Outdoors, pollen can be viable for a week or two under normal conditions. However, when frozen and sealed, it can last up to a year and even longer. Pollen is more unstable than seeds and, even under the most optimal conditions, is not expected to have such a long lifespan. Sufficient moisture was removed from the cannabis pollen before it was combined with baked whole wheat flour and stored in liquid nitrogen.
By removing pollen from the mixture, the researchers applied it to female flowering plants, resulting in successful seed formation in all test subjects. Viable germination lasted 4 months, implying that it is possible to conserve cannabis pollen indefinitely. This is invaluable for maintaining a large collection of genetics. Once dry, the pollen will last a few years in the freezer.
Keep it cool, dry and dark for maximum longevity. Avoid opening the cannabis pollen container unless necessary. As pollen begins to reach the end of its lifespan, you'll notice that it becomes more lumpy and isn't as easy to apply as before. Once all my pollen is collected and dried, I pour it into small plastic containers and add it with some dry organic rice as a desiccant.
It is important to use organic rice to ensure that there are no chemical residues from pesticides or herbicides that can kill pollen. Each container is labeled and then placed in the freezer for long-term storage. You can store pollen in the refrigerator if you want, but keep in mind that temperature fluctuations caused by frequent opening and closing of the refrigerator can reduce the long-term viability of pollen. In addition to using cannabis pollen to produce photoperiodic feminized seeds, it can also be used to make autoflowering seeds.
For most growers, cannabis pollen is avoided like the plague; its only important purpose is to produce seedless (seedless cannabis buds). In the 1990s, Henk van Dalen, the founder of Dutch Passion, announced the creation of cannabis pollen that would produce seeds that only grew to become female cannabis plants. For them, storing cannabis pollen in the freezer may be a more convenient option than trying to conserve a room full of cuttings. It is sometimes used within a growing community to allow people to produce their own cannabis seeds from their favorite cannabis genetics.
Henk's creation of female cannabis pollen changed cannabis seed production forever and put Dutch Passion on the map. Cannabis pollen, crucial for seed generation, is the powdery, dusty and typically yellowish material produced by male cannabis plants or flowers Masculine hermaphroditic seed-producing plants. Often, the goal is to use cannabis pollen to fully pollinate a female plant, with the goal of producing cannabis seeds. However, all you need is a little time, patience and simple equipment, and you could build up reserves of your favorite cannabis genetics in no time.
Diluting 1 part of cannabis pollen with 4 parts of dry, finely ground powder may not appeal to old school purist breeders, but for less experienced cannabis growers it's still an option. I will cite the study and explain why this development is so important for cannabis breeders and for the entire cannabis industry. The best cannabis seed suppliers and breeders can also create extensive cannabis pollen archives from the best individual specimens of the best varieties. In a new study, funded in part by the Canadian government, researchers have developed a method for storing cannabis pollen for extended periods.
Anyone in an area where growing cannabis is not legal must keep cannabis seeds as collectible souvenirs. Whether cannabis fans are trying their green thumbs as a hobby, to reduce their monthly cannabis budget, or to provide stable access to medicinal buds, the amateur grower has a lot to learn. .
