Multiyear seed storage options

It is better in the original packaging and add some other packaging. Although I don't understand why the seeds need to be kept frozen. After storing seeds over 3 years old in their original packaging, in order to germinate them you will have to cut or saw down the seed coat to allow moisture to penetrate inside the seed, let me tell you this, you can germinate a very old seed. , but you'll have to do a little work.

Do not freeze seeds. I am not a fan of putting them in the fridge either. Best way is somewhere with cool, stable temps and in the dark and placed in a sealed jar with 20-30 rice grains, in my experience. Seeds have been good for 5+ years when stored this way.

freezing can be a very good way to maximize longevity, BUT if the moisture content of the seeds is 'wrong' you'll kill the seeds as that water expands as it freezes and damages it. If you can't measure or ensure moisture levels, this is dangerous. Fridgerators have wildly swinging RH% levels. this is also not optimal. If it is in a vacuum sealed bag it might be okay? but even that after years humidity might creep in, i wouldn't know for sure. anecdote - i made fem seeds 3 years ago. they still germ 100% and all i do is throw them in zip lock bag in a box in a drawer. I have higher humidity in summer months, but the AC helps some but not all of the time, so their exposure is not controlled. They probably experience too low of RH in winter months, so it is far from optimal. So, maybe vacuum sealed and in container that is airtight with a lower RH% boveda 2-way humidity pack, if you wanted to be super anal about it. This would avoid high RH swings of the fridgerator. Maybe a wine cooler with a thermoelectric cooling element? That might not need the 2-way RH packs. Believe those result in much lower RH levels than a compressor based fridge. Also, if they don't have a date on them when you receive them, they could be 1-2 years old or more when you get them, too. don't assume they are fresh.

I don't think cannabis does well in freezeing temps for seeds, its not a plant that need a cold scarification in order to germinate and long term cold storage could dry em out to much. I store mine in little tubes inside the fridge 4c, and before that I stored them in a drawer that was dark inside sealed jars. Had things germinate out of that method that where 3 years old. Can't reply to your own question anymore because morons wined that people where using that to cheat in a contest about getting questions answered and they would answer their own question for more points... but its very easy to see and fix. You can however use your DM inbox. its the little paper airplane looking icon in the bottom right. Its grey when theirs no new messages/empty and green when you have new ones.

Rate of good dropped like 80% after fridge ( despite beeing at the back of shelf) after first year. Dark place, with stable humidity, with constant temps, something like basement cupboard or some storage place in the house with stablelish 17-21 all year long and i had 6-8 from 10 even after 5 years. I use soup thermos as extra to stabilize temps and humifity. My personal experience is this ....

If you want to freeze the seeds, you need to make sure they are completely dry first and properly sealed. I would rather go for a fridge personally, the temps are low enough to store them safely for a few years. Using them after being cold, it's important to let the seeds get to room temperature before opening the pack. Cold seeds will get condensation on and if you're not planning on using them all, what you put back in the fridge or freezer has a high chance of being damp and that will cause trouble.

Also seeds will last a couple years just in the sealed bag they came in if there kept indoors and not put under extreme Temps

Hello there good morning I think freezing would be an option Personally I would leave the seeds in the sealed bags they came if you don't have a sealed bag morning want to remove them I would put seeds in small paper envelopes. Then I would get some new mason jars and store the envelopes in mason jars. I would Personally leave then in a sparebed room closet where the temp does not change much. If you wanted to go to the extra ypu could install a dehumidifier and an air-conditioner in the closet keeping the temp at around 55 to 60 degrees and humidity at 40%
