This plant has bloomed twice, for some reason the petals were longer on the first flowering when I lived in a flat ~95 cm, the 2nd time only around 60cm (in the greenhouse). Should flower again in around 2 years I reckon, the new growth is just maturing.

Really nice, the pouch color is great! What are you growing it in? Any difference in RH between this bloom and previous?
 
Beautiful, is this also from Orchid Inn? Do you happen to know the cross?

It's currently growing in bark, perlite and a bit of limestone, sorry not sure what RH stands for.
 
Wow, nice! I have one of those and judging by the size of yours, I have a long wait ahead of me ...
Mine is down to a single growth. Erwina destroyed the new growth it last flowered on. The growth it stated around 10 years ago is the one that is maturing now. For some reason the leaves are much shorter on this growth.
 
RH= relative humidity
Thats what I thought. There probably wasn't much difference as in my flat I had central heating but grew under lights on gravel trays and had a 300l discus fish tank all increasing humidity, in a small room ~ 3x3 m. The greenhouse was watered every few days and had the door open. So I would expect on balance the RH was about the same. I believe the main difference was the temperature and light. the greenhouse got colder at night and when I grew under lights it was a solid 12 hrs a day.
