Fluctuating Low Temperatures on a daily Basis, Like in Nature - Good for Some Seeds ?

[St. Phatty]

I started out thinking, steady temperatures have to be better, temperature cycling can mechanically stress a seed, especially one that is part water.

But then I thought about Nature. Like, Outdoors.

Mid Teens overnight, maybe 35 during the day ... mid twenties, then perhaps up to 45 during the day ...
and so on, the normal day-to-night-to-day temperature variations you see outdoors.

I figure Nature knows what she's doing. Maybe some of the seeds LIKE the temperature variation.

I know it's normal for people storing seeds to put them in a fridge or freezer or at Svalbard in Norway.

I can't help but wonder if fluctuating temperatures, when it gets cold, is actually good for some seeds, in terms of making them long-lasting.

Not because it makes sense from a mechanical stress point of view - but because that's the way Nature does it.

Interesting thought...nature adapt or die really

.... Rethought the comment.....

don't some seeds need a freeze to be viable?

 

[VerdantGreen]

all the research on this points to a constant low (freezing) temperature and dry seeds for the maximum shelf life.
nature is trying to get seeds to grow, not make them last indefinitely.

it's true that some seeds need a freezing to stimulate germination, this is called "scarification" and needs to be done with the seeds moist (because dry seeds are dormant). cannabis does NOT need this treatment.
