How to produce cannabis seeds

When it comes to cannabis plants, feminized seeds are the most known ones. But do you know what auto and regular means?

1. Photoperiodic Cannabis

Photoperiodism isn’t unique to cannabis plants, many flowering plants sense changes in the length of night and day and use those changes as signals for when to flower.

Photoperiodic cannabis plants are just like that, they basically respond to changes in the light cycle.

As the night becomes longer at the beginning of autumn (in nature) or when you flip to 12/12 in a grow tent, the plant receives more darkness. This causes the plant to realize that its life cycle is coming to an end and they will start to flower (females) or produce pollen (males) in order to reproduce before winter.

Regular Photoperiodic Cannabis

Regular cannabis is photoperiodic cannabis that produces both male and female plants. They are called regular because they are produced the “natural way”: the pollen from the male plant pollinates the female, resulting in seeds.

Back in the day the only way to grow cannabis was with regular seeds, this way you would get half male and half females plants.

There is a big difference between male and female plants, while female grows buds, male plants will only grow pollen sacs.

In nature male cannabis’ pollen sacs will open to release pollen which will pollinate the female flowers, this way producing seeds.

But most growers that grow cannabis commercially or for their own consumption only want buds, allowing males to pollinate buds would ruin their harvest because pollination diminishes yield, so they’re mainly looking for female plants.

Feminized Photoperiodic Cannabis

To completely avoid accidental pollination and other problems related to male plants, feminized seeds were created.

Feminized seeds come from the cross of two female plants, one of them is stressed so it starts producing pollen sacs, which will fertilize the other female.

When you cultivate feminized seeds, the offspring will be only female plants. This takes out a lot of the unnecessary work that you can have when growing males and them not being able to use them.

Ever since the boom of feminized seeds back in 1998, growers have stopped buying regular seeds for quite a bit. Nowadays most seed banks don’t even sell regular seeds anymore.

With so much focus on feminized seeds, we can’t forget that regular seeds are vital for the creation of new strains.

2. Automatic Flowering Cannabis

You must already know that the characteristic that makes autoflowers an auto is they don’t need a different light cycle to enter the flowering stage.

Like their name says, autoflowers start flowering automatically depending on age, and unlike regular and feminized cannabis that need a change in the light cycle to start flowering. Autos don’t need anything else other than time to start producing buds.

But that trait didn’t come out of nowhere, it appeared as an adaptation to the environment.

You’ve probably heard of Cannabis Indica and Sativa…well, the autoflowering gene comes from Cannabis Ruderalis.

The Ruderalis species adapted to the extremely cold and harsh climates of Asia, Europe, and Russia. These regions have shorter warm seasons and colder temperatures.

Because of this, Ruderalis started mutating from a photoperiodic plant to an autoflowering plant, to guarantee its reproduction before the temperatures reached freezing levels.

T hanks to that adaptation, now we have autoflowers that take considerably less time from seed to harvest.

3. How To Make Your Own Seeds

Producing your own seeds is relatively easy if you have what it’s needed but that doesn’t mean the result will be a perfect strain. The good strains or “IBLs” that most seed banks sell are strains that have been developed for years and are far into the third or fourth generation.

IBL or stabilized strain means the offspring will have certain characteristics locked down. When you cross two strains for the first time the offspring can have infinite phenotypes and this is not good for commercializing.

Photoperiodic Regular Seeds

When we talk about cannabis, it’s easy to forget about male plants.

Everybody nowadays is used to the beautiful flowers we all love, but it’s important to remember that male cannabis plants are just as important as the females. Male cannabis plants produce pollen and are an essential element to the production of new cannabis plants.

This pollen is super important in breeding as it allows breeders to create crosses with genetics from different plants and create their own seeds. F or producing seeds all you need is pollen and buds.

Cannabis pollen is no different from regular pollen produced by other plants. It’s a fine powder that usually has a golden yellow color and is excreted from the pollen sac on male plants.

Collecting pollen is simple. You’ll know when its ready to be collected when the pollen sacks are open and you see pollen floating in the air and on the leaves near them.

When this happens, you can gently remove the sacs and store them in a ziplock bag, once you are ready to pollinate just release the pollen onto the buds. Another way is to simply agitate your male plants near the female plants, the pollen will stick to the buds.

