First Phragmipedium, no ID

[Leafmite]

During one of my latest orders, I noticed the option for a free orchid, orchids the vendor wishes to unload because they do not meet their high standards and/or the tag is missing. I decided to give it a try. The orchids I ordered were all very nice but the free orchid turned out to be something that I did not recognize. Fortunately, a hand written tag labeled it as a Phrag.
The problem is...I have never grown a Phrag before. Any ideas on what general type of Phrag this is and how I should grow it?
What I have done so far with it: I put it in the miniature greenhouse with the Phal. bellina (there is a heating pad under the greenhouse to keep everything toasty). I plan to water it often (with distilled water) to keep the LECA damp.
