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.

Male marijuana seeds
Males make themselves known at the beginning of the flowering stage, but a hermie plant may grow only buds except for just one or two tiny pollen sacs, or a few yellow hermie bananas.

Create Your Own Feminized Marijuana Seeds

Let’s Create our own feminized marijuana seeds

What are ‘feminized’ seeds?

Simply put, they are marijuana seeds created by breeding two female plants together. Since there are no male parents, all the offspring will be bud producing female plants. Feminized seeds ensure that you can count on every plant to produce buds, and don’t have to worry about removing male plants (which cause lower yields and seedy buds if allowed to pollinate your valuable females).

Feminized seeds are commonly available from marijuana seed banks for nearly every popular or famous strain. Breeders know that a lot of people just want to grow plants for buds, and don’t care about breeding or making their own seeds (which is one of the main reasons growers want male plants).

How do seed banks feminize their seeds?

How can you breed two female plants together?

The idea is to force a female plant to produce pollen. The male flowers (growing on a female plant) create pollen, which can be harvested and used to pollinate another female marijuana plant. The resulting seeds will all end up being female.

Can feminizing seeds cause hermaphrodite plants?

Growers can force a female plant to make pollen sacs, and the “feminized” pollen produced can be used to fertilize another female plant.

How do you force a female plant to make pollen?

There are two (semi)reliable ways to make female plants produce pollen:

  1. Induce feminized pollen chemically (Recommended): This would be the “professional way” to feminize seeds, and is how most reputable seed banks and breeders create feminized seeds to sell to the public. Mineral supplements such as colloidal silver and gibberellic acid are used because they cause a female plant to produce male pollen sacs if bud sites are treated daily for the first 3-4 weeks after the onset of flowering. This article will give you step-by-step instructions on how to feminize cannabis seeds using the colloidal silver method to creating your own feminized marijuana seeds.
  2. Rhodelization (Not Recommended) In the wild, some female cannabis plants will naturally start making male pollen sacs or “bananas” which can self-pollinate the plant. This happens if the plant is stressed, or if the plant is not harvested in time and buds start to die of old age. The plant is basically doing everything it can to save the next generation. Resulting seeds have a very high chance of herming and seeding your buds. This method is unreliable and not recommended but I did want to mention it as it is technically a way to create feminized seeds, however very unreliable.

But is there a dark side to feminized cannabis seeds?

One of the biggest concerns for growers when it comes to feminized seeds is that they will produce hermies instead of 100% female plants.

‘Hermie’ is a nickname for a hermaphrodite plant. A hermaphrodite produces both female buds and male pollen. The image shows a marijuana plant that has both male pollen sacs and female pistils growing from the same node.

Even the smallest amount of pollen in your grow room can seed your buds, just like a male plant would. A hermie plant can be a lot easier to miss than a male plant since it may just be a small part of the plant that’s is producing pollen sac(s).

Males make themselves known at the beginning of the flowering stage, but a hermie plant may grow only buds except for just one or two tiny pollen sacs, or a few yellow hermie bananas.

Is it True that feminized seeds can cause hermies? Yes!

Many growers believe that feminized seeds cause hermies, and there is some truth to that. In order to create a feminized seed, one of the parent female plants had to be forced in some way to produce pollen.

That pollen is used to pollinate another female plant, and the offspring of those two plants will all be female since both of the parents were female. That’s how you get feminized cannabis seeds. But it also means every time you have a feminized seed, that seed had a plant that was forced to hermie at some point in its genetic past.

There are different ways to feminize seeds, but only some methods produce seeds that hermie.

It’s important to understand that hermies can happen several different ways. And the different types of hermies affect what genes are being passed on to the seeds.

What Causes Hermies?

  • Bad Genetics: the plant comes from a line of plants that naturally create hermies
  • High Stress: high temperatures, light leaks, inconsistent light schedules, and other types of major stress can cause a perfectly healthy plant to hermie, although some plants/strains are more susceptible to stress than others
  • Over Maturing Plants: this is also known as rodelization as we touched on earlier
  • Chemical Stimulation: exposing a female plant to certain substances like colloidal silver or gibberellic acid during the early parts of the flowering you can force any female plant to create pollen. This is how seedbanks get female pollen to produce feminized seeds.

Seeds created from hermie pollen will turn out being female – at least as female as the parents.

Feminized seeds are susceptible to becoming hermies themselves when exposed to the same conditions as their female ‘father’ who produced the pollen. But since any plant can be chemically induced to produce pollen, it doesn’t mean that the ability to hermie in a natural environment is passed on to the seeds.

Only some feminized seeds come from parents with bad genetics.

Marijuana Seed Banks & Seed Breeders

Commercial breeders and seed banks use chemical stimulation to create feminized seeds. What that means is they put specific compounds on developing female plants to force them to produce pollen.

This technique works on nearly any plant, including plants that would never hermie naturally. So it can be used to take two plants with great genetics to produce female seeds. But the same process will also work incredibly well on plants that do hermie easily all on their own. That means it’s up to the breeder to test and make sure that they have a solid plant with unbeatable genetics before using this technique.

The pollen that results from chemical stimulation is then used to pollinate another plant and make feminized seeds. If the parent plants would never hermie without chemical stimulation than you have created feminized seeds that won’t ever make pollen in your grow room.

But if one of the parent plants was chosen because it does hermie easily than you’ll end up with seeds that hermie and the breeder might not have done any testing on the parents or the resulting offspring to even know.

