Marijuana (Cannabis)

How To Produce Marijuana Seeds


Produce your own marijuana seeds by selectively pollinating one or more flowers on a female plant, rather than the entire plant, with pollen from a male plant. When the plant is harvested, a single small flower that was pollinated will contain at least ten seeds.

By producing your own seeds, you will always have a steady supply to start new plants from, trade with other growers you know, or sell. You will not have to pay for seeds that can be expensive and/or hard to acquire.

Pollen And Brush On Plate Seeds should be stored in a cool, dark, dry environment to maximize their life span. A fridge with low humidity levels is a good place for seed storage.


Procedure

The male and female marijuana plants have to be the same strain unless you are experienced with breeding, and working on creating new strains. You can not just cross two different strains, the resulting seeds will be genetically unstable.

Once the sex of the plants is apparent, male plants should be removed from the area the female plants are growing in, or they will pollinate all the female flowers, also called buds, in the grow room.Flowering Female Marijuana Plant That means you will need 2 grow areas that are separated far enough away from each other so there is no chance of male pollen accidentally reaching female plants.

Unless you need thousands of seeds, it is better to pollinate a limited number of female flowers. Marijuana from buds that have been pollinated will be less potent than marijuana from buds that have not been pollinated, so it is in your best interest to keep the number of flowers producing seed to a minimum.

By selectively pollinating a limited number of female marijuana flowers, the potency of the remainder of the crop won't suffer.

After a few weeks flowering, the pollen sacks on the male plant will open and release pollen. Pollen can be seen on leaves that are under sacks that have opened.

Flowering Male Marijuana Plant

Collect some pollen by brushing the pollen sacks on a flowering male plant while holding a clean sterilized plate underneath. The plate will catch some of the pollen as it falls from the pollen sacks.

After collecting the pollen, bring it to the area where the females are growing. Turn all fans off and make sure no breeze will blow the pollen into the air. If necessary, cover the plate with a bowl or something that will serve a similar purpose.

Choose one or more flowers on a female plant for pollinating. It is best to choose small flowers that are lower down on the plant. Keep in mind that each small flower you pollinate will produce at least 10-50 seeds.

Pollinating smaller flowers is done so the larger buds are not affected while the smaller flowers produce seed. It does not mean that the seeds will be of lesser quality, just that the premium marijuana isn't sacrificed on seed production when lower quality flowers can serve the purpose just as well.

Brushing Pollen Onto Female Marijuana Flower

When you have decided which flowers to pollinate, load some pollen on your paintbrush by pressing the bristles into the pollen that you've collected on the plate.

Brush all over the flower very gently so that you've covered every bit of the flower that can be accessed by the brush. Repeat this process a few times, spending 1-2 minutes per flower. Add more pollen to the paintbrush if you think it necessary.

Do this gently as if you were painting the flower. You do not want any pollen getting in the air where it could land on other flowers not intended to produce seed. Turn fans off during this procedure, and if possible leave them off for a day or two after.

If you require fans that will blow on pollinated flowers, then it is best to cover them for 2-4 days with a plastic baggie, coarse cheesecloth, or something else that will cover the flowers, while letting some light through, and prevent the pollen from being blown off and into the air.

When you remove the covering, do it just after the fans turn off for the night. This is so any pollen disturbed won't be blown onto other flowers. Also the fans will be off for a few hours after, so any pollen you disturb and get in the air will have a chance to settle, away from other flowers.

After you have covered as much of the flower as possible, you can stop, or repeat the process on another flower. Do this until all the flowers you want to pollinate are done.Twist Tie On Pollinated Flower To Mark It

When you finish doing that, mark the flowers that have been pollinated with a twist tie, red twist ties are usually very easy to see, or something else that makes the pollinated flowers easy for you to identify.

When harvest time comes, it is a simple task to find and keep track of the pollinated flowers. Dry them with the rest of the crop, and do not use heat to speed drying or you could kill the seed.

When the bud is dry enough you can break it up and remove any seeds. To grow plants from seed, the process is started by initiating germination. Instructions for germinating marijuana seed is located here.


Step By Step

A) Turn all fans off, make sure there is no breeze.
B) Brush pollen sacks on a flowering male plant.
C) Hold a plate underneath to collect pollen that falls.
D) Transport pollen to female plants.
E) Choose female flower(s) for pollinating.
F) Load some pollen on an artist paintbrush.
G) Brush pollen all over female flower gently.
H) Try to cover every bit of the flower you can.
I) Mark the flowers that have been pollinated.
J) Gather seeds after harvesting and drying the crop.
K) Store seeds in cool, dark, dry environment.
L) If possible, keep between 40-60°F/4-15°C.


List Of Materials
plate
twist ties
artist paint brush
male marijuana plant
female marijuana plant
clean cloth or paper towels
hydrogen peroxide or rubbing alcohol


Notes

1 --- Cleanliness is very important. The paint brush must be restricted to seed production only. Sterilize the plate and brush with rubbing alcohol or hydrogen peroxide. Put it on a cloth or paper towel and wipe the entire plate and brush handle.

Dip the brush bristles in your chosen sterilization liquid and wait for them to dry completely before working. When you are ready to start, wear clean clothes and put on some clean latex gloves, or wash your hands thoroughly with soap and hot water.

2 --- Try to select the best male and female plants you have available when producing marijuana seed. Do not include unhealthy or scrawny specimens just because they are there.

3 --- Dry the flowers that have been pollinated with the rest of the crop they came from. When they have dried fully, gather the seeds together so they can be stored until they are needed.

4 --- For long term storage, dry seed can be housed in plastic or paper. Some people have reasons for choosing one over the other.

5 --- Warm temperatures and high humidity will reduce the lifespan of marijuana seed. Stored in an area that is dark and dry with temperatures of 60°F/16°C or more, they will remain viable for up to 1 year.

6 --- Stored at temperatures between 40-60°F/4-15°C in a dark and dry area like a fridge, marijuana seed will remain viable for at least 1 year, and up to 3 years, after the plant they were produced by has been harvested.

As a seed ages, it loses vitality. This means seed that is too old will take longer to germinate, and the resulting plant will grow slower and be less resistant to disease and other things that a healthy plant can fight off.

When germinating older seed to produce a crop with, choose the seeds that germinate quickest and exclude any seeds that are slow to germinate or look unhealthy after germinating.
