Soma way (over flowering)
Feminized seeds occur as a result of stress, other than genetics. All cannabis plants can and will make male flowers under stress. Certain strains like a higher PH, some like a lower one. Some like a lot of food, some like a lot less. There is quite a lot of variety in marijuana genetics, and you can?t treat every plant the same way.
It takes many harvests before you really get to know a particular strain. Just like getting to know human friends, it takes time. I have grown strains for a decade and am truly getting to know every nuance the different plants exhibit. I can recognize them from a distance. I must say that I get a lot of help from my friends, both in making seeds and learning new and better ways of working with this sacred plant.
I named this new method ?Rodelization? after a friend who helped me realize and make use of this way of creating female seeds. After growing crop after crop of the same plant in the same conditions, I noticed that if I flowered the plants 10-14 days longer than usual, they would develop male ?bananas?. A male banana is a very slight male flower on a female marijuana plant that is formed because of stress. Usually they do not let out any pollen early enough to make seeds, but they sometimes do. They are a built in safety factor so in case of sever conditions, the plant can make sure that the species is furthered.
stress the plants by going 2 to 3 weeks past the ripe flowering stage(this will produce male pollen sacs on the females-they then can be collected and used to pollinate. Since the female was stressed to produce male flowers, When back-crossed there is no need of worrying that the offspring(seeds) will produce feminized Hermite plants unless the original mother had herm traits in her strain line
To me a male banana is quite a beautiful thing. It has the potential of making all female seeds. Many growers out there have male banana phobia. They see one and have heart palpitations, they want to cut down the entire crop or at least take tweezers and pluck the little yellow emerging devices out. I call them ?Emergency Devices? because they emerge at times of stress.
In the Rodelization method, the male banana is very valuable. After growing your female plant 10-14 days longer than usual, hang them up to dry, then carefully take them off the drying lines and inspect for bananas. Each and every banana should be removed and placed in a small bag labeled very accurately. These sealed bags can be placed in the fridge for one to two months and still remain potent.
For the second phase you need to already have a crop that?s already 2 ? weeks into flowering. Take your sealed bag of pollen out of the fridge, and proceed to impregnate your new crop of females. To do this, you must first match the female plant and the pollen from the same strain in the previous crop. Shut down all the fans in the grow room. Then take a very fine paint brush, dip it in the bag of pollen, and paint it on the female flower. Do this to each different strain you have growing together. I have done it with ten different kinds in the same room with great success.
I use the lower flowers to make seeds, leaving the top colas seedless for smoking. This method takes time(two crops), but is completely organic and lets you have great quality smoke at the same time you make your female seeds. If you?re one of those growers that has never grown seeds for fear of not having something good to smoke, you will love this method.
You can also use this pollen to make new female crosses by cross pollinating. The older females with the bananas can be brought into the room with the younger, un-pollinated females when they are three weeks into flowering. Turn all of the circulation fans on high, and the little bits of pollen will proceed to make it around the room. Do this for several days. Six to seven weeks later you will have ripe 100% female seeds; not nearly as many as a male plant would make, but enough to start over somewhere else with the same genetics.
As a farmer who has been forced to move his genetics far away from where they started, I know very well the value of seeds. My friend Adam from THSeeds in Amsterdam has a motto that I love to borrow these days: ?Drop seeds not bombs?.
Colloidal Silver Method (CS)
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.
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):
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.
LIGHT-POISONING METHOD12/5.5/1/5.5)
During the first three weeks of flowering, turn the lights on for an hour during the middle of the dark period. That is, 12 hrs. on, 5.5 hrs. off, 1 hr. on, 5.5 hrs. off, and repeat for the first 3 weeks, after which you may return to the normal 12/12 light cycle. This causes a plant to go "hermie" and pollinate itself, as well as any other female in the room. You must use plants originating only from female seeds or clones to ensure that no male chromosomes are present. The resulting seeds will produce NO MALE PLANTS!
Making marijuana Seeds
How easy is it to make seeds? It's easy if you have healthy plants and a stable growing environment. When your male plants burst their pollen sacks in your grow room they'll pollinate the female flowers. You can also administer pollen directly to your females if you prefer.
Collecting and Storing Pollen
Pollen can be extracted from male flowers as soon as they open: you'll see the male flower open out from its calyx. It is best to gather pollen after it falls from the pod onto the leaves. You can shake the pollen onto the female flowers to pollinate them or grow your males separately and store their pollen for future use.
Film canisters are great for storing pollen. You can save pollen in a canister for the next harvest. Although it can be stored in the freezer for as long as months, pollen is best used within six months of collection. Pollen has been known to keep for longer than 18 months, but is usually not viable past this time.
Collecting and Storing Seeds
If you have pollinated your plants, at the end of the flowering stage the bud will contain seeds.The seeds should be gray, tan or dark brown in color.They may also be striped, banded or lined with different colored markings. If they are pale cream or white in color, then they are probably not viable and you have harvested them too early. You should wait until the end of flowering to harvest your seeds.
Your seeds will be mixed in with the bud and it can take quite a bit of time to separate them from their sticky calyx pods. Do not squeeze the calyx directly because you can damage the seed inside. Just tease the seed out from the calyx with your fingers. If you do not want the bud you can brush a seeded flowering branch against some fabric or a sieve to release the seeds from their respective calyx pods. It is easier to remove seeds from dry, cured bud than from freshly harvested plants.If you plan to use the seeds in more than two years time, store them in an airtight container and place this in a freezer. If you plan to use the seeds within the next two years, storing them in a standard film canister or similar container will work well. Keep this canister away from heat and direct light and do not let it get damp or your risk spoiling your seeds. Containers placed in the freezer should not be opened until you are ready to use them. Allow the seeds to thaw at room temperature for at least 12 hours before use.
