Re: Alpine House Propagation

The greatest number of alpines germinate best when exposed to several 
months with night temperatures in the 30s [F] Refrigerator temperature, 
that is.  If your alpine house stays above 40 F most nights, I'd expect 
lower germination for species requiring stratification. [Note that one of 
your favorite groups, Androsace, generally germinate at refrigerator 
temperatures.]

I generally cover my seed flats with recycled window screens: this lets 
rain through, but keeps it from washing the seed around.  The only 
problem with covering with plastic is that, for me, damping becomes a 
problem.  Exposed to air circulation, fungal problems vanish.
