how long does cannabis pollen last

How long does pollen live


The last grow resulted in a couple males and few hermies busting their balls in the growroom (don’t want a rerun) so I’m curious about the pollen that would have been sucked into the canfan scrubber that needs to be reused..

This is a completely different/new room this go around but I hate to buy another filter you know.

How long does pollen actually live?

Is there anyway to kill it in the filter? (carbon)
Obviously I can’t put water in it soooooooooooo .

As always any help is appreciated welcomed and thanks in advance!

Living dead girl

Pollen from cannabis tends to be rather shortlived (weeks to months, though I know folks who’ve managed to keep it viable for a couple of years) unless special precautions are taken to ensure it never comes into contact with moisture. I’ve learned that even a dewy morning can mean very little of the pollen you apply will take and set seed.

If your goal is to ensure whatever pollen may remain is dead, best bet is to spritz the girls. I would suggest raising humidity to a higher level, but I cannot state unequivocally that this would do the trick the way I know contact with water, even very fine droplets, will.


Thanks to everyone for the interest and help.

Hi SeaMaiden! (and thanks)

Since this is a new/different location/setup altogether the main concern is with the canfan/scubber spitting out remaining pollen from the old room into the new room. ISTM that the simple act of the violence of the turbulance, etc and being banged around in the fan/charcoal, etc should hasten the end of life of the pollen. (hopefully)

We definitely don’t want any males/pollination this time so wondering if there is anything we can do to hasten and kill the remaining pollen (if any) in the canfan without the additional expense of buying another.

Maybe sit trays of water around it to circulate through it or something possibly – this just sits on the floor with a fan on top for recirculation/scrubbing.

What about misting/soaking the outside of it every hour or so with water maybe. Think the moisture would kill it?

Was hoping possibly someone had experience in this particular situation maybe.

We’re a little over two weeks in from seeds so we have some time to ensure the kill before it would be critical.

As always any help is appreciated and welcomed and thanks in advance!

How Long Does Cannabis Pollen Last When Stored?

Cannabis pollen is vital to the cultivation process. As with other types of plants, pollen from cannabis plants is a really big part of the ‘circle of life.’

Male plants may not be desirable from a consumption standpoint, however, they are very important in the process of keeping a desirable strain going.

The pollen from male plants, when applied to a female plant at a certain time in the growth cycle, will result in the female plant producing seeds.

Those seeds can then be used to grow new female plants that do not have seeds and thus keep the strain going for consumers and patients to enjoy.

With that being said, how long does cannabis pollen last in storage?

Canadian Government-Funded Study Results are Encouraging

Researchers in Canada explored various ways to store cannabis pollen to see which method yielded the best results from a preservation standpoint.

The study was partially funded by the Candian government. Canada is one of only two countries that have legalized cannabis for adult use and is home to the most robust adult-use cannabis industry on earth.

According to the researchers, they “developed a long-term storage method which includes pollen combination with baked whole wheat flower and desiccation under vacuum for cryopreservation.”

After assessing the efficiency of the storage method, researchers concluded that, “By using this method, we were able to maintain germination viability in liquid nitrogen after 4 months, suggesting potentially indefinite preservation of cannabis pollen.”

During the course of the study researchers also “deciphered the bicellular nature of cannabis pollen using DAPI staining,” and “found pollen collected from different principal growth stages exhibits different longevity.”

A Game Changer for Cannabis Genetic Storage?

For some cannabis cultivators, storing cannabis pollen is not really necessary because they can perpetually cross-pollinate plants without interruption.

However, for other cannabis cultivators, it is necessary to store cannabis pollen for future use.

That could be due to a number of factors, including being part of a precautionary strategy should there be issues with a cultivation facility’s genetics. Once the genetics are lost, it can be nearly impossible to get them back.

Long-term storage of cannabis pollen is particularly important for the international cannabis industry, where pollen is needed from far away places for various reasons.

Being able to store cannabis long-term provides a great level of flexibility for cannabis cultivators around the world.

It is also good news for consumers that really like a particular cannabis genetic because long-term storage will help ensure that those genetics are around for years to come.

Canadian researchers are finding new and innovative ways to store pollen. That's good news for cannabis connoisseurs and their favorite cultivars.
