how to get seeds from female cannabis plants without pollination

Fortunately, preserving genetics for long-term storage is easy and will save time, money, and space in the long run. Through seed and pollen collection, you can hang onto those genetics that you can’t fully get rid of and safely store them for future use.

Cannabis is for the most part dioecious, meaning that the male and female reproductive organs exist on two separate plants (although hermaphroditic plants do occur). It is also a wind-pollinated plant, so pollen must be transferred from a male stamen to a female pistil via the air in order for pollination to occur and seeds to form.

The Benefits of Long-Term Storage

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.

When storing seeds, place them in an air-sealed container that doesn’t have any light leaks. Film canisters, medicine bottles (non-translucent), and any sealable storage jar will work fine. The idea is to reduce the amount of oxygen present in the storage space as much as possible. You can also add uncooked rice to the storage container, which acts as an absorbent, to reduce moisture content.

Make sure that your isolation chamber does not contain any female plants that you do not wish to breed with. This will ensure the prevention of unwanted cross-pollination. However, if more than one female cannabis plant must mature within the same space, implementing the following selective pollination technique (which involves using plastic baggies and some ties to protect the pollinated colas) should still adequately protect your room.

This application process should repeat 1-3 times over the course of a week or two. After the fourth week of bloom, you may suspend your process. Should you need to reintroduce your pollenated female back into a room with other maturing female plants, you can rinse the plant down with clean water immediately following pollination to remove any excess pollen. This isn’t one hundred percent fail-proof, but when done carefully and correctly it can encourage the plant to breathe a little better.

What Are the Limitations of Breeding for Home Growers?

Keep the desired male plant in isolation throughout the pollen collection process, then terminate the male to be safe. By using a small paintbrush, you can carefully collect pollen into a plastic bag or glass jar.

On the other hand, those who wish to carry seed stock through to the next season will find breeding to be a sustainable alternative to keep those genetics around. Not every grower can afford to go back to the nursery or seed company and purchase new genetics between every season. After all, in most states the cost of a single clone can exceed $20, while a dozen cannabis seeds could easily cost $100 or more. For many micro-budget home growers, breeding is the only way to keep genetics around.

4. Harvest and Collect Seeds

this is how some seeds companies produce female seeds, by over maturing a plant until it produces pollen

i have noticed myself lower popcorn shitty buds are more likely to throw a few seeds
i think this could be because these lower buds seem to mature too fast because they get less light, by the time you harvest
these lower buds can be over mature full of brown pistils and some seeds

i think many people do not grow enough plants or mature them long enough to notice that more often than not, a plant/strain will make a seed or two
this is normal

The plants are very healthy with no problems.
