Hi...I grow and bloom a lot of Paphs. but not this one. I've had this for three years, last year it had sheath but blasted on me, this year it has a good size sheath it just sits there, been like this for 4 or 5 months I keep it dryer, but it's hard for me to get a big temp drop it's in the basement, quess I'll just keep watching it. Good luck with yours. Jim.
