Then you go from that to this, and then they grow normal patience is all you need, I also feed my seedlings a nutrient mix of 1.2 EC and keep my PH at around 6 to 6.2 as soon as i transplant my seed.

They were stored in a Fridge and the seed were in air/light/moisture proof packs.

Seed store in the fridge should have up to a max of 20 years viability.

Seed stored in a freezer should have a max of 50 years viability.

You're not going to get 100% germination rate, but even 30% is all you need to find and select to make viable fresh seed if you store a good amount of seed to begin with.

Most old seed that germinate are fine, some will start normal and then stall and look like this and stay like this for a week or a few weeks then just start to grow normal overnight.

not saying that you are wrong, just wondering where you are getting your numbers from when you say how long seeds should be viable for when stored in a freezer?

The University of Hawaii some decades ago had all this information on seed preservation available for free, I found it in 98 or 99 and first posted the links and relevant information up at Cannabis world. A few years later, you could no longer accesses the information and the links no longer worked.

I don't freeze seeds my self, I use the refrigerator method and the oldest seed I have germinated so far are those pictured above over the 20 years they gave.

Seeds stored don't like temperature swings /Moisture/ or light, and freezing seed has a longer storage life, but once you thaw them you can't re freeze them. You also need to dry them and prepare them before freezing, or they will expand once frozen.

So if stored in a freezer, and you have your freezer go you're screwed but if your fridge goes you have options like an esky and ice until you get a fridge replacement.

You also have to consider the possibility of blackout.

Chopped the males just now, saved 5 for reveging in the clone tent
The 5 labelled and kept are 2x Thai leaning, 1x Colombian leaning, the one with the white patch on the leaf (it turned out male) and another male that was the only one of the whole lot to have a red tinge on the top half of the main stem. I think that one might interest @Stoneguru
Saved a little mixed pollen for the freezer. If I want specific pollen now is not the time to collect it!

There were clouds of pollen as I chopped them getting sucked out through the female tent, as if the females aren't seeded enough!

I found some pdf's from UoH but not sure if any of them are what we seek
These growers follow the “Rule
of 100.” The rule of 100 states that the sum of the tem￾perature (°F) and the relative humidity (%) should equal
100. For example, refrigeration at 50°F and 50% relative
humidity fits these criteria. Seed dried to 2–5% seed mois￾ture and stored in the refrigerator in an airtight container can maintain viability for decades

I worked in a germoplasm bank in my country, where the government stored all the seeds of the biodiversity from all the country and a little of other countries too. The installations was a big refrigerator with a dry cold (-20 °C). They storage the seeds in plastic bags that doesn't allow the lights enter on them. They can stay the seeds there for many years, but also does it germination test in laboratorys. I saw many ways of how germinate different seeds, since stratification to in vitro. Just keep the seeds dry, cold and far away from the light and everything is going well.

I wonder what kind of cannabis they put in the Svalbard Global Seed Vault.
i think that they plan on the seeds lasting more than 50 years

Just from my own experience, the refrigerator model and predictions they gave all those years ago were prity much spot on.

I found say at 17/18-year-old seed was still giving high germination rates then after that it dropped sharply, and I had to then start trying things like Coconut water GA and things like that to try and get and increase in germination.

So far the 3% Hydrogen Peroxide and RO water works the best.

The seed packs I got were light/moisture and lightproof, you need a hot ion to seal them.
