Seed Shipping add Freezing.

At Svalbard Global Seed Vault the storage temps are 0 F and if the facility has a mechanical issue the permafrost will still keep the stock frozen and secure . I do also know many breeders and preservation growers who store all seeds in the freezer . But with that said the general rule in the industry is freeze once only . All bets are off in they are refrozen .. I do not really believe this rule as Nature can and does subject seeds to random thaws many times during the changing seasons . I used to skip school and travel down into Indiana to collect ditch weed , good old industrial feral hemp and it still grows there regardless of our govts many attempts at eradication . While exploring we always left good seeds in the dirt in hopes of a random hybridization lol . As for beans being frozen in the mail , no worries as I usually just place them into my own freezer for long term storage when they arrive like so , or I thaw them out for a day before attempting to germinate .. Peace .PotSnob

Seed vaults ensure the moisture content is below 10 percent before they freeze to prevent cell damage. I am concerned the seeds I payed over 100 American dollars for could be damaged in transport because the breeder may not properly dry the seed?!

Four year bump...

Rarely ever is fresh seed stock distributed by the vendors, it's going to dry usually by the time it gets through the channels and finally to you. But this whole thread seems redundant if one understands natural order and just how amazing spirit seeds are. Some of the things I grew in the past few years came from seeds made with seeds over 500 years of age discovered by archeological digs that returned our seeds to us through the repatriation act. I guarantee you nobody was worried about the water content before burying the ancient tobacco and squash seeds which were frozen hundreds of times.

The real thing to be concerned about when purchasing seeds I'd say is strength, much of the modern bottlenecked weed is weak and the seeds might just go bad in a freezer within a year. But there's people popping seeds yet from the 80s that were subjected to more than anyones seeds that got frozen in the route of delivery. These are powerful spirit seeds, and most of them seed bank beans are just that. Commodity, it's why they wind up in the seed bank. We at Manidoo only release limited drops and the seed banks are yet only a option at this point.

Had that happen with Dr Greenthumb seeds. They were a sale item and shipped during winter. Tried them a few weeks later and got seeds that popped but never grew. The roots barely made it 1/16th of an inch. All my other bought and my own made seeds did fine under the same germination regimen. Same that had happened when I made my own seeds and froze them during summer in high humidity after a long "drying period'. You have to use dessicant before freezing seeds from my experience and they'll do fine for years in the freezer if they are sealed

Seeds that germ yet fail are lacking the hormones necessary for growth beyond that initial push after the seed cracks. Some of the best of the hyperbole and the rest of the modern weed is plagued by this breeding indentation

I've had it happen with old seeds of mine that germinated well for years. It's not strictly a problem of inbreeding. I'm sure it has many causes.

And I'd bet they knew quite well about water content and freezing seeds 500-1000-2000 years ago or they wouldn't have survived as a civilization.
