Stanhopea wardii pbulb propagation question

[rbarata]

Hello, my friends

I got these pbulbs as a gift and I potted them one and a half months ago, more or less, and nothing happened so far.
The media is medium bark and leca (plus some traces of perlite).
The watering has been done with a syringe every two days, in the area around the pbulbs.
Temps and % has been around max. 28ºC (82 F) and 23ºC (73 F) min. % oscilates between low 30 and mid 40% (one of the reasons why I water it every two days). The pot sits in a south window, no direct sun, where I grow phals and catts.

I'm not sure if there's something not right...maybe temp is too high, I don't know. I can see tiny green roots but I think they're the ones that were already there. They show no signs of activity, don't die but also don't grow.

I would love some advise since this is a new genera to me.
