How long do seeds stay good for?

[PhatNugz]

5+ year old (bag) seeds, stored in the chest freezer.

Very low germ ratio though.

Average 1 out of 7.

Nice. So did you top them quite early? I need to do mine soon. Probably should have done it by now but was worried it was too early to.

wouldn't be keeping seeds in a freezer , might be a reason for low germ rates 

just need to keep seeds dry & cool 

remember all kind of seed is store in soil outdoors waiting for the right conditions to germ

general rule of thumb 

top at the 5th node to make 2 tops & again at the 4th node of those 2 tops to make 4 tops 

both those times should have you topping at a parallel node point , which means the 2 branch sites

either side of the topping will compete to be the top making 2 tops  

 

this will turn your plant from a xmas tree shape to a wine glass shape

I was thinking the same last night when I read it, itchy. But apparently after Googling the subject last night some yanks seem to think -15C is the optimum temp.

I'm not sure how they come about to this theory, and I doubt it's a practice I'll be taking up anytime soon.

 

I'll keep mine in the the 3-5c range still, like was suggested to me by a oldtimer some years back.

I've heard it's ok to freeze them but you have to be be gentle or they can crack - shatter.

I suppose there'd be a right and wrong way to thaw them .

 

This place in Norway freezes seeds ,

i think it's around 140f in composting that will kill seeds

meaning if they were at 100f for a period of time they would still germinate afterwards

 

in a controlled environment & lots of testing , you can freeze seeds for sure 

there's billions of dollars spent to make sure of that 

 

not sure it be the same as our home environments 

i would like to know how they remove them from the freezer to be germinated ?

 

would they slowly raise temps to bring a seed out of a frozen state ?

 

pretty cool what they can do , look at malted seeds , they can germinate a 

seed & stop the germination process to trap enzymes for beer making 

& do it exactly the same every time , so a VB can is always a VB can

regardless where the seed was harvested

iv had seeds gifted to me in the past been a few years now and they are still fine store them in the fridge door, 100% germ rate every year
