I meant to add a comment to Chipmunk. On the prairies here we consider 60% RH to be med to high for orchids grown indoors. In our homes our humidity is more like 30 or 40%. I keep mine in a greenhouse raised up on trays with water in so I do manage to keep RH at around 50 or 60%
When I was growing these, we did them in small pots, but never let them dry out. Ever. It was really important to water them before fertilizing to flush excess salts. Water quality important, too.
The hybrids were all pretty easy in mixed-collection conditions (in with Paphs and Phals) so long as we kept the roots strong (see above). Milt. vexillaria and Milt. phalaenopsis were a little fussier - they really don't like getting up over 85 degrees f for any length of time.
Mltnps phalaenopsis can handle warm temperatures in excess of 85 F if the air circulation is excellent and the evening temperatures drop significantly.

It was the lack of nighttime differential that was problematic for us in the summertime in the Midwest in a greenhouse! Good to hear it - it's a dandy plant! They always came back nicely in the fall - just looked like death warmed over by the end of August if we didn't cool them down...
Mine is opening some flowers just now (not taken pics yet).
Mine has masses of roots and seems a strong healthy plant but still the new growths are about half the size of the old ones.
I do know that despite the good roots I'm underwatering because the new growths are wrinkled, not sure if this is the same reason they are smaller or not, but it could be.
I think that maybe they prefer to be watered through rather than stood to absorb water in the cache pot like we do with Phals. I lost one very early in my orchid owning career because of rotting roots. The growths on that were getting smaller and smaller....
I've done well with them in the past, but lately it seems I've lost my ability to keep them thriving. Ditched all but a couple when I repotted a week ago. Here's a shot from some I got from Ivan Komoda a few years ago:
