colloidal silver feminized seeds

How to make your own feminized seeds using Colloidal Silver or Rodelization

There are two main methods to create your own feminized cannabis seeds:

  • colloidal silver method or
  • rodelization (sometimes spelled “rhodelization” or “rodilization”)

Both the colloidal silver method and the rodelization method are described in detail below if you scroll down. Rodelization is a more “natural” way to get seeds, while colloidal silver gives you more control of the feminization process. Each of the methods has its pros and cons.

For whatever reason, when colloidal silver solution is sprayed regularly on female cannabis plants during the early flowering stage, she will grow male “balls” (which are full of female pollen) instead of growing buds.

This allows the grower to collect pollen from a female cannabis plant. You can use this all-female pollen to pollinate another female plant. With two female plants as parents, ALL the seeds will end up being female.

That is why colloidal silver allows can be used to create female x female cannabis crosses and produce your own feminized seeds.

Rodelization takes advantage of the fact that a female plant will try to pollinate herself as a last resort when she doesn’t get pollinated and is nearing the end of her life cycle. That is why sometimes older or stressed female plants grow a few male “balls” as a last-ditch attempt to self-pollinate. When successful, she will grow a few seeds.

These self-pollinated seeds will have gotten both sets of genes from the same female plant, so both parents will be female, and all resulting seeds with be female.

Why do you want feminized seeds?

When growing regular cannabis and trying to produce seeds, the resulting seedlings end up being about 50% male and 50% female.

This can be a big disadvantage for the cannabis grower because male marijuana plants do not produce very much THC or other psychoactive cannabinoids.

Therefore, when growing cannabis indoors, most growers will throw away all male cannabis plants as soon as they’re discovered. However, it’s easier to not have to worry about males since identifying and removing male cannabis plants can be a bit of a pain. Plus, male plants also take up precious space in the grow room until their gender becomes apparent when they are forced to start flowering.

Another problem with male cannabis plants is that they can accidentally pollinate your female cannabis plants which will cause them to concentrate on making seeds instead of making sinsemilla.

Sinsemilla is the term for cannabis flowers/buds that don’t contain any seeds. Dried sinsemilla is what most growers are trying to produce when growing cannabis.

So what can you do? If you create feminized cannabis seeds, then all the resulting plants will be female and you never have to worry about male cannabis plants again.

While there are a few different ways to create your own feminized cannabis seeds, for some people making your own feminized seeds may be impractical. If you are looking for a discrete, dependable seed bank, I personally recommend Seedsman who has a huge selection of feminized seeds.

How it Works

The main method used to create feminized seeds is to take a known female cannabis plant and force her to grow male pollen sacs and produce pollen.

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.

So far for me, it’s worked 100% of the time. Any male plants that do result when growing feminized seeds are probably genetic females that are growing with male characteristics.

There are several processes by which female plants will grow male characteristics. Some female cannabis plants will start growing male organs if they are left in flowering for too long, as a last-ditch attempt to pollinate themselves since they were not pollinated by any male plants.

Some female plants will also show male characteristics as a result of heat and light stress. But for the grower, the most convenient way to get a female cannabis plant to make pollen is to treat her with a solution known as colloidal silver.

Below I will first explain how to make feminized Cannabis Seeds using colloidal silver, then I’ll briefly explain the all-natural rodelization method, which is an all-natural though less reliable way to get feminized seeds.

Use Colloidal Silver Spray to Make Feminized Cannabis Seeds Like the Seed Banks Do

Pros:

  • You’re able to produce feminized seeds using any two female cannabis plants (even clone-only strains!)
  • You can produce seeds consistently
  • You can control how many seeds produced
  • Easy to make hundreds of feminized seeds if needed

Cons:

  • You will need to find a source of colloidal silver which will be used to spray the cannabis plants as they start flowering. Your main options are: buying colloidal silver directly, buying a colloidal silver generator, or making your own simple colloidal silver generator yourself (instructions below)
  • It is not safe to directly use/consume any cannabis which has come into contact with colloidal silver, though any seeds produced by a treated plant’s pollen are 100% safe.Note: Some space-starved pot farmers will use the colloidal silver to spray just the bottom branch of a cannabis plant so they can still smoke/use the rest of the cannabis buds. You can definitely do this, just be extremely careful not to get any colloidal silver spray on any part of the cannabis that you will be consuming. See this page (https://nccih.nih.gov/health/silver#hed2) for more information on risks involved with using colloidal silver.

