Tropical Mist

I have found that misting dosn't raise the humidity . But puttin wet moss in a container over the heat mat and covering most but not all of the top of the tank with plastic rap works best for me.

While Arkansas is super humid by itself, for some reason the house appears to be below average in humidity.

No, That's not what the product is made for.

As everybody suggested, a container with moisten moss and/or a daily misting with water are good ways to raise the humidity.
BUT is there even a problem yet to cure? bad shed or dry scales/skin ?
30% might suffice.

Usually during the colder months when we have central heat or a heat source running to keep a house warm it drys the air out. My humidity level in my house will get as low as 10%. I use a humidifier in my reptile room during the cold months.

Arkansas really shouldn't have a problem with humidity, especially for a corn. I keep a boa which requires slightly more humidity just fine with kansas city air, even with central heat and ac. The only time you should worry about humidity as others have stated is if shedding becomes a problem, ie. the shed is incomplete or in pieces.
