Today morning I noticed that one of my Phals has aerial roots with very red
tips. It must have had the very red tips before today, but I just had not
noticed. Does this mean anything? Do some Phals have red tips of aerial
roots and as long as the roots look healthy that's just the way it is? Or
does this mean anything about the level of humidity or light or anything at
all?

Just curious,
Joanna
