Plant Humidity Control in winter for my indoor plants

I own this unit Kenmore Humidifier usually without my home is 11% which cause many of my plants to dry out 4 years ago since I bought this my home humidity has improved and my plants love it as you can see on my banana plant the leave look great and is cold and snowing outside. The bottom stone pebble trick was not working for me here in the north this Kenmore system work perfect for my plants. Stay Safe.
