Help with a few oddballs

[MAli]

Hello,

I have some plants that I would like to ask a few specific questions about and google is not doing it for me. I am growing these inside paludariums so if anyone has kept some of these plants any input would be greatly appreciated. Getting information directly from someone who grew a plant is truly the best. I am mainly concerned with how close to the lights to keep them and just how moist they like their mount to be. Other things like flowering and any special needs would also be appreciated. OK enough talk here they are :
- Oeonia oncidiflora
- Dichaea muricata
- Dryadella edwallii
- Bulbophyllum contotisepalum
- Trichcentrum longicalcaratum
- Lockhartia oersteolii
- Chiloschista segawai
- Dendrobium dockrillia

I know it's a long list but I'll take what I get. Pictures say a thousand words

Thank you
