A female cannabis plant that has received pollen from a male will produce many seeds over the course of its maturation cycle. Upon senescence, when the female plant is fully mature and ready for harvest, its seeds will be ready for stratification and collection.
To tell if a seed is mature, take a look at its shape and color. Premature seeds will be small and light in color, taking on a beige hue. Fully mature cannabis seeds are more full in shape and size and have a much darker brown hue, sometimes accented by black tiger stripes.
How to Collect Seeds
Moisture is a death sentence for pollen viability. Because of this, many breeders opt to mix flour into their pollen at a ratio of 4:1 (flour to pollen) when storing it long-term. This additional step will help keep pollen dry for a longer period of time.
To release the seeds, simply break up the dried buds over a screen and they will fall out. You can release the seeds en masse by rubbing the flower between your fingers and lightly breaking it apart.
You can expect cannabis seeds that have been sealed and properly stored to last for several years, and in many cases, longer. Seeds may be dormant, but they are still alive. Over enough time, they will lose their viability.
This is part of the reason why people generally prefer to buy their seeds from a reputable seed seller, due to the fact that you are more likely to know what you’re getting.
Contrary to what most people think, what you’re smoking isn’t actually the rolled up or dried leaves of the Cannabis Sativa plant. You’re actually smoking small flower buds.
What happens to the seeds is that they are tricked into thinking they have been successfully buried into soil.
#2 Seed Survivability – It Might Be Too Dry!
Lay your lovely brown seeds on the paper towel, making sure to give them as much room as possible.
Cover it with another piece of wet paper towel and cover the whole thing with another plate of equal size. This should make a handy little clam-shaped house for your germinating seeds.
Enjoy harvesting your new marijuana and keep an eye out for new seeds in your freshly harvested buds.
Given some time, you might find yourselves planting the great-granddaughter of your first seed!
You might be tempted to jump right in and start growing your new seeds. Not so fast though, you’ve got to pick the right seeds.
Before you can do any kind of planting of your seed, you first need to germinate it.
Pollen is fine powder that usually has a golden yellow colour. It consists of tiny microscopic grains excreted from the pollen sac on male plants.
You can then move your pollinated female plant out of the room and back into another grow environment. Just make sure to keep both your male and pollinated female as far away as possible from the females you don’t want to pollinate.
WHAT IS CANNABIS POLLEN?
As we mentioned earlier, cannabis pollen is typically used by breeders and expert growers to create new strains or seeds. They do this by harvesting pollen from their male plants and then applying it to female plants that are about 2-3 weeks into their flowering cycle.
Pollinated buds look quite different to regular sinsemilla. They usually don’t have as many rich trichomes and don’t form into large colas. Instead, they’re usually smaller and a lot more bulbous.
Cannabis pollen is no different from regular pollen produced by other plants.
