Low Humidity Problem

[Lenka]

Hi guys,

hope someone can help, or rather give an advice. I seems to struggle with low humidity for my chids. Or rather in the summer as the temeruters are high outside so it's dries out the air and in the winter (october - march), when i have to have heating on. I have humidiefiers on the radiators + extra bowls with water sitting directly on top of radiators. I also placed little bowls with water in between plans ( there are all togeather) but the present humidity is still only around 39 - 41. The temerature in my flat is at the moment around 21c during the day and 16-17 in the night.
Is there some other way how to raise the humidity other then quit my job and become `Orchid Sprayer`
Thanks,
