I'm doing laundry from my trip, and realized that the dryer vent blows nice warm, humid air right out to the orchid vacation camp.
Hmm! A new cold night strategy! Little tent of frost cloth, and a load or two of laundry drying when I go to bed . . . wish I had some warm air for my tomato plants c/w flowers!
I have new growth on the Brassavolas, too - Little Stars has two spikes and my big noid that was falling of the cork backing has three! I tell you, they like it when I go away.