Pollen is used in order to pollinate female plants and create seeds. In nature, female plants get pollinated by the wind which carries the male pollen.

Cannabis seeds develop in the buds about 4-6 weeks after pollination, you will see the calyxes start to round up from the seeds being inside them.

P ollinated buds look quite different from regular buds. They usually don’t have as many trichomes and are usually smaller and a lot more swollen.

4 weeks after pollination, you can start checking the buds to see if the seeds are ready for harvest by picking a couple of seeds from the bud.

M ature seeds will have a hard shell and be a dark brown color, they might also have some stripes on the outer shell.

Photoperiodic Feminized Seeds

Normally, a male cannabis plant has to pollinate a female plant to produce seeds. The resulting regular seeds will contain about half male and half female seeds.

The way feminized seeds are produced is the same but instead of collecting the pollen from a male, breeders will stress or spray flowers with colloidal silver, for example. This process forces the female plants to become a hermaphrodite and starts producing pollen sacs.

Hermaphrodite plants are females that are halfway turned into males, this means she has both male (pollen sacs) and female (buds) parts.

By picking out the pollen sacs and using a reverted plant’s pollen to pollinate a female plant, you will have only female genes as there is no “father”, this way you get feminized seeds, meaning the offspring will be 100% female plants.

Feminized and Regular Autoflowering Seeds

• Regular Autoflowering Seeds

Usually, you can find regular and feminized seeds, and this applies to autoflowering seeds also. This means you can find male and female autoflowers, depending on the type of seed you buy (regular = 50% male and 50% female, feminized = 100% female).

Unfortunately the high increase in the production of feminized seeds affected automatic seeds also. Although it’s not common to find regular auto seeds nowadays, they do exist.

For producing regular autoflowering seeds all you need is male pollen and female buds, just like for regular photoperiodic cannabis. The process is basically the same, collect the pollen from the male and spread it on the buds, this will result in regular autoflowering seeds.

• Feminized Autoflowering Seeds

The process of producing feminized autoflowering seeds is almost the same, the only difference is you will need two female autos instead of one male and one female. You will have to make one of your female autos produce pollen, either by stressing her out or spraying with colloidal silver and pollinating the other female. This will result in a 100% female automatic offspring.

4. In Conclusion

Even though it is fairly easy to produce seeds, we recommend having a bit of experience before trying it.

We recommend easy-to-grow strains like Zkittlez Auto to start acquiring experience before going into breeding.

What’s The Best Way to Make Autoflowering Seeds?

I’m really fascinated with auto-flowering plants and want to
make my own seed collection. the only seeds I can seem to
find online are all feminized. does anyone know where to buy
quality normal auto flowering seeds?

And if that isn’t available whats the better strategy.

#1. use colloidal silver during the flowering stage to force my
females to create pollen (and thus turn into hermies?).

#2. try to cross them with say . BIG BUD. strain. and if i do
that, is it right that only 1 out of 4 of the new seeds would then
be auto flowering + big bud?

Thanks for your advice!

Ignore this guy. Anyone who thinks auto’s suck just can’t grow them well.

The best way to get autoflowering seeds is to buy either a strain that is regular (male and female seeds), or a fem strain and use CS or some other reversing agent to make fem seeds.

If you cross an auto with a regular photoperiod plant like big bud, NONE of the offspring in the first generation will be autoflowers. If you take two siblings from the first generation and breed them together, one fourth of THOSE offspring (f2 second generation) will be autoflowering.

The autoflower gene is recessive. When you cross a dominant gene with a recessive one, the recessive one gets hidden in the f1 generation.

AA (photo) x aa (auto) = Aa (photo het. for auto)

Cross those offspring, and you’ll get some autoflowers.

No. It DOES matter that the autoflowering trait is recessive, and none of the f1’s will be autoflowering, as a result. That’s what recessive means. That when paired up with a dominant trait (photoperiod) it will not show. A plant can be a carrier of the auto trait, without autoflowering, and that’s exactly what all of the f1’s will be.

Also, you don’t get a variety of different plants in an f1 generation. They are all uniform, with only the dominant traits from each parent showing. That’s what gives them hybrid vigor. Once you move on to f2+, recessive genes start pairing up again, and the hybrid vigor is lost. However, in order to create plants that produce stable, predictable offspring, you need to inbreed several generations.
