They grow outside in my greenhouse, which has a polycarb roof and shade net sides and only come indoors when in flower. Both the Sarcochilus harmanii and Sarcochilus fitzgeraldii flower easily. Will post a photo of the Sarcochilus fitzgeraldii tomorrow.
 
So far I didn't know much about Sarcochilus ... but I must say both of your plants look great, great culture as well as great and lovely flowers. 👌
 
Well grown and flowered!

Mine just grows with no flowers lol.

What do you think triggers blooming? Low night temperatures?
It most probably is the lower temperature during cooler winter months. The inflorescences start developing during July and August, which is our winter. Our night time temperatures during that period range between 1 - 7 degrees C and daytime temperatures 14 - 18 degrees C. We live on an estuary and it is fairly humid and damp through the year, which could possibly be an advantage as well.
