Can plants cause black mold, humidity damage, etc.?

[Kuzuri]

Hey all!
I live in a single room apartment in an assisted living facility for people that for one reason or another cannot live in a regular apartment on their own, and therefore, need help to manage things like cleaning up, cooking, remembering to take their medication, and so on (I'm not a helper/part of the personnel. I'm one of the above mentioned 'people').

Anyway, I have approximately 110 plants, most of which are in my apartment/room (I say "most of which" because a couple of them are in the various common rooms). But now, the personnel claims that my plants will cause black mold and water damage to the room, because they increase the humidity that much. Is this true?

I have no humidifier or water trays to increase the humidity. I water the plants in the bathroom and also let them drain there for a few hours before putting them back in their place in my room. I make sure to open windows for as long as possible. There is never any moisture on the inside or outside of my windows, so I really doubt what they're saying is true.

But in reality, I have no idea if it is true, so I wanted to ask someone with more experience and knowledge. And that brought me here.

Hope you can help!
