Sophronitis riograndensis struggling
 

Hello everyone!
So it's about acclimatising mostly. I have bought this S. riograndensis about 6 month ago, since then it dried out slowly 4 new growth it came with, then dried out almost all the leaves one by one and actually some bulbs. Now I am almost sure it's its last month. The green bulbs are firm,
no real rot signs (and I assume it would die much quicker).

My temp are about 25C day, 20C night, humidity 70-85% (the joy of living on the island), and just the next pot with it a Sophronitis brevipendiculata from the same vendor is going just fine, have matured 3 growth and starting 2 new.

Any thoughts? Or may be it's already to be buried in the garden to stop its suffering?

Thank you!

Is it indoors or out?

Its indoors, but I never close the window in orchid room from March to December approximately (Southern Mediterranean climate is mild)

The moss seems too dry.
How do you water it? Frequency and what type of water (distilled, tap water, well water?)
I also think it would benefit from lower temps at night.
And what light intensity are you giving it,

I spray from the close until moss is wet, in summer I was doing it every day or even twice a day (supposing that it has insufficient root system so trying to balance it out), now I do it once in 2 days. I use air conditioner water that I use for all my orchids, adding fertiliser once in 2 weeks in summer.

As for the light, its under the led light 12 hours (at ca. 90 umol/m2/s) but also it receives indirect sunlight in summer during the day (ca. 140) and this season it has 2-3 hours of filtered direct sunlight (because of season change).

I'm not an expert on artificial lightning but making some conversions it seems the light you are giving it is too weak.
It depends on the type of leds, I think, but anything under 1000 fc is certainly not enough.
Let the lighting experts give their input.

How far is the plant from the light source?

The number I quoted are the actual measurements from the leaves level. I will check them later tomorrow again.
UPD so we have around 1300 fc for 5 hours and 12 hours of 250
