Baby it's cold outside...

OK, not really.  But it is cold for Cattleyas.  Temps have been getting to low 30s at night which means my half-baked "greenhouse" heating set-up results in temps in the low 40s.  Too cold, but at least the plants won't freeze to death.  One day I'll have a proper greenhouse and maintain temps in low to mid 50s at night.  I'm sure the collection will be much happier.
