Official Seed Harvest, Storing, Curing, ect. Thread

I know many people come here to learn so I decided to start this thread for some of those with experience to share with those looking for knowledge. I understand the basics of pollination, and there seem to be quit a few threads on that issue, but haven't found a thread on here which details the process after. Let alone specifics on things like storage or keeping viability up over the years. Tricks of the trade, techniques, preferences, suggestions, and more are welcome.

So for those who have had experience or if you just have any questions, then put them here.

I would like to start this also by opening a discussion on how you, or those you know, dry out seeds. I've done my research and found that many believe about a month or so of drying is necessary to increases germination rates, but what else helps?

Looking very forward to hearing back from any and all. Best wishes and karma all around.

Moisture

This is a great idea Unknown! If you don’t mind I’ll help?

Here some of my fumblings. By the way I haven’t looked closely at early germination because I’ve have had seeds drop & germinate on their own. I always test the germination of each seed run but have never logged how many days from harvest. I will now.
As to storage, I have found that two year old seeds have the highest ratios of all my germination trials. Though I do not know why this is so for me.
The SINLGE most important thing I have found, to my detriment, is moisture! If you seal your seeds and ANY condensation forms you’ve degraded their chances! Everyone says to use something to I think slow drying as in curing, increases the chance of moisture damage. So I keep my seeded flowers drying much faster then my medicine. I often dry them in small brown bags, easy to write on.

Thanks nobull I never could ever mind any of your help my good friend. That's very interesting that your best rates are that far along. I only pollinated one or two small bottom branches this time around and have them hanging in darkness like I would any other. I'll probably seed through them sooner than later then.

I was also wondering (and this isn't directed at you nobull but of course I'll always have an open ear for you) after the separation I can store them, any container better than the other? Like how glass is better than plastics for flowers. Also at one point is it okay to put them in the fridge for extended storage?

Last but not least:
I was searching desiccants to possibly add to the seeds and came across this hope it helps others aswell.

^^Basically the same as ezozo's and others...

you can but silica gel in 50 gram bags (~5$) the balls are blue when they dry and getting pink when the soaked.
you can re-used them - let them dry on the oven/micro for fer minuts and they will tern blue again.

here is the pack

here is how I put them in a film box

then I every day type on some male flowers in to the box.

then after few days I have

look at the sillica balls turning pink the I add some more.
I keep them in the refrigerator till I need to pollinated the ladys and if I need to send them or to save them for longer time -

I put the pollen in a small bag will new sillica gel and freez them after they are dry

PS - my max time that I try to use saved pollen was 7 months with success but not 100%

I live in a humid tropical weather. A few months earlier I harvested some seeds and stored them too early in a zip bag, and after a couple of days I saw some small fuzz growing on some of them (mold mycelium). I immediately removed them from their zip and put them inside a paper enveloppe for a couple of weeks, checking and aerating/shaking everyday. The mold disappeared and they germed fine, but now I always let freshly harvested seeds "cure" in a paper enveloppe for at least 2-4 weeks before bagging them, shaking the enveloppe a few times a week. Never seen any mold since that, and germ rates are great (90%+).
It seems paper allows breathing and buffers humidity changes, I'm sticking with it for the moment.

glad you're getting informed thus far...

One more question...

I currently have the pollinated branches hanging at what point (or does it matter) do you de seed the crop. I chopped my branches this last friday and I started deseeding them last night. Some of them glistened, which I assumed was the thc that they rubbed against, but I guess it could be moisture. Regardless I categorized them and placed the seeds spread out in a coffee filter to air dry some more in darkness.

I was planning on a little less than a month dry, then bag them up and store them. After 6 months I was planning on throwing them in the fridge. Is this okay to do or does anyone have any insight or better way?

Regardless nobull, tropic, and marlo thanks for stopping in and feel free to add any input.

Happy harvesting...

Wait till the buds are dry before deseeding, rub all the stuff from the outside of them and let cure in between two paper towels or two sheets of newsprint for another week or so, then package with silica gel in airtight containers. If you aren't going to germ them for a few months stick them in the fridge, but I suggest letting them rest in the container for another month before you try them out... it seems to help the germ rate.

I gotta say that you are more than right. I did a search and could not find shit on seed harvesting... I'll take plenty of pictures and document my next run in this thread and invite you and UP to do the same...

That's what really makes this place such a pleasure... searchable reliable information!!

Time improves techniques, but some of us old farts are too hardheaded to change what worked in the ‘Olden days’.

With this disclaimer I’ll take a toke & start a ramble!

I do not worry about cleaning my seeded branches until EVERYTHING else is cleaned cured & put away. Then I take the well tagged branch (I use hanging tags when I pollinate & document Male, Female, Dates pollinated & ANYTHING else that matters,keeping tag on all the way) & hand roll the whole thing to fine shake, removing all stems. I start on a Kief screen (why waste anything) then move to a smooth tray (NOW; they use grading screens) for rolling the seeds away from the chaff. I clean the seeds two or three times, taking out all odd shaped & off color beans.

At this point (depending on the size of the run) I lightly sandpaper 10 to 100 seeds & test the germination rate (keeping some of the most vigorous to pot up). Ten plants can tell me that the cross is growing consistent or if it is mostly sports.

I think it is more important to have viable seeds as so many times I’ve bought seeds from ‘BIG NAMES’ only to not have them germinate or have only one or two pop. If I sell seeds that do not do what you want, I can trade you some thing else or we can talk it out. If they don’t grow, you’re PISSED!

By now I’m not worried about how dry they are & I bag them in ‘Snack’ baggies, writing the info on the bag (tag goes in bag also). I keep my seeds in a box (see Photos) & keep the box where the temperature changes very slowly (NOW; in refer or some kind of transformer golly dam-et) (probably much better, but moving them seams troublesome). It seams to me, that the most harmful thing to do to a seed (besides moisture) is let it think winter, summer, spring or fall have been around. Cold to warm is a major trigger to make a seed want to grow & if it sees that too much; the week seeds will give up & never grow into a strong phenotype, if at all.

Well I’ve ranted too much for one time. I’ll do the photos now, those that know me will recognize the box.

I didn't have these two photos uploaded.

Here are the seeds I Bought last year ( U can see I like 'Nivarna', lots of stable stock)




This next one showes how these high rollers now send their $$ wears. They started with hard coin protectors, then baggies, now this!!



A paece of plactic cardboard & Q-tips to hold them in! Next year 'Scotch Tape'!!!
