Best Way To Store Seeds and How Long

any sterile, airtight container will work.

i usually use dime bags or tiny glass vials

with a proper airtight seal, in a cool place, seeds can remain viable anywhere from a few years to theoretically indefinitely

I keep mine in the fridge as per monkeybones.

Airtight container and out of the light is realy all you need. Sock draw works great.

cool, dark, and away from any moisture as stated above

I keep seeds in my fridge inside a sealed, wide-mouthed ball/mason jar that has 4-5 of those silica gel desiccant packets in it. They have been there for around 8 months now. Popped 5 of them back in April and they all germed so it seems to be a viable storing method. As others have stated: use a cool, dry, dark place.

Some good links on this page. The whole tread is a cool read. Not sure which page but they really talk about storage. lol, 1007 pages

If that tupperware is airtight, then you have it knocked. Should be good 10 years or more stored in fridge. Freezer lasts longer but you can not have frost free freezer. In other words, the seeds can not be allowed to thaw out and then refreeze them.

I use glass vials I got off ebay, but whatever will allow no moisture or air in, will work.

those silica things for the moisture - i guess it depends on how many seeds you have and if they are in paper like mine, but you can have too much of that stuff and it will suck all the moisture out of the seeds, i have my seeds in an airtight container in the fridge, with about a 1/4 teaspoon of the silica grains - i have a batch of seeds im using from 2008, last week 19 of 20 germinated overnight ..... less 2 more now because of the dog! i have have just started today 6 kc33 seeds that are almost 10yrs old, ill let you know how they look in the morning
