I set astrantia in autumn, outside. I generally bring the overwintering seed pots into the cold GH around February. this might be more for my benefit than theirs. I also bring things in when they germinate, no heat, just shelter from the worst of the wet and pecking birds.
verbena about February in the cold GH
I use gritty compost and some more grit on top of the seeds, it stops them getting washed out or growing mould/algae/other undesirables
