Thus the high frequency of application.
    Thank you - I'll look for those. (But not the Thai liquid!)

    Hi, do not know your conditions, but it may help after doing the things suggested above, to increase the air movement near the plants for some time, if you had not already done so.

    Thank you, Alice - I'll move the fans a little bit closer to them. Thanks for the tip!

    As Alice said = Increase air movement around your slipper orchids. And remember, it takes slipper orchids a long time to heal. We had a fan go out two summers ago when the temperature was 100+ outside. The greenhouse got up over 140 degrees before I got a replacement fan. We lost lots of plants and my paphs suffered terribly. They are just now starting to look decent again. It takes a long time when they get damaged. Patience.

    cheers,
    BD

    There's that word again! "patience" - seriously, thanks, Bruce - it helps to know how to put this in perspective.
