dc's Seed Labeling and Storage Tips

Got a question today about seed storage and thought it would make for a helpful thread. If you've ever had questions about what to do with your seeds once you've made them by breeding two plants, this should answer some of them.


UserQuestion: said:
I got a ton of seeds! Should seeds be kept in refrigerator until germination? If so with lid on or off?


Let the seeds dry and cure naturally in the buds, or at least leave them out in a dark place so that they dry really well. Once they're bone dry, just put them into film canisters, jars, or ziplock baggies labeled with what the contents are (this is what I do, I use the little jewelry bags).

I actually write the strain is (Female x Male), whether it's mostly indica or sativa, tall or short, yield description (low, med, high), and the date that the seeds were done so that you'll know exactly how old they are when you go to use them years from now. Once you have all your beans separated and labeled, put a couple of grains of dry, uncooked rice in each baggie with the seeds. This is a desiccant, and will absorb any moisture that might get into the bag preserving the seeds. Gently squeeze out all the air, seal up the bags with the rice grains in them, and then put all of those individual baggies of seeds into one tight-sealing jar with one of those silica packets, which of course is another form of desiccant. Seal the jar up and then store in a completely dark, cool area.

They do say that storing them in the freezer will help them to retain their viability longer, but I can't stop thinking that the moisture in the freezer would get into the seeds and be bad for them. I mean, all our meat and everything we put in the freezer ends up getting freezer-burnt if you leave it in there long enough (like a year), so I don't see how this wouldn't affect seeds as well. You always end up seeing that crystallized condensation on the INSIDE of the meat packaging and stuff. Moisture is a seeds worst enemy in terms of storage. The problems of maintaining seed germination increase with seed moisture content. At 8-9% moisture level insects become active and reproductive. At 12-14% moisture fungi can grow on and in seeds. At 18-20% internal heating may occur, which speeds up the process of decay. And last at 40-60% moisture seeds start to germinate. So like I say, I keep mine in the dark in a room in my house with low to average humidity. I've popped seeds that were years old and still had almost 100% germ rates, so the dark, dry room method can't be all that bad.

Happy growing!

Most if not all seedbanks store seeds in refridgerators.

They also have a lot more seeds to keep, and they prob have a non-conventional piece of equipment that does a lot better than the average run-of-the-mill, generic GE apartment fridge.

There are new refrigerators that have extremely low relative humidity inside of them, but I don't think most people are going to have this.

My main thing is, any gain by keeping the seeds in a cooler temperature (which does extend viability) via a freezer or refrigerator can easily and quickly be negated by the addition of moisture (which of course speeds up the process of decay).

Seed storage life is doubled for each 1% decrease in moisture content.

Seed storage life is doubled for each 5 degree C reduction in storage temperature.

For me, the easier of the two is to just keep the humidity non-existent. I never have to worry about moisture. Sometimes I like to leave well-enough alone. But yes if one could maintain the lack of humidity in a chilled environment, then that would be optimal overall. Dry ice anyone? :mrgreen:

If they are in ziplock bags how does any extra moisture get in even if you have the worst fridge in the world?

Well I don't know Mr. Speedy, how does it get inside of other baggies in the freezer with other food items in them? Why does anything in the freezer go bad? Why is it not all perfectly cryogenic-ally frozen like the day it was put in there?

Dude, just because you don't agree with what I said doesn't mean you have to take over my thread with your opinions. This is dc's seed labeling and storage tips thread, not SpeedySeeds'.

So if you have your own preferred method kindly start your own thread please. Thank you.

sorry if i dented your ego bro

It's not an ego thing man, it's your abrasive approach when I even stated that there is another reputable method only that I preferred mine. You don't have to use my method, nor I yours. But at least be respectful to others.

I can't see any abrasiveness on here, apart from your previous comment.
