What humidity and temp. range is recommended immediately after repotting to s/h?

[AndreaK]

I know warm, shady, and humid is recommended while establishing new roots in s/h. What ranges are we talking? My room temp. right now is 77 with humidity around 76% to 80% I just finished repotting so I do not have a full range (high/low - day/night) for the room. I will try to update tomorrow. A seedling heat mat will arrive on Monday, hopefully. (Plants switched so far: Oncidium Sherry Baby, Maxillaria Tenufolia, Phrag. Laura Lei Quintal, Phal. Kaoda Twinkle, Pot. Mem. Jim Nickou 'James' HCC/AOS x Blc. Love Sound 'Dogashima' AM/AOS, & Masdevallia 'Peach Allure').

Next question: My Masdevallia 'Peach Allure' was also put into s/h. It was previously grown in a bark mix sitting in a tray of water. My question is : Do I put it in the warmer/more humid room to establish or just put it back where it was happily growing since it was already growing in a s/h way, just in bark instead of PrimeAgra?
