FIne for what?


Getting the air above winter-dry and making the orchid less

40% is below the ideal in any sense of the word.


Ideal, yes, "achievable by mere mortals who don't own a greenhouse", no.

Humidity trays don't work in my opinion either.


This is flatly untrue. One can reach %40 humidity given
humidity trays and some pebbles (which help with the surface
area that exposes the water).
