Nobody has said it solely/specifically but I thought that the humidity effects plants a bit like heat does us.

I thought the humidity specifically changed the rate of transpiration.

It also effects the amount of fungus that can viably grow.

Hope these simple pointers help,

denial102 Reviewed by denial102 on . will LOW humidity hurt a plant? If your humidity is around 20% or lower can it be bad for the plant? If it is I don't understand why it would be bad for the plant because the leaves don't absorb water do they? Rating: 5
