Masdevallia floribunda care

[stompy]

This is my first Masdevallia so would really like some pointers on care. I picked this guy up cheap from ebay thinking I'll try to grow a easy one first up.

I'm in NYC and primarily a windowsill/artificial light grower. Summer temps hit 30C/86F. I can maintain humidity 60% and above. All my plants are in semihydro and are doing incredibly well under my conditions

But this was a Masdy so I bought a kool-log and mounted the floribunda on it yesterday (I got it yesterday). My reasoning was maybe my conditions would be too warm for the plant. The plant looks very healthy with new growth and roots. It was in moss and is on the kool-log with fresh moss. This morning I toched the kool-log and was shocked to find how cold it was. The moss is also very wet. I have a fan going 24/7 so my grow space has good airflow.

My question is, do I really need the kool-log for this species? I think this is a warmth tolerant species so under my culture conditions should I just switch to semihydro? or stick with the kool-log. I don't really want to kill this because I kept it too cold. I'm tempted to buy a temperature probe and stick it in the moss just to see with the internal temperature is.

Any/all advice on this species (or any other warmth tolerant ones)will be very much appreciated.
