LIGHT, TEMPS and HUMIDITY for Aerangis/Angraecum ??

[NeoNJ]

I know this topic I posted recently, but I'm finding alot of conflicting information and need clarification, so I'm turning to the experts here ....

I have acquired a nice sized collection of Aerangis and Angraecum --- Most of them are all mounted, with the exception of Ang. didieri and Ang. magdalenae. They are all growing mounted on the inside wall of a large windowsill with SOUTHEAST exposure.

Most on the board seem to grow these in "terrariums".
So I need to ask what is the HUMIDITY Level I should be giving these orchids, and how much LIGHT. Some seem to be growing these in HIGHER LIGHT and some grow in Very LOW LIGHT.

Thanks for any help you can offer ......
