Have you seen my Huntleya wallisii? The humidity is around 92% in the dart frog tank I have it in. Granted it does have good roots inside the basket, and it is a plant that does like quite a bit of moisture, so keeping the media dry doesn't really apply to my Huntleya, but notice that the roots growing in the air are growing like CRAZY!
The roots have grown about 1" in about 2 weeks!!! If the humidity was even 17% - 27% lower, those roots would not grow like that.
You want evidence, that's your evidence. I posted that for a reason. I wanted people to understand the power of controlling humidity for certain orchids.
Your Lc is not the same as a Huntleya, but the basic principle is similar. Jack up that humidity, and you will get the plants to produce roots, especially during growing season.
