I believe the best way to store seeds is in the fridge. I wrap them in a paper towel and place into a jar full of rice (uncooked). The rice will absorb any water that might condense inside the jar, as well as the paper towels. Then I wrap the jar in foil to keep it dark and more air tight. I change out the rice once a year.

They will keep for 10+ years this way, the problem with the freezer is most have a defrost function which creates condensation. I think if they were in freezer with no defrost it would be better.

I would like to hear what your germination success rate is with these seeds, good luck and sorry about your loss.

I have several different high grade strains stored long term and have gotten 100% germ rate with 6 year old seeds stored in the way I have described.
MtnLionCO Reviewed by MtnLionCO on . 20+ year old frozen seeds I looked around for anything similar to my question in these threads but could not find anything remotely close. (I could have missed some threads, though.) I had a friend pass away recently who had kept seeds from the best weeds they had smoked starting in the mid '80s - early 2000's. They kept them frozen. They didn't note the strains or anything more than, "kicked ass" - "mellow" - "couch potato locked" - "fucking unbelievable high" etc. so I have no way of knowing what percentage of Rating: 5
