How to Make Feminized Seeds with Colloidal Silver
We describe an experiment which gave us about 1500 fem seeds from a 20-inch weed plant using colloidal silver and self-pollination
We were curious how easy it was to make feminized seeds with colloidal silver at home. So we ran a little experiment and got more than 1500 viable beans without any issues. You too can do the same and make a nice stash of female plant seeds for yourself by following these step-by-step instructions.
But let’s start with a bit of theory (you can skip this part and get down to business straightaway).

What are Feminized Seeds, and How are Seeds Feminized?
In nature, cannabis plants have two distinct sexes: male and female. However, only female plants produce buds for smoking. And if these buds catch some pollen, they will be subpar in quality because they will be full of seeds and not so big and also less resinous. That’s why growers who use regular seeds must watch their plants closely and cull all males in their garden as soon as they reveal their sex. Not very convenient, is it?
It all changed with the introduction of seeds that grow into fem plants in 99% of cases. They were named feminized seeds. So, are feminized seeds always female? In the majority of cases, yes, they are guaranteed to be female. However there are ways to make fem seeds hermie, meaning they will turn male or at least produce a few male flowers inside female buds. This can happen for seeds with weak genetics, or it can be a reaction to stress.
Male Plants no Longer Necessary
And this is exactly the feature that is used for manipulating feminised plants into producing feminised seeds. You don’t need any males for that. If you use a male to pollinate a plant grown from a fem seed, the result will be a bunch of regular seeds. And if you want fem seeds only, you should use one female plant as mother and another female plant as father. Or, alternatively, you can opt for self-pollination: when a single plant is used to both produce pollen and grow seeds.
There are several methods to make a feminised plant turn male. We won’t discuss here the most barbarian one — when breeders subject their plants to high levels of stress and they are turning hermie as a result. Although, believe it or not, the first commercially available seeds were made exactly this way, back in the early 1990s. You may guess the obvious drawback of such seeds: plants grown from them often become hermaphrodites even under normal conditions.
There is a less invasive method that modern breeders use. I’m talking about spraying a plant (or an individual branch of a plant) with a colloidal silver solution. This changes the chemistry inside the plant to make fem seeds male, and does so without any stress. As a result, we get seeds on a female weed plant without making them prone to hermies.
How to Make Feminized Seeds Using Colloidal Silver Spray
First, you need to make a colloidal silver generator and use it to produce the solution for your feminized seed spray. It’s unbelievably cheap, quick, and easy. Judge for yourself by clicking the link above and reading our step-by-step guide. The result should look more or less like this:
You should start using your feminised seed spray on a plant as soon as it starts flowering. You can apply it on all branches or just one. In the latter case, cover the rest from spatter. Please remember that silver is a toxic heavy metal and can poison you. You should never smoke colloidal silver weed.
It had taken us 4 weeks before we saw clearly that male flowers began to form. It was our first experiment, and we wasted many days applying the solution with a paintbrush. Don’t do that. It’s stupid. Just cover the rest of the plant with a piece of plastic and spray the chosen branch until it’s thoroughly wet. Do it once a day.
At some point, you’ll notice little green balls appear among female hairs (pistils): first closer to the top, then further down. Continue to apply colloidal silver spray until male ‘balls’ completely oust female pistils and start to look like a bunch of grapes. Only then you can stop spraying.
And this is how another branch on the same plant looks. It was not sprayed, so it only has female flowers:
After another month the male flowers will turn yellow and start to open:
Pollination is in full swing now, even if you don’t see the pollen. It consists of millions of tiny particles, and they fly everywhere.
Btw, pollinating buds at such a late stage of flowering is not the best idea. It would be better if the male pollen were ready a couple of weeks earlier, when the buds weren’t that mature. That would result in a) more seeds, b) less time spent, and c) better quality seeds. Well, we’re not sure about c), but some people on forums say it’s true.
