Bananas do not need humidity really as long as they get enough water. I grew bananas indoors, in containers, in Colorado for 4 years, I got fruit and everything. The thing about bananas is, they really like high amount of sunlight, humidity, food, etc...but they do not need it to just be a nice houseplant. Outside in the tropics, they thrive and use up anything you give them, but they will not usually die given less than what they could use. They can be easily grown as normal houseplants, now if you want to try and produce lots of fruit, you would really have to push them, but its possible. In the winter, I just water less and they usually stop growing, or grow very slow (due to cold temperatures), but they are fine, and as soon as it warms up I start watering more and they grow faster and so it continues. I have lots of pictures in my gallery of plants I have in my house.