When a female cannabis plant is treated with a solution of tiny silver particles suspended in distilled water, the plant will start to exhibit male characteristics.

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.

Some people drink colloidal silver for its health benefits and others use it occasionally on plants to help control bacteria, insects, and fungus growth on the leaves.

To take advantage of this, you thoroughly mist a female cannabis plant with colloidal silver every day right when she enters the flowering stage, she will start growing male “balls” full of pollen. Keep misting the plants daily until you see the beginning of male pollen sacs forming, usually around 10-14 days.

The concentration of silver ions in the water actually act as an ethylene inhibitor/antagonist on the plant, which forces the plant to create male pollen sacs instead of female buds.

After the balls start forming

You need to let the sacs swell like a big empty balloon.

You will be able to tell when they are about to open because the leaf section protecting the pollen starts to crack.

At this point, simply take the pollen sacs off and place them in a cool dry place for a week and let them start to dry.

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.

This method is great because it will force almost any female cannabis plant to show male characteristics.

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.

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.

You should, therefore, destroy the plant after the pollen has been collected.

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.

Here are the main things to keep in mind when using colloidal silver spray method:

  1. Make sure you spray the cannabis with a strong enough colloidal silver solution (at least 30 PPM of silver)
  2. Spray the cannabis thoroughly to almost drench all the parts you want to turn into pollen sacs
  3. Spray the cannabis regularly, at least once a day for 10-14 days, starting when you change the lights to 12-12
  4. Spray the cannabis with colloidal silver every day until you see signs of male pollen sacs forming. Some hardy strains may need over 2-3 weeks spraying before they ‘turn’.
Where to Get Colloidal Silver

Colloidal Silver is created by submerging two pieces of pure silver in distilled water, and then running an electric current between the two pieces of silver. The electric current will cause silver ions to be deposited in the water which creates a colloidal silver solution.

Buy Colloidal Silver: You can actually buy colloidal silver which has already been prepared and is ready for use. If you’re purchasing colloidal silver, try to find a solution that has at least 30 PPM (parts per million) of silver. However, buying Colloidal Silver that is already prepared can get expensive.

Buy A Generator Kit: A better option is to buy a relatively cheap colloidal silver generator to easily make your own colloidal silver. This Colloidal Generator kit comes with everything you need including silver. All you need to do is provide the water and a container.

Make Your Own: You can make your own colloidal silver generator at home. The diagram below should illustrate what you need to do.

Items Needed:

  • 9-volt battery
  • 9v Battery Connector (less than $2 at a hardware or electronics store)
  • Pure .9999 or 999 Silver (yes it must be pure)
  • Distilled water (yes it must be distilled)
  • Alligator clips (Optional: but will make things much easier)
  • Soldering Iron (Optional: only needed if you want to use alligator clips)

The diagram above will show you how to easily make your own colloidal silver to make your own feminized cannabis seeds

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.

If you don’t have a soldering iron and would still like to solder alligator clips onto your battery connector, then I recommend going to a hardware store and asking someone if they will help solder it for you.

Remember to keep your resulting colloidal silver solution away from any light or it will deteriorate and turn a dark gray color. If this happens, then you can no longer use the solution for creating feminized seeds.

Avoid most problems when making colloidal silver by:

  • using pure (distilled) water
  • using pure (999/.9999) silver
  • giving electrolysis enough time to work so you don’t get a weak solution (at least overnight)
  • making sure the solution has as little contact with light as possible until you use it

How to Make Feminized Cannabis Seeds Using Rodelization

Pros:

  • All-Natural
  • Very Simple

Cons:

  • Unreliable
  • May not produce many feminized seeds

The Rodelization method is all-natural and is the simplest method to create feminized seeds, but it is also unreliable and may not produce much pollen. Basically, the premise is that some female marijuana plants will start growing male pollen sacs/sex organs if they’ve been left in flowering too long (past the peak point of harvest). This is a last-ditch attempt by the marijuana plant to pollinate itself so that it at least produces a few seeds. You can collect these male pods and use the pollen inside them to pollinate other female plants. You pollinate female plants by evenly covering their buds with the pollen after they’ve been in flowering for 2-3 weeks. Females that are pollinated in this way will start growing all-female marijuana seeds. If you’re very careful, you can pollinate only some of the buds on a plant which will produce seeds, and leave other buds alone so they can still be used for consumption.