When the branch with male flowers on it is fully mature, cut it, place it on a table, and rub it with your fingers until all yellow flowers fall off:
Then move the flowers this way and that with a credit card. The pollen will stick to the card’s edge. Shake it off into a separate heap:
To store and later use the pollen more conveniently, you can mix it with the equal amount of flour:
We put the mixture into an empty gelatin capsule and placed it in the refrigerator for storage..
Let me stress that we never used the pollen harvested this way to sprinkle on the plant. All pollination happened before we cut off the male branch. The seeds were fully mature 3 weeks after that. In this photo, you see only some of them. Later, we harvested at least as much.
How Soon Can You Plant Seeds After Harvesting Them?
We spent some time looking for an answer. People on forums say that the fresher the seeds, the lower germination rates. If you want to have good germination, give your homemade seeds some time to dry. Let’s say a month or two. It would be enough to degrade the hormone that prevents seeds from sprouting.
Our Experiments with Self-Pollinated Feminized Seeds
Over the next couple of years, we did a lot of experiments with our homemade seeds. The germination rates were always close to 100%, although, we must confess, we handled the process in a most off-hand manner. It’s understandable when the seeds cost you pennies.
We brought several plants to maturity and can say that they are very true copies of the parent plant. All fems, no hermies. All start to flower automatically after 2.5-3 weeks, all have the same height as the parent, the same length of the flowering period, the same structure of buds, and the same type of high. We liked the original plant, so we also liked its copies.
Making your own feminized seeds is fairly easy. If you want to make copies of an autoflower, this is the only way. If you want to copy a photoperiod strain, it works great as well, but you also have the option of taking cuttings. Cloning marijuana is quicker, but seeds are easier to give away or sell. Believe us: with our little harvest of seeds. we’ve made a lot of people happy.
How to make Colloidal Silver to make Feminized seeds
So I have doing some research on making feminized seeds and I came across this bit of info. I will not be able to try this for a couple months since I don’t grow indoors. Has anyone or someone they know ever attempted to make fem seeds using this method.
This is some info i found. Someone else wrote this stuff.
Thought it might be some useful info for anyone interested in trying to make those fem seeds.
Im using silver coins, but you can essentially use any form of silver including silver wire as long as its 999 or 9999 pure (i bought mine from my local Mint, but you easily get silver off ebay too.
Also, you dont need to solder alligator clips on, the important thing is simply that the wires are touching the silver so the electric current can flow through them, but i think the alligator clips add a nice touch plus they make it easier to hold the silver, so if you’ve got some spare alligator clips and have a soldering iron then I recommend it!
have reported excellent success with this method, and it’s no secret that colloidal silver has been used for a long time now to ‘reverse’ the sex of cannabis plants, although thanks to their help hopefully the process of making our own CS will no longer be shrouded in mystery!
What is Colloidal Silver?
Colloidal Silver is pure, metallic silver (the element), in particles of 15 atoms or fewer, each with a positive electric charge and attached to a molecule of a simple protein. These electrically charged particles of silver are extremely small, usually ranging from about 0.001 to about 0.01 microns in diameter, and are suspended in deionized water. The force of the electric charge is stronger than the force of gravity, so the silver particles remain suspended.
In a nutshell how is Colloidal Silver made?
You simply pass a small electric current through distilled water using a pure silver electrode (im using coins). That is essentially all there is to it. Contrary to popular belief, distilled water will conduct a small amount of electricity, allowing production of micro particulate colloidal silver.
What the hell does it have to do with cannabis.
We use Colloidal Silver (CS) for making FEMINISED SEEDS, which I’m a big fan of after having nothing but great success from them since i started growing a few years ago
(The basic idea being you regularly spray CS on a female to force it to create bananas ie. pollen . you then use that pollen to fertilize another female (or even itself, ie “selfing”), and the resulting seeds are feminised due to the pollen coming from a female instead of a male)
Also, there are some other substances that can be used to force male parts on female plants, including STS (silver theosulphate, which is silver nitrate + sodium theosulphate) and GA (giberillic acid), but CS is non-toxic, easy, safe and inexpensive to make at home, doesn’t require a DEA request form, and isn’t a controlled substance.
