Good Morning - I'm up to about 80 paphs now in fairly close quarters, I've got two fans that generate solid air flow. Nonetheless, I'm noticing a few isolated instances of the little white powdery demons. I'm familiar with what happens when it gets out of control....and so now I don't grow...
I'll leave the science to those more erudite than I, but visually there has always seemed to be some daylight there, to me at least.
Great looking orchid regardless, small stature makes it a singular multi.
