White Egret Orchid

How are everyone's white egret orchids getting on? One of my three appears to have varigated leaves, which is a nice surprise.

 

All 3 have little shoots but no discernable leaves yet. It will be interesting to see if any of mine have variegated leaves.

 

One of my three collapsed and died. It seemed to be rotten at the base of the stem. The other two are growing v-e-r-y slowly. One has been an inch tall for weeks. I don't know whether to keep them indoors or put them outside, so I am putting them outside during the day and bringing them in at night. No sign of any flower stems at all. Maybe they won't flower for a few years until they get more mature.
Any luck people?
