ok, thanks for that.
My environment is basically a big window, in summer I get RH 50-70, however now with the heating is around the 40s... in terms of temperature during the day it remains around the 15C and late evening 20s C...the plants are below a little opening on the window, and my sphagnum moss gets dry quite easily, so Im guessing its providing quite some airflow. Its a west window a bit tilted towards north, but heavily blocked by other buildings, so my light is rather low, I just added 2 small growing lights to help a bit.
At the moment what I have in SM are phals and an oncidium, what require less humidity. However 2 other oncidiums I don't have in SH are creating some light accordion shaped leaves (the roots are not rotten), even when I spray the spagnum moss they have on top when its dry and water them when the soil is getting dry 2fingers deep. That's why I am quite concerned about an orchid that requires such a high humidity.
With those conditions what do you think?
