I put my MG seeds into warm water and let them soak all day and night
and plant the next afternoon. Right now I've got some Japanese MG's
soaking for planting.

I find with hard coated seed that if you put them into hot water
that you
can only just put your hand into, and leave them there till the
water goes
cold then they will have taken up sufficient water to start growth.
What happens is that the hot water expands the air inside the seed
coat (if
you look closely you will see small bubbles) then as the water cools
then
the remaining air contracts and draws in water.
With very heavy seed coat or shell then I use almost boiling water.
If you have seed that is floating after one dose of this then a
second go
with slightly hotter water normally works.