Csilver is available from your local chemist (in low parts-per-million though), and is drank for good health (the silver helps kill bacteria etc). But its PPM is too low for what we intend to use it for – feminised seeds! So we need to make our own with a higher PPM . no problems, we simply allow the electrical current to flow through the silver for a longer duration
TO MAKE A COLLOIDAL SILVER GENERATOR .
You will need: a 9V power adapter that outputs DC, two alligator clips, a soldering iron + solder. (If you dont have soldering iron you can simply wrap the wire around the alligator clip base in a coil and that will suffice, but youll get better contact if you solder it).
– Get a power adapter that has an output of 9V DC 600mA or thereabouts. Output must be DC, and 9V/600mA seems optimal from what I’ve read and been told
– Cut the end off and discard
– Split the main wire into its two smaller sub-wires (no need to pull them apart all the way though). Dont worry, we dont need to know which is positive/negative.
– Use wire-cutters to remove the plastic shielding/insulation to expose the actual metal wires, about 1 inch is enough
– Solder the wires onto alligator clips ($0.50ea from your local electronics store)
If you dont have alligator clips Haps suggested a good alternative – drill a hole into each coin and coil the wire around that instead.
TO MAKE COLLOIDAL SILVER .
– Get some distilled water. Do not use any other type of water due to impurities. At your supermarket you may find distilled water next to spring water, but it may also be in the ironing products isle as it is commonly used for steam irons.
– Attach each alligator clip to a chunk of PURE 999 or 9999 SILVER (i just got two 1oz coins from the local Mint, approx US$20ea, but 1/2oz coins wouldve been suffice – i didnt realise how big 1oz of silver was!)
– Make sure each coin is half-dunked in the water, but that the alligator clips themselves arent touching the water, then turn on your generator and leave it for about 7 hours. (goldking leaves his on “overnight” and thus probably gets an even higher PPM, but has had good results from it!)
The end result: the electrolysis causes microscopic silver particles to be suspended in the water (= colloidal silver aka CS). The rig basically looks like this when in use (the only thing in contact with the water is the silver, not the alligator clips or anything else):
It’s also recommended you use an airpump with a clean (not used for anything else) airstone to help keep the water moving.
Also you don’t want to leave the CS generator running TOO long or the silver particles in the water start getting too large – ~8 hours should be plenty.
USING COLLOIDAL SILVER TO MAKE FEMINISED SEEDS .
Start spraying your target plant with CS just before you send it into 12/12 flowering, and keep spraying every few days. I won’t go into details, but the CS causes the female to produce male flowers/pollen. Collect that pollen, and use it to pollenate another female (you can pollenate the same female that you CS’d (aka “self’ing”) and indeed you may have to if you have a clone-only strain, although that may lead to more hermaphroditic traits, but I wont go into details on that). Anyway, because you’ve pollenated a plant with pollen from a female, the pollen can only create female seeds.
There’s obviously a lot more to it than that but hopefully this brief explanation will help people understand the basic jist of it
ps. I don’t recommend drinking home-made CS unless you’ve done your homework because the PPM may be too high, which is great for making feminised seeds (we need a higher PPM for that) but may have risks with human consumption – too much silver can cause argyria, a condition of blue or gray discoloration of the skin, so always buy it from your chemist if you intend to use it medicinally. Also if you do drink it medicinally it’s recommended you also take additional probiotics (like Yakult), because the silver also kills a lot of the good bacteria inside you. So do your homework first!
don’t know what the RULES are for misting the plants,but i soak the heck out of mine when i spray,every day, not just a lil damp mist,thats why if i had to pay $20+ for a lil bottle at the health store, i could never afford to use CS.
i touch my ingots together to look for a miniscule spark arch to see if every thing has positive contact and is working. the spark, if there will be very very faint, kinda like rubbing a cat on the wall, the sparks are hard to see
