Ease of Culture, Phal. violacea or coerulea?

[ladyslipper]

Hi guys, I am on the hunt for either a Phal violacea or coerulea. Is one easier to grow than the other or are they much the same? I have been growing in east/north east windows without benefit of supplemental light or humidity other than standing pots on gravel in water and a humidifer in another room. I would appreciate it if any of you would tell me that I am setting myself up for orchid heartbreak or not.

Be honest; I am tough, I can take it! (really)
