I have 'hatched" seeds many times in a fridge over summer. Normal
fridge temperature. These are planted flats of seeds that didn't
germinate over winter. Inevitably the seeds are germinating after
three months at this temperature, as long as they didn't dry out. They
start to germinate in fridge.
Great germination this past winter in cold room in garage. I had a
small space heater on low to kkep them from freezing. the ones that
dried out didn't germinate well and are now in barn fidge.
Worst germination ever was when I had seeds in cold greenhouse. The
high temperatures resulted in very low levels of germination.

Too hot or too cold at the wrong time are bad, but I don't have
Too cold is maybe below 25oF? just as seeds are about to sprout; too
- - don't know, but I worry above 70oF - if they do sprout, they are
likely to damp off or fizzle.
After having burrito bags occasionally freeze in the fridge, I've set
higher to make sure it always stays above freezing. Seems to be better
germ that way. After planting, try to keep seeds below 60oF,
in the 40s at night, no higher than 70 during the day.
Maybe others will comment - I haven't checked the archives, but seems
like Vickie Craig posted something about germination temperatures for
There's some combination of warmth and drying conditions that stops?
slows down? germination in spring - used to think it was just warmth,
but this spring, all the rain, or maybe the genetic mix (Oz & CA genes)
kept things sprouting later/warmer than usual. Or maybe the maximum
lower. Don't know.
Some seeds germinate at refrig temps - 40oF? Mary Lou has seeds in the
fridge germinating after 2 yrs there (I think)!
<What temperatures have you found to be good or bad? David>
Not much good information - hope that helps.
