how to harvest seeds from male weed plant

Eliminate those male plants that flower too early, and rid yourself of those that autoflower. Plants that flower at unexpected times may have a higher chance of becoming intersex.

Allowing a male plant to grow to the stage where it produces cannabinoids will put your female plants at risk. If the male releases pollen and fertilises the female flowers, the plants will cease resin production and start producing seeds instead. Therefore, the risk far outweighs the benefits of smoking male plants, unless you have no other choice.

MALE CANNABIS PLANTS ENSURE A STRONG GENETIC LINE

There is a distinct difference in the type of fibres that male and female cannabis plants produce. Farmers normally separate them when they desire different plants for different uses.

If you have a rather large garden, you can potentially locate a dedicated space for your male plants. Keep them as far from your females as you can. You can further help reduce the risk of accidental pollination by planting sunflowers to create a natural barrier between your males and females. This allows you to cultivate incredible, smokable cannabis, without having to toss your male plants in fear of accidental pollination.

When you start breeding your own top-shelf bud, the male will contribute 50% of the genetic material. It just makes sense that you’d want to select the best male that you have as the donor.

Long-term storage requirements for seeds and pollen are similar. Both require cool, dark, dry, and oxygen-deprived environments for optimal preservation.

It’s important to continually practice germination testing to be sure your stored seeds haven’t lost all viability. To test this, periodically plant a seed and document its ability to germinate.

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.

Collecting Pollen

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.

Deseeding cannabis can be done by hand or machine. This process typically takes place after the plant has been dried for one to two weeks after harvest. This way, seeds will have reached their maximum maturity and plant material will be brittle enough to break apart with minimal effort.

A grower or breeder can also freeze the progress of a breeding project for months or years without losing any of the long, hard work. Endeavors such as phenotype hunting and maintaining desired mothers for breeding and cloning can all be saved for later through genetic preservation. This process is like backing up work on a hard drive.

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.

3.) Pollinate Buds

These are basic starting points for the home grower. I believe every person who grows cannabis needs to have this skill. Every strain goes away over time when people don’t make more seeds. Growers should know how to make their own seeds for preservation and sustainability. These skills can go a long way. The precursor to serious breeding is the basic technique of creating the seed.

Every pollinated branch should be labeled properly, your memory will not last as you think it will. A proper branch label includes dates, strain names, breeder/sources, and has the female listed first and male listed second. An example label looks like this: 4/20/2015 – Star Pupil (Mass Medical Strains) x Prayer Tower Sativa 9 (Bodhi Seeds) and the label should be kept with the seeds when they are finished. As years go by, you will be thankful for the dates and breeder information, which can escape our memory on occasion.

Best, however, is flowering the males in their own tent or space. With a carbon filter and negative pressure, and careful practices, you can avoid spreading pollen to unwanted spaces. The longer you flower a male out past its initial beginning release of pollen, the more of its flowering traits you will see! (More on best male plant selection below)
