I have a few pots of paphio and not all of them has bloom. It is quite tricky to trigger the flowering but when you managed to make it bloom, it is an achievement!
A friend of mine managed to get his paphio rothchildianum to bloom using this technique. In order to 'stress' the paphio, he made a box covered with paranet and use it to cover his paphio for 6 weeks. the cover is only opened for watering the paphio. After 6 weeks, remove the paphio from the box and expose it to 10-20% light and hopefully it will bloom.
I've tried this technique, and after 5 weeks out of the box this is the result!
