Hi was wondering if anyone could help me regulate the humidity in my vivarium? ive done alot of research before aquiring my bp -HER NAME IS PETRA, but research can only do so much. Currently im using room temperature water and a newly purchased spray bottle to mist the tank, only thing is it will only keep it between 50 and 60 on the hygrometer for so long.....before i have to spray again and i dont want to upset her by spraying all the time.

Can anyone recommend anything/something i am doing wrong or my setup is missing something.
i have a wooden viv with climbing spot, half hot half cold, heat mat under one side with hide and heat lamp ( i alternate using the heat lamp during the day and the heat mat during the night).
Many Thanks
