You should have explained what you
personally meant by high humidity. Here I was thinking you were absolutely crazy when I kept saying that high humidity means 50-90% and that you couldn't think of any CPs that didn't like high humidity.
100+% should be considered extremely high humidity
Yea you're right haha
A quick google search will produce that 50-90 percent is good for CP's but a tropical plant terrarium is easily over 100 percent because evaporation exceeds condensation.
Even simply putting your carnivorous plant on a shelf above or very close to an aquarium will usually prove too humid.
They can tolerate high humidity as in, 50-90%
but the need fairly dry substrate, mold and fungus is a huge killer of carnivorous plants.
But its a matter of finding the ideal plant for your situation.
I still stand by what I said earlier; a carnivorous plant in an emersed tropicals tank, be it in the soil or suspended in a planter suction cupped to the glass, probably wont make it.
Im not greatly experienced in the carnivorous plant area but I've done a lot of research.
edit: again, keep in mind your average air conditioned room is 40-60 percent humidity and CP's do just fine in this humidity with an occasional misting, I'd even venture to say this would be preferable to an environment with constant 80 percent humidity that requires no misting.
Low humidity will prevent molds provided that humans are their to intervene when conditions get too dry.
Also, there is specific humidity and relative humidity and I'm not brushed up on the difference between the two.