Without testing, a breeder can’t tell whether they’ve created quality feminized seeds.

The Overview: How to Make Feminized Seeds

  1. Buy Colloidal Silver – The Best place to get it of course is on Amazon. Read our Colloidal Silver Review.
  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)
  3. Harvest ‘Feminized’ Pollen
  4. Pollinate Another Female Plant
  5. Wait

6 Weeks to Harvest Seeds

What about gibberellic acid? I’ve heard that works too. I am confident in the colloidal silver method and it works for making feminized seeds, because I use it myself. I have never used it I don’t personally know anyone who has tried making feminized seeds with gibberellic acid. From what I understand it can be used exactly the same way as colloidal silver. But I’m not sure exactly how to prepare a gibberellic acid solution so I chose to stick to sharing the information that I know about and what I know will deliver results for you to create your own feminized marijuana seeds.

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

Step-By Step Instructions for creating your own feminized marijuana seeds with pictures

Buy Colloidal Silver

Colloidal Silver is sometimes used as a dietary supplement, its safe and isn’t some crazy harmful chemical that you are applying to your plants. You must purchase colloidal silver that is a solution of at least 30 PPM (parts per million) of silver or higher.

Spray the bud sites (nodes) of your known female plant daily during first 3-4 weeks of the flowering stage (until pollen sacs form and start splitting open)

When you’re ready, switch your light schedule to flowering. 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.

As soon as you change the light schedule (and maybe even a day or two before) start spraying your plants thoroughly with colloidal silver at every bud site you want to form into pollen sacs.

Spray bud sites thoroughly, drenching them with colloidal silver every single day

Important! Keep spraying daily until pollen sacs open up. Don’t stop spraying early, even if pollen sacs appear to be already formed, otherwise they may not produce much pollen!

one-hand pressure sprayer / mister is really helpful for spraying bud sites evenly and thoroughly

You can choose to treat a single bud site or all the bud sites on the plant. Any untreated bud sites will develop into female buds as usual. If you want to smoke these buds, it’s incredibly important to avoid letting them come into contact with colloidal silver as that’s not safe to smoke. (Don’t worry, feminized seeds don’t contain any silver). I highly recommend letting the whole plant be your test subject so you don’t have to worry about that

Auto-flowering strains – If you’re feminizing an auto-flowering plant, start spraying daily when the plant is about 20 days old from seed. This is when most auto-flowering cannabis strains start making flowers.

Harvest Your Feminized Pollen

When pollen sacs are starting to crack and look like they’re about to open up (or if you can see one has already opened) then your pollen is ready for harvest!

When pollen sacs are cracking and opening up, you’re ready to harvest your pollen!

Pollen spilling onto a nearby leaf

One way to harvest your pollen is to gently and carefully remove all the pollen sacs. Let them dry for a week, and then put them in a resealable bag. If you shake the bag the pollen should easily spill out. You may need to cut a few open yourself.

How to Store Feminized Pollen: Moisture is your main enemy when storing pollen. It can help to double the mass of the pollen collected by adding regular cooking flour. This absorbs moisture during storage and as an added bonus, it will make application easier when you get to pollinating. If you triple-bag the pollen-flour mixture and stick it in the freezer (with a good nametag so you know where the pollen came from), your pollen can be stored for a year or longer.

Pollinate Another Female Plant

When your chosen mother is 2-3 weeks into the flowering stage, take a paintbrush and ‘paint’ your feminized pollen on the developing bud sites you want to pollinate. Bud sites (for both male and female plants) are located wherever you can see leaves meet a stem.

Only the buds that come in contact with pollen will grow seeds. You can choose to pollinate all of your buds or just a few on the plant.

Make sure that you’re touching all the female pistils/hairs with your pollen. Here’s a little video showing you exactly what this looks like!

6 Weeks to Harvest Seeds

It usually takes about 6 weeks for your feminized seeds to fully develop. Some plants are literally dying right as the seeds become ready, so to get the most viable seeds, you need to try to keep it alive until the seeds actually start dropping. The seeds can be used right away or stored in a cool, dry place for a few years. Don’t forget to label them with the date!

This seed is about to burst out of its calyx! This is what it looks like when the seed is exposed

Now you can germinate your feminized seeds and see if your feminized seeds produce something different than its parent(s) or if its an identical, amazing, bud producer exactly as you had planned.

And that is that, you have created your own feminized marijuana seeds just like the pros!

Before we wrap this one up, a few thoughts on basing your entire grow and future grows using your own feminized seeds.

Despite what some may believe or would like you to believe, breeding plants is not easy and requires a lot of time, knowledge and luck.

Without careful and thorough testing, it may be possible to accidentally select for cannabis plants that tend to herm (make male flowers or pollen) and cause seedy buds when you don’t want them to.

For each possible ‘mother’, clones should be grown in several different environments and tested thoroughly to make sure that the mother plant does not have any tendency to make pollen naturally in normal or stressful conditions. It’s okay if plants grow pollen sacs if induced chemically, but you don’t want plants that will start growing male parts on their own. Thorough testing of plant’s hardiness is always important when breeding, but it is especially important when breeding feminized seeds together.

If you don’t already have good strains to work with, buy seeds and start with reliable genetics to then start creating your own feminized seeds. Checkout the reviews for where to buy marijuana seeds here, or checkout the seedbanks below.
