make you a breeder or share all my techniques or secrets, this is to familiarize you with the process of creating seeds.

It’s easy to make your own cannabis seeds at home!

It’s a shame that many grow books tell you only to throw away your males. New growers may not know, but anyone who’s grown for even just a few years gets to the point where they wish they still had something they grew in the past, which is no longer available in seed or clone for whatever reason. The older you get the more it happens. Seed lines disappear entirely once they run out, and due to people not making their own. It’s good to be self-sufficient.

While it’s always fun to check out the hard work of your favorite breeders and their strains, it’s equally as important to pollinate a branch or two for yourself here and there and see what magic you can create or preserve. Please share this article if it helps or inspires you. Big agriculture is coming to the cannabis growing world and has the ability to change the plant forever once contamination happens, just like in the veggie world. We are losing genetic diversity fast as thousands of unique strains are lost. Please do your part if you are passionate!

How to Make Your Own Cannabis Seeds at Home

These are basic starting points for the home grower. I believe every person who grows cannabis needs to have this skill. Every strain goes away over time when people don’t make more seeds. Growers should know how to make their own seeds for preservation and sustainability. These skills can go a long way. The precursor to serious breeding is the basic technique of creating the seed.

1.) Grow Male Plants

Male plants can be grown in very basic conditions in an isolated space, then flowered for pollen. Males can be started flowering next to females with a close watch for the first week or two, but be careful and remove them before pollen sacks form, bursting open and pollinating everything.

Branches can be cut off and put into a cup of water on a windowsill or under a CFL bulb, even under veg light cycle once they are in bloom. Pollen can be collected within a week from these branches, saving lots of space. Males can also be cloned or flowered very small based on your needs.

Best, however, is flowering the males in their own tent or space. With a carbon filter and negative pressure, and careful practices, you can avo >(More on best male plant selection below)

2.) Collect Pollen

Pollen can be collected by tapping a budding branch gently over a piece of paper. Pollen will spread easily in the air, so make sure to turn off all fans. Visit males only after tending to female plants so you don’t accidentally bring any stray pollen on your clothes or hair!

3.) Pollinate Buds

Take out your female to be pollinated or shut off all circulation fans. Gently apply pollen to a labeled branch. The pollen must meet the white flowering hairs to create seeds. Week 3-5 is best to pollinate, and you can do a single bud or branch per plant and keep the rest seedless.

Every pollinated branch should be labeled properly, your memory will not last as you think it will. A proper branch label includes dates, strain names, breeder/sources, and has the female listed first and male listed second. An example label looks like this: 4/20/2015 – Star Pupil (Mass Medical Strains) x Prayer Tower Sativa 9 (Bodhi Seeds) and the label should be kept with the seeds when they are finished. As years go by, you will be thankful for the dates and breeder information, which can escape our memory on occasion.

4.) Deactivate Stray Pollen

Water generally deactivates pollen, wash clothes and shower if needed after handling. 3+ hours after pollination, the plant can be sprayed down with water to deactivate stray pollen and can be brought back into grow room and fans turned back on.

Avoid spreading pollen unintentionally. It can get everywhere!

5.) Collect Seeds

Seeds are done in 2-6 weeks and should be dried in the bud when the plant is harvested. Seeds should be sproutable within one month of drying.

What strains should I use?

Any strain with traits that you like, which speaks to you, or seems like a good cross, means your intuition is telling you something. Starting with stabilized or homogeneous lines is always a benefit. Certain genes such as Cookies, OG, and Diesels, are full of hermaphrodites and should be used with caution, only to be bred with if they are really your #1 passion. Follow your heart.

Crossing two unrelated strains for the first time is called an F1. Crossing a brother and sister F1 of the same strain creates an F2, and so on. Selections play a huge role in what the outcome will be. Making F2 seeds of an F1 you purchased, will not give you the same seeds. Rather, you will see new phenotypes resembling some of the parents and their parents, etc. With huge potential to find new special plants within.

Many combinations will work great, and some will not. If you fail, try again, selecting new parents. Each combination is unique. A and B might work great together, and C and D might work well together, there’s still a possibility that A and C combine to create junk. Every parental combo is unique!

If you see a unique trait that you like, make seeds!

Selection Techniques

Female Plants

Selecting a good female is easy, flower female plants from seed and again from clone to test stability. Smoke test is important. A potential mother plant should have all the high-quality traits that matter to you. Hermaphroditic plants are to be avoided.

Female plants to be pollinated should have all your ideal traits. Use only your best females.

Male Plants

Selecting a male, you have to use your senses a lot. The ones who grow best and smell best are a good starting point. Structure and root growth are important. Hollow stems may indicate high THC potential. Cut the top off a couple nodes down and find out. First showing or fastest flowering males are generally discarded. Very slow blooming late males are often times more recessive although not always. I like them. Males will start to drop pollen before they are “done” flowering enough to see their true traits. As a beginner, you can use the pollen at any stage, but those doing real selections are advised to always flower your males for weeks after the pollen starts.

For male selections, a strain you’ve grown before and enjoyed the females is a safe starting point.

Watch for resin production, look at how the flower clusters stack and produce. The male flowers form similarly to female flowers, large yield potential is often apparent in largely formed male clusters that can look almost like female buds from a distance. The more males you have to choose from, the more fun you will have!

Male plants can be a lot of fun to grow, too. Just like the females of the genetics they come from, they all have their own characteristics and unique traits. Once you get into “hunting males” you could get hooked! Some of my prized male selections from over the years are shown here. You’ll see resin production and traits of large floral clusters, as well as unique coloration!

For more advanced breeding selections, I recommend starting ideally a few hundred seeds. (For beginners, as many as you can is great, will help you find the best ones you can. Use your intuition!) Plants can be weeded out every few weeks selecting only the best contenders to flower out, and a lot can be achieved in a spare tent or closet this way, while still selecting through large populations! Clones of a prized breeding male may be kept in veg the same way females are, to be used again and again once their offspring are proven good! This is how a breeder can create the same batch of seeds for years and years, by using the exact same parents held in clone form.

Conclusion

These tips are just the beginning, and the purpose isn’t to teach you how to breed, but to teach you how to learn your own path and style of creating seeds and preserving our very special plant. The seeds you create will always be a very special grow for YOU.

Making your own seeds is more important than ever. We must do our part to preserve the natural genetic diversity of this healing plant as it has evolved for millions of years. Home growing is an important skill as commercial and medical cannabis is increasingly full of toxins and scary new technology. Please grow responsibly with love.
