Okay, there is a ton I could say here but I am going to try and keep it short as my fingers are getting tired and I have a 6 year old bugging me every 3 minutes to "go to the park"
So...
Av, check the Utric forum for my posts, I am pretty sure I still have the "How to grow Orchidioides" still in there. If not it is in the ICPS archives for sure just not sure off the top of my head which month/year.
I will caveat that I did switch my conditions up on them after the article though.
Lighting: 14/10 in summer 10/14 in winter. They like it bright too
Substrate: Really open loose media (I used 3/2/1/1 APS/live sphag/sand/peat and I tossed in some 0.5cm rock wool cube media as well, but not very much). I do not like straight sphag as a media, gets too wet in my experience
Temp: Highland conditions though some can take lowland (alpina especially)
Humidity: Moderate to high. I have grown some on windowsills at ambient humidity and they do fine. The leaves are a good indictor for the most, if they are crisping then they need more humidity.
Potting method: Those net pots you have should work just fine. They will "escape" through the holes but that is not a big deal, they actually seem to like growing that way.
I was not free to do it in my setup but if you have the ability, hang the pot. I talked with a lot of guys and was checking into this before my move and it was going to be my next step in experimentation. A number of species really seem to like the freedom afforded by growing "down" and out. Plus it keeps them from getting wet feet which they hate.
Watering: Water to keep moist but never really wet.
I disagree with this statement 100%. Too much to type now but the long and short is that this is not even close to their natural condition but is a misrepresentation of it that was published and perpetuated without research behind it. If you really think about how they grow you will understand why I disagree.
