But what do you mean by humidity, any thing that does not like arid conditions or are you looking for aquatic conditions? How much, what quantity of humidity would qualify for your conditions of humidity? We have 100% under foggy or Monsoons season but around 15% in April now under your definition of humidity which would qualify? If you are talking about muggy conditions then that should come under Tropical 80 to 100%. That to will be under rainy conditions plus heat or should I say time of year.
All the plants in the aquarium trade are not underwater plants year round. Only in the rainy season in the Amazons are they under water. Rest of the year their roots are in boggy conditions but their leaves are out of the water 100% humidity. By humidity are you looking for these plants?
