Sweet, thanks those look like they’d work well. I’m currently storing them refrigerated, vac sealed with some silica gel packs.
I have read a few places seeds can be frozen for long term storage with little impact on the germination rate. The longer it is frozen the harder the seed coat gets though, and it might have to be scuffed / scratched for proper germination.
I am probably going to freeze a couple packs of seeds this winter in the chest freezer or something. If I take them out after 4-5 months and I get them to germinate I will most likely freeze all or most of my seeds because they will only last so long the way I am doing it. Just want to be positive before I throw my whole collection in there, I am very cautious.
It makes sense to me though. There is that Svalbard global seed vault, apparently the seeds there are all kept at -18c. Don’t know why cannabis would be some kind of special plant that can’t be frozen like most of the rest.
Here’s a little copy and paste from the Wikipedia page:
“The seeds are stored in sealed three-ply foil packages, then placed into plastic tote containers on metal shelving racks. The storage rooms are kept at −18 °C (−0.4 °F). The low temperature and limited access to oxygen will ensure low metabolic activity and delay seed aging.”