This issue with this method is that some strains of plants never seem to grow male characteristics naturally. Additionally, with this method, you’re selecting for plants that have a natural genetic tendency to show male characteristics. This can possibly produce offspring that are more likely to show male characteristics themselves which may or may not be what you’re going for. Lastly, even when you do get male pollen sacs from a marijuana plant in this way, there tends to be a lot less pollen than from a typical male plant.

The one great thing about this method is it’s completely all-natural so you can implement this strategy with an organic grow.

Producing Feminised Seeds Using Colloidal Silver

This is a condensed extract from the thread Purple Energy Beam vs. the Red Dragon .

I thought that the subjects of Feminised Seeds and their production, and the facts and fables about Hermies could do with some serious debate.

A journey into the production of Feminized Red Dragon seeds using Colloidal Silver.

10 November 2010

I started making the Colloidal Silver which was to be applied to one clone just before lights out.

Firstly, the victims . err . volunteers:

These two photos show 3 clones, one top-down shot and one side-on shot.
In both photos the middle clone is the one to be treated with Colloidal Silver, the two outside clones were placed under the Kessil H150 Magenta light 5 days ago on a 12/12 timer.

All three clones were the same size 5 days ago, now there is a definite difference as the 12/12 plants have a greater spread and have stretched as flowering approaches.

By the time the CS clone has produced pollen, the two seed bearers should have a reasonable number of pistils waiting to receive the pollen.

Just a quick lesson on how to make Colloidal Silver.

Find an old mobile phone charger, they have an output of around 5v DC which is perfect.
Snip off the plug that fits into the phone.
Strip the wires.
Attach 2 small alligator clips – the crimp-on style need no soldering and cost a few cents from and electronics shop (Radioshack/Dick Smiths ).
Attach small pieces of silver to the clips. (99.999% pure – jewellers wire, pure silver coins or ingots)
Pour Demineralised Water (cleaning products section of supermarket) into a glass – I used about 200ml.
Tape clips to inside of glass so that the silver (and NOT the clips) are immersed in the water.
Turn on charger and leave in darkness for 24 hours (silver reacts with light).

Next photo is my Colloidal Silver generator . followed by . well, I’m sure you can work it out .

. Watch this Space.

. The story continues.

26 November 2010

THE WAITING IS OVER

The three sisters were photographed today as it is a milestone.

For the last couple of days I have been more and more convinced that the clone being treated with Colloidal Silver was showing maleness, or at least a very restricted and confused femaleness.
Today I am willing to state that it is definitely producing male flowers.

These 2 photos are the 3 clones 16 days apart. They are in 4 inch pots so you can see how small they are and how little stretching has happened.
The 2 full females are very frosty and smell amazingly fruity . supposed to be like guava, but who the fuck knows what a guava smells like.

. and now for the pollen donor, (s)he is the same age as the other two plants but has has 7 days less 12/12 light and has been treated with colloidal Silver daily since 10th November 2010.
I made (and used) about 200ml of colloidal silver running the CS generator for 24 hours.

I made a second 200ml of Colloidal Silver and I will continue to apply the CS until the 200ml is finished – that should make sure that (s)he continues to grow some balls.

The waiting seemed like forever but it wan’t long really, just a bit longer and I can pollinate the seedbearers.
Looking at the number of pistils I think I am going to be happy with the number of seeds these babies will produce.

From what I read, you are supposed to give one large dose of colloidal silver to cause male flowering. Supposedly the application is enough to make the branch look dead for a couple of days. I personally have other ways of “stress hermaphrodisation²” but I would definitely like to see your results. Commercial breeders swear by the use of CS. If it works for you I will definitely give it a try.

(²My original use of the word ranks #1 on google.)

it works. done it many time..not this way but it does. i use a bigger charger and run less time. and i start the sprays just before flower time.

curious what the ppm readings came to with less volts and longer time.. not all works if not high enough. the safe for human sonsumption stuff isnt enough ppm.

Nah, all good questions . thanks for comming aboard for the ride.

All three clones were taken from the same mother plant on 13th October.

The mother was grown from a Barney’s Farm Red Dragon Feminised seed.

The colloidal silver is applied with a “spray bottle” totally drenching the plant/stem/nodes/leaves, the plants are so small it takes seconds to drench them.

Genetics of most breeder seeds are pretty stable, otherwise they would not be able to sell the seeds. No reason to think that self pollinating the plants (the same way that breeders do) would uncover any genetic instability.

