Stanhopea wardii pbulb propagation question

[rbarata]

Here's an update on my stanhopea...and a question.

I'm going on holidays for a week and I'm affraid about some of my orchids, especially this one 'cause it's too young (you can see the real size of the young shoot by comparing it to a pen).

We are having outside temps around 35 ºC (95 F) and min HR around 20%.
Inside my house the temp have been stable on the 26ºC (79 F) but the HR remains around low 20% if I do nothing.
Starting today, meteo guys are predicting temps above 40ºC (104 F) so I estime an HR of less than 15% inside and a temp around 29ºC (84 F).

My question is: under these conditions what can I do? All my orchids use medium bark and leca. I'm worried with my new shoots since the other orchids I have are used to these conditions (at least this happens every years without any losses so far).
