Ok, thanks that's great info! Would love to see pictures of your summer set-up, Ken.
If it's not then the heat and humidity that's giving my phals trouble, it must be not enough air flow! Maybe I'll hang them all up in the shade and see if that does better for them. Last year they were all on a wire shelf unit in the corner between two patio doors (which I figured would leak some cool air from the house). That corner must have not had enough breeze for them.
