germinating very old marijuana seeds

How old was the oldest Cannabis seed you ever successfully germinated?

Hello microgrowers. I wonder how long the cannabis seeds can be viable? I have some 10 year old seeds that I am trying to germinate. I don't have high hopes for them but it made me curious if anyone successfully germinated really old seeds. I realize it has a lot to do with storage conditions and the original quality of the seed but still, I would like to hear your stories about Frankensteining old beans.

Preemtively I will say that I also have some new seeds to plant. The old ones are "for science".

Update: My seeds does not seem to be viable. 🙁 Out of 11 seeds only one showed signs of life. It cracked open but has not produced a root.

I remember reading a post on one of the orher forums where a guy was trying to germ a bag of seeds he found in an old bag he brought back from the vietnam war. iirc out of a dozen or so he got a couple to pop.

I've germinated 14 year old freezer-stored Mazaar successfully.

Ive said it here before, but my grow this year is from 10 year old seeds.

I germinated seven seeds the week before 4/20, and six sprouted. The seeds were hanging in an open ziplock bag since summer 2012, and got heavily contact with light/uv light (in room temperature) 🙂

Except for one all came out very nice, bushy and very healthy!

I germ'ed some 25 year old seeds a few months back. They were not properly stored or anything, just sitting in a jewelry box. They sprouted, but they had lost a lot of vigor. Had they been cold and vacuum stored, I bet they would have done a little better. Eventually I gave up after 4 weeks waiting for the sprouts to root and take off, so I chucked them. You can always give them a shot and see how it goes. I'm also assuming what you've got is bag seed, which means the genetics could be all over the place. Just don't expect much and maybe you'll be surprised.

Cool that they germinated sad that it didn't work out. The seeds are White Widow, Sweet tooth #4 and Northern lights, from Nirvana I think. I bought them last time I did a grow and they have been in a drawer since. I roughed them up with some sandpaper and put them in wet paper towel.

I found a bag of seeds from the first outdoor grow I ever did that were about 15 years old. I was excited because it was a really good strain that my dad had been growing and crossing since the 60's and I wanted to grow some for sentimental reasons and possibly cross it with something new. There were a few immature little white seeds but they were mostly fat, dark, and striped. I probably threw 50 seeds between wet paper towels in a pyrex dish and not a single one sprouted. Sad. I still have a handfull of them in the fridge though, maybe I'll give it another shot one day.

More to the point, I have successfully germinated seeds that were around 10 years old and properly stored without issue.
