[PRIMROSES] starting primulas from seed

I would like to hear from experienced gardeners who have succeeded in raising
primulas from seed.  I have had very mixed success.  Primula japonica was no
trouble.  I grow most of the seed (which I get from the American Primula Society
Seed Exchange) under lights in my basement.  The temperature is about 65 degrees
and since the only place I have room is the furnace room, there is very little I
can do to get it cooler.  Is 65 too high for good germination?  The other
problem I have is green mold on the pots.  Last year I put a thin layer of fine
sand on the tops of the pots, but it didn't help.  I use 4-inch pots and wet the
medium (a mix of spagnum moss, peat moss, vermilulite, and perlite) before
sprinkling on the seeds.  Then I wrap each pot in a baggie and seal it with a
twistie.  Is this method blocking out too much air?  Should primula seeds be
scarified?
Any suggestions would be apprciated.
