Dracula lotax not doing anything. How can I adjust care?

[astrid]

Hello!

I bought a small dracula lotax in February. It had about 5 leaves then, but it has dropped two in that time and otherwise stayed almost exactly the same as when I purchased it. I repotted it as it was in green algae-ful moss and it needed it.

I keep it in a two-layer pot setup, and it sits in a smaller pot in the middle. The outer pot is just a plastic container. The inner pot is a clay pot. I have sphagnum moss that is constantly wet packed between the walls of the two pots to create a cooler temperature and more humid environment. Then the actual dracula lotax pot sits inside the clay pot which is not wet but just a bit damp at all times.

I avoid fertilizing because I believe people say these are sensitive plants to salt buildups. I mist the plant a few times a day when I remember, and wet the moss when it is approaching dryness. It stays evenly moist (but not soggy) for almost two weeks at a time.

The plant is sitting in a corner behind my other orchids that is getting shade most of the time, though it does get a little bit of indirect light.

It was originally in a mixture of packing peanuts and sphagnum moss, so I simply re-created that setup when I repotted it.

I am not using any special water on the plant, just regular tap water. My city generally has low salt concentration in our water supply - enough that other local growers use it on their native cypripediums without any issues.

As for temps, it simply lives indoors with me, and I try to leave the window open at night. We have 55-60°F at night lately and 70-80°F in the daytime, though it is cooler in my room.

Do you guys have advice?
The plant just sits around doing absolutely nothing while many of my other plants are in vigorous active growth.

I was thinking of putting the plant inside a glass vessel I have that is about 12 inches tall and 7 inches in diameter, but it seemed to get too warm in there even though humidity was good.

I will happily take any advice!
