Hello AL ! or Ray !

I have read in many books and on the monreal botanical garden that the
relative humidity for orchids like Phal, Paph, Onc should be at around 70%
during the day and 40 % at night!

Is this true? Do you do this or do you maintain the same percentage of RH
all the time?

Thanks

Claude

PS: AL, I`m very jalous of your greenhouses ! Can I go work for you! :-)
