I've an avid seed collector and I store all my seeds in various sized plastic baggies. I've heard that this isn't good for the seeds and that paper coin envelopes are much better. What does the group use or suggest?

Prepare yourself to receive a ton of different answers!

I put most seeds into the little plastic 'baggies' but for tiny seeds I go all Origami and make a little folded paper envelopes to hold the tiny seeds, then encase them in the plastic bags.

I'm prepared. I must admit that I've not had any problems with seed germination from those I've stored in baggies.

The important part is to keep your seeds dry and cool. And label them. If kept properly, most seeds will last a really long time.

I store mine in plastic bags that 'zip' shut in the crisper of my refrigerator. For tiny seeds, I save tiny plastic bags. I get a steady supply of them by walking around my neighborhood a couple days after the business card sized 'coupon bags' show up on people's driveways. If they are still lying on the sidewalk, they are mine.

I store smaller bags of seeds that have something in common in larger bags - its my filing system. Sometimes they are sorted by when I need to plant them. Sometimes by where I got them.

I keep my seeds in paper envelopes (origami style) and organize them chronologically in 3 or 4 inch plastic pots, which go into basement storage after a year or so. The square pots can be stacked densely. I rarely go back more than a year when I'm in the archives, anyway. Our indoor temps are in the 60s or 70s most of the time and our average humidity is 80%.

Thanks Daisy and Baja, I've got mine stored in the large lidded containers you can buy in the office supply section of WM. They're haphazardly put in there but I have two of the large 'super stacker' containers full. I don't have a basement but our indoor temps are usually in the lower to mid 70s with about 50% humidity.
