Pollen Drying and Storing

image

I put the pollen in a vial, leave it open, and close the jar with alot of dessicant. At least a few days, check on it, never had it clump like this. Then close up the vial, close the jar, and into the freezer.

Just let it come to room temp completely closed, not in a very hot room.

it’s all about a clean collection for me, in a dry room.

Every time I’ve added flour to the mix it hasn’t worked. Even stored in vac with desiccant
It just seems like another thing to somehow go wrong in a situation that’s already pitted against long term storage haha

I toast the flour (thinly spread out) on a tray in an oven, 200F for 40 min. to dry it out.
I mix 1:5 (pollen/flour). That’s been working… (so far :grin:)

I was pretty surprised when I air dried some pollen, threw it in the fridge and it molded, so I would try the flour method . Freezer may be better than fridge, no clue.

The paper I have that recommended it did not explain why it worked… just that it did and was required…

…That irks me somewhat…

Anyway, the drying box worked for me, I’ve had a couple reports of sucess for folks that got some.

i’ll share my method since i have a small pile left over to deal with anyway.


You can see there is more pollen than flour on the plate, it’ all you need for bulk storage. If you wanted to you could cut this 1:8 but then you gotta store 8 vials instead of 1…and when you deal with very large amounts of cannabis oriented stuff (seeds,nugs,pollen) you run out of space fast and these things suddenly come to the forefront.
the oven knob is barely past the Off, just enough to turn it on. They usually have a warmer setting, to keep food warm. If you have to, you can keep the door slightly open to control the temp. What we care most about here is the humidity…we gotta drive all moisture out…I even put my vials in there, that’s good science yo.

RH dropping, temps rising. What we want is to hit 20% RH.

Temps aren’t super critical…remem it’s the moisture we care about. But a word on temps, these things evolved when earth was very different than it is today. Those pollen grains can take a bit of heat, but there is an upper limit before you start damaging them. I personally put the upper limit of heat exposure for pollen around 135-155f sustained. BUT!! you will never go anywhere near that right? cuz this is all we need 20% RH

hold this for a tick of time that’s comparable to the amount of pollen and flour in the oven. If you put a large pile in there, it would take longer to drive moisture out. This tiny pile is done in 2-3mins once 20% is reached. Then just rapidly remove, mix, and bottle in vessel of your choice. It’s all about the moisture.

I just collected some pollen and put it in sealable plastic bags (the size of a business card). I then stuck it in a container with a big bag of descant. I was going to stick it in the fridge for now, may want to save one of them long term. I’ll think of adding flour, white or whole wheat? :stuck_out_tongue_winking_eye:) I use Dollar Store artist paint brushes to collect and use to put the pollen on the plants.

hi @Gpaw . I just fell into religion.

my plan is to dig up one of two males and collect pollen from it for next year. will have to remove the unnecessary male.
should get (wild1 x wild2) x UEL and UEL f4

@Cartwright @highminwin @Mudballs thanks, now I’m charged to win!

I like the idea of using DE for cutting pollen. I wonder if the microscopic sharp edges of DE would adversely effect the viability of the pollen…?

either RH was too high in the room, or you didnt dry long enough. I’ve put pollen in a sealed tote (rubber ring / locking handles) with dessicant packs to bring RH down to below 20%. If your ambient was 50% or higher when drying, it didnt dry enough. My first batch molded too.

I take fresh male flowers that just opened, put them inside a small dish(open) inside of a pelican case with a large silica gel pack. Within 2 days rh is 20% or below I knock all the pollen out of the flower pod and put the dish back into the pelican case for another 2 days. After rh is back to under 20% it goes into the fridge sealed and so far has been good for over a year. I have to do it that way as rh here is always 90% or above.

Thats a good idea… I shoulda thought of that as I have a few pelican cases here for dive cameras… Hmmm

keep in mind diatomaceous earth is a severe respiratory hazard, including food grade DE.
I wouldn’t want to be dusting it around like pollen.

I remember once putting emptying a bag of buds on my coffee table was a tad damp, I wanted to air dry it a bit, I went to sleep, woke up I think it weights like 2 more points. lol

somebody drying pollen in a pan with paper and at minimum power?? And what about drying absorber in a pan. Sure riсe is a good like absorber. Need try.

What’s your technique for saving pollen. I have not had good luck.

@PhilCuisine had some Pollen that was viable after 15 years.He may have a tip or two …I know he likes to store in the refrigerator and uses tinfoil not too certain after that.I got some pollen from Doug and I took the dime baggie of pollen and I stuck it with two desiccant packs inside one of those scent proof Mylar bags that hold like an eighth then I stuck that in a jar filled with rice then put that in the freezer.Will see if it worked very soon.

I have been pulling the flowers off when they open and the pollen bananas are dangling you can see the pollen and it’s kind of sparkley I popp those in a container with desiccant packets in it with a paper towel a little Tupperware container.I wait a couple days picking flowers as I go then when I get a big enough pile I take a dinner plate and I use a screen pan lid to drop the dried flowers on.I agitate them a bit not too rough to push plant material into the pollen.I collect it with a silicone spatula and put it in one of those micro vials back into the desiccant Tupperware and I leave the lid open in the vial to dry out the pollen in the tube before I close it up.I periodically rotate said vial once the pollen flows like sand in an hour glass your good to close it up.If your pollen is all clumpy you fucked up and there’s moisture in it.I put all my vials labeled inside a mini thermos in my refrigerator that I plan on using soon so no one opening up the fridge jacks up the humidity that’s what messes up pollen the worst.My long term pollen is in the freezer

What about just simply collecting the pollen, letting it sit and dry for a few hours, put it into those little plastic vials and throwing it straight into the freezer? Just throwing it out there, I’ve never been tried collecting and storing before so all this is completely new to me

For medium or long term storage you need to really dry out the pollen.

This worked.

I’ve got some ‘tucked away’ to test at the 1 year mark.
