Phals in vivarium question

[Easternone]

Here are pics of the vivarium
(it won't let me post the link but it's imgur . com / gB8vH,C4D4v )



as you can see, the water drips from the entire underside of the tall branch, keeping the moss (where other orchids shall be mounted) moist but also wetting the flowering Phal
I decided to set the rain on a timer to turn of late evening and the fan to come on full to dry the orchids overnight which should keep them healthy right?
