Have you placed a hygrometer inside the grand piano to check?
I only open the lid partially or fully if I play. Otherwise too much dust comes inside the piano. So it has to work with closed lid foremost.
However the humdifier I placed below the grand, makes his job as far as I see- the humidity inside the piano is raised with closed lid. If I open the lid, the humidity drops because the surrounding humidity is less than the humdity below the piano where the humdifier is placed.
Since the dehumidifier costs so much power (money for operating) and since my tuner told me that too dry is more dangerous as too wet, I think I will only use the humidifier.
Furthermore I do not like that artificial stuff screwed on my old Steinway.
