Most culture sheets for Phals (or Paphs) that I have seen say something like
"humidity of 50% or higher is ideal". However, Phals are known for being
able to adapt to sub-ideal conditions (and even thrive in them), so I would
think that 40% humidity is 'good enough' (or will anyone object to that?).
One related thing that I have read is that good air movement becomes more
important with higher humidity.

Hello everyone!

What is the best percentage of humidity to grow Phal and Paph!

I just bought an hygrometer and it shows 40% of relative humidity. Is this
good?


Thanks

Claude

P.S : Happy New year, Bonne Année
