I'm in the middle of re-organizing and cataloging my seeds which have been tending to get more and more dis-organized as time flies by. .
I kinda like the binder storage system, but someone  here at THP had their collection in pill vials and that is the route I've decided to take.
A one ounce vial is about 1" dia x 2" tall and will hold practically an "acres-worth" of pepper/tomato sized seeds.
Even for cukes and winter squash a vial will hold a few years worth for a  garden of my size.
If I were to get into corn and beans, I'd have to move more toward pint jars.
Organizing is my bane, so I'm routing sheets of Plex  or possible High Density Urethane (which ever I have good scrap of at the moment) about 14" x 18" to hold 80 of the numbered vials in an 8x10 array. I've got enough vials to fill 5 sheet arrays. (That should out last the rest of me.)
Â
A seed lot is then assigned to a vial until it is used or proves non-viable and then a new lot is assigned to that vial.
The cap and vial will have a permanent number and the vial labeled with the particular seed lot's ID number and details and relabeled when the lot changes.
The database to store this info is coming along, but I'm pretty rusty in MS Access, so it has been slow at best.
Â
The array sheets I'll store in some kind of plastic tote in a dry, cool, dark place.