. and thanks for the questions, I tend to assume stuff.

Would using regular pre-made colloidal silver work just as well? Stuff like this: HERE

One of my bro’s has to take this stuff orally on a regular basis because he got Giardiasis from being a dumb ass and drinking stream water that wasn’t treated lol.

O sweet so it seemed to work G.O.D?

Ill wait for 100% confirmation (although from your results it seems to work well already) and get me some silver to make the generator.

On a suggestion/idea:
Why not use a train control? You know those little grey 12Volt ones you can adjust the voltage on? That way you could experiemnt with different voltages and see whats the ideal voltage to get the most CS in the smallest time but at the highest [conc].

Then again, why fix whats not broke right? lol.

Still, be interesting to try this out now. Thanks for the well documented run down, as its good to see you put in all the info about the amounts used, times used, etc. IF you got a EC meter you think you could give your CS a lil test to see what its at?

The silver that I use are tiny ingots – I think they were 1 gram each, cost next to nothing on eBay.

This is the type of ingot I use >>>> eBay LINK

I have read that the commercial colloidal silver (for human consumption) isn’t strong enough to affect the plants.

Anyway, for the cost of a small bottle from a Health Food shop you can make a huge volume and be able to make it fresh every time you need it.

If I had a model train control I would have probably given it a go, but I didn’t – but I have more than one useless old phone charger and they work fine.
The voltage of the phone charger is less than what others have used to make the CS, but I wasn’t going to spend money on a more powerful power supply until I proved that it was needed.

If I needed gallons of CS, then my set-up may not be that great – but when I make a glassful at a time my system works perfectly.

The topic of Feminized seeds normally causes a difference of opinion as well as a few mis-truths by those who dislike Feminized seeds.

Statements saying that Feminized seeds are from hermies and will grow hermies are basically wrong and would hardly reflect good business practice from long established breeders in a very cut-throat seed market.

Cannabis plants have a strong compulsion towards survival of the species, and, should the plant encounter conditions that it is “genetically programmed” to recognise as threatening, it may produce flowers of the opposite sex.

Some plants have a high tolerance to stress/threats and others have a much lower tolerance, the ones with the lower stress tolerance are “more likely to go hermie” than those with a high tolerance.

A plant that hermies easily with very little stress will prodce seeds that will grow into plants with the same low stress tolerance. These seeds are not recommended to be grown.

If you have a plant that has survived being mistreated and only produced a couple of male flowers late in flowering, then those seeds are worth keeping. They will grow into female plants that can take a fair amount of stress, and if you don’t stress them they will most likely never grow a ball.

Some plants simply won’t respond to stress by producing male flowers. These are the plants that you would like to collect pollen from as the pollen should pass on the stress resistant gene.
Self pollination would be best as both “parents” are the same and the stress resistant gene is not diluted.
How to get the pollen?
Plants grown beyond fully ripe flowering often produce male flowers in a “last ditch” attempt at species survival. Pollen taken from such a plant wouldn’t tend to produce hermies as the pollen donor didn’t succumb to stress but lived to old age.

Growing plants well past their prime to harvest pollen is time (and resource) consuming and not easily controlled.

A more efficient, easily controlled, way is to induce male flowers without subjecting the plant to any stress.

This is where Colloidal Silver is useful.

Using Colloidal Silver on a plant has nothing to do with stressing the plant.
What happens (in terms that I can just about understand) is that the silver molecules bind themselves to copper molecules in the bud sites of the plant.
Copper is used for ethelyne production by the plant which is used for bud production in female plants.
By binding up the copper molecules and making them unavailable, the Colloidal Silver suppresses the ethelyne production and effectively tricks the plant into thinking it is male.
Again, it has nothing to do with stress, and if the plant didn’t have a genetic inclination towards being a hermie, then the seeds will not have the hermie trait either.

To use Colloidal Silver you simply spray the selected plant (or bud or branch of a plant) with colloidal silver before putting it under 12/12 lighting. Repeat the application until male flowers appear.

The fact that you can treat a single bud or branch on a plant and ONLY that area will produce male flowers allows you to harvest pollen and keep flowering the parent plant as a female.
Simply remove the affected branch as the male flowers are reaching maturity and stick it in a flower vase while the pollen sacs ripen, that way you control which flowers get pollinated.

I prefer to use clones for treating with CS as they are small and easily quarantined when needed.
