If anything I need a humidifier, since mine rarely goes above 30. If you get mold you need more ventilation, not necessarily a dehumidifier.

Like I've always said, I like to put a humidifier and a dehumidifier in a room and let them fight it out.
Also I was talking about in the context of hyrdo. If you have good ventilation in a soil garden I could see it possibly not being necessary. Again this might be a geography thing, 30% humidity in any context is unheard of around here.
