I moved my Phals to this north-east facing window and got a regular 4 tube fluorescent light about a year ago or so. They don't get enough humidity and I frequently forget to water them and they all need to be repotted, but the combination of the artificial light, the window, and the fluctuations in temperature at night have triggered bloom stems on all of them. I have one with yellow flowers that has buds that haven't opened yet. I find that I'm more apt to kill the yellow phals than the pink ones. The lights have been raised about six inches because the bloom stems were growing into them. I turned the plants to take pictures because all the flowers face the window.
