Milt(onia) vs. Milt(oniopsis)??

[theredhead]

I'm confused on the whole Miltonia vs. Miltoniopsis differentiation. I was looking for some orchids for the north facing (Colorado) windows at my office, and the nice folks at Fantasy Orchids suggested milts. I came home with 2 in bud, which I'm already enjoying. I have:

1 pink milt (vexillaria x Lady Veitch) w/2 spikes, just starting to bloom.

1 red milt Arnold Linsman 'Hot & Spicy' w/2 spikes, will bloom in the next couple weeks.

I believe they are miltoniopsis?

I would appreciate some guidance on the difference between the two, as when going some quick research they are often just referred to as 'milts'. I've ended up with some conflicting information from people.

Several specific questions:
- do the plants I have want to be watered more often, or allowed to dry a bit?
- how long does it take the blooms to open? They seem slow compared to my white phal.
- mist daily?
- would they benefit from a supplemental light?
- where can I buy (online) more of these lovely plants? I'd especially like some yellow.

Thanks.
