Title: Vacuum sealing for preservation
Post by: Greenie DeS on 2021-10-25, 12:08:44 PM
Seems like seed preservation is another use for my chamber sealer? Are there any best practices associated, for instance, are jars necessarily better than bags? I figure I never access the bottom 6" of my deep freezers anyhow, I might as well make use of how undisturbed they are.

Never looked into this before, but I found a link that shows vacuum sealed bags as well as jars, for long term seed storage.

I haven't frozen any seeds myself, but have read some comments about freezer storage.  People put multiple small packages of seeds into a mason jar to freeze for short term storage.   The best practice was to let the whole jar come gradually to room temperature before opening it to get your seeds.  This seemed to be a good enough method (without vacuum) for stored seeds that are accessed in the short term vs those kept long term.

This is something I've wanted to do for awhile, but have not yet.

One of the most harmful substances to long term seed storage is oxygen, so anything to reduce oxygen should help. I would think bags would be easier to use, but who knows. I've wondered if adding an inert material like fine sand would help fill in the gaps between large seeds. One of these days I'll get vacuum storage working. But even without vacuum storage, sand and filling jars up to the top probably could help.
