I never worry about water in the crowns of paphs and phrags outdoors. Its different from an indoor situation, and air movement prevents a lot of potential rot, even when the rains are during the night... This summer has had some heavy rains- 2" last Wed, followed by high 90's the past 2 days...but I've left my budded paphs outdoors...they are fine. I have a sukhahulii about to open within the week, a barbigerum soon after...concolor is fine and 1 of my complex crosses even set a bud...Take care, Eric
