Pete, I may have missed something here. But where do you hang your Phals.? In a shade house, or under a tree? My temp. here is at the moment is 84 F during the day, and 66 F at night. It will be like this now for the next couple of months. At the moment my phals. are kept in the bathroom all the time on water-pebble saucers. Their potting mix consists of sml. bark, coconut husk. I'm worried that as this is their first summer, it may be too hot inside the house. I have four and I don't want to lose any. Any suggestions?
