Can you use weight to tell if they’re dry? Asking for future projects as a total novice to drying seeds.

I just leave them in a big dish so they’re not piled too deep and let them sit for two weeks and call them done.
I might even stir it once or twice.

Hey yall
Just to piggy back a little,
How do people organize seed within the fridge? Its tough without a standard sized pack, some breeders are on big or thick cardboard backers, some in little envelopes…
Ive seen a few binders on here
Im currently using 3.5" floppy disc storage boxes.
But its not super organized

Idealize the moisture content and store in a cool dry place with the least amount of temperature and humidity change as possible. I’ve read as low as 6% moisture up to 12% being a representative of an ideal range of seed moisture content. I’d imagine there are subtle nuances within these values as they relate to seeds of varying shape and construction. Some having thinner shells, others thicker, some rounder and others more oblong. I’m not sure how these things matter but I’d imagine they do.
It’s important to limit variability in the storage conditions once they’re in storage. Many blessings and much love

Seeds you will run in the next two years keep in the fridge and the rest in the freezer 
…I use plastic rubber seal airtight containers which is inside a mylar bag with dessicant pouch and the seeds are in a plastic vial/tube with a bit of sterile cotton

I used to have all my packs in a coffee container, filled a third with rice, then my seed packs, with plastic wrapped over the top, held with a rubber band, and put in the freezer. Now that’s where I keep the primo shit, the rest gets zip lock baggies in the freezer.
Mine are in an air-tight aluminum tube, along with silica dessicant, in the produce box in our 'fridge. I haven’t been storing them for long enough to know how effective that method is long term, but I’ve had a 100% germination rate so far, with seeds stored that way.

Freezer is the best. Refrigerator is not as good as most people think. I’ve been doing tests for 35 years and believe me when I say as soon as they dry put them in the freezer and don’t ever let them thaw out unless you’re ready to start germinating. They will almost certainly outlive you if stored this way

Hi @Bert I dry them in the dark in a box of matches.
And then I store them in test tubes like that
which i put in a Tupperware box in my fridge.
Hope this was helpful
See you

I love fridging seeds. It winterizes them and they germ much faster. 4-5 years old pop 24-48 hr in warer.
Also they dont get dry af. Old seeds in cabinet in rice seem so brittle to me.
Lucky here humidity is low so not much condensation is made in the little tubes bottom drawer. I put silica pack Outside the seedpack.

I always wondered if it destroyed the seeds but u got the rh right it seems gj. Do you vac seal it?

Nope on the vac seal. Just in a jar at room temp and whatever atmospheric pressure happens to be, then in the freezer. Only thing I really control for is humidity. It definitely works for bud long term. Seeds, I think the oldest I’ve ever popped is ~7 years, so I can’t say for sure this will keep seeds well truly long term (20+ years) but I would imagine it would.

From my experience, keeping them at room temperature will only give you less than 10 years. More like 5 give or take a few.

Bought in 2003 from Nirvana, Aurora Indica (far right) stored in the fridge for 21 years. Her and her sister both broke soil in 3 days. I have 3 Blue Satellites I’m going to run soon.

Wow that’s a beautiful plant. Nirvana used to have some of the best! Great to see the older varieties coming back into production!

I have a nirvana California orange bud that’s been kicking since 1997. It’s been reproduced a few times.

Any tips or tricks starting 20 year old seeds that have been kept in vials in the dark?

Temps/humidity?
I’ve done 25 years with no issues but it was cool and dry the whole time.

You can put them in the freezer for a couple of weeks. All my seeds go in the freezer for long term storage and I think that helps a lot to “ break dormancy” in the seed. However, I have no idea if it will work for old seed stored at room temperature.
