Hoping for the best for the recovery of your collection. Sounds like it was pretty touch and go for a bit.
When I had a larger collection than I do now I had one bedroom dedicated to growing the orchids under lights. I used to dread the electric bill but compared to the cost of heating a greenhouse it was a bargain. Also had a lot more "sunshine" in the Winter than if I were growing in a greenhouse during a Michigan Winter.
The good news is I'm a member of an electric co-op and our bills are quite low
compared to others I've heard about heating costs for greenhouses.
You're right Rob. I haven't seen any damage to the Phals. so far. Gotta get through
tonight at a predicted 9F. Are you kidding about $3000. a month????!!!! Oh, I forgot
you live in Michigan...way up yonder.
