Get your Cyms big and healthy first... As you develop the culture techniques that work for you (a lot easier to make the little changes when they're confined to a pot) you will see more possibilities. Best, I think, to make small incremental modifications, see what works, then make more, rather than going "global". Project for another year...Patience...

Oh no, that was not a 'it's gonna happen', more like a maybe-in-future kind of a moment, an aftertough that left my mind. I have just one atm, and it's special (a gift from my fiance) so when i decide to experiment that much, i'm getting a new one to see where that leads.
Just that all this new information swelled my mind; gonna take a couple of days to completley unwind my mind and set some order; until then everything stays where it is.

I completley forgot, i do have one unanswered question, about the color of the leaves on the nobile. Are they one of those orchids where a bit of yellow tone just means high light and no harm?
