Gastrochilus japonicus~How to get blooms?
 

Seven years ago I purchased some mounted orchids at our local society show/sale. The Gastrochilus japonicus was in bloom (October). I hung it in my shower, and it grew pretty well. This past summer, I placed it in a terrarium tank with proper lighting and humidity-it has really taken off. Many new leaves and roots. How may I help it create blooms?
Thanks

Bump. I've never grown it.

It's a relatively cool growing plant. Maybe it needs a cooling period in fall to set flowers?
