I used to use them when I was in a more humid region because they made me feel better. But I don't think that they are effective. Is Nebraska pretty dry? If your room is small, an ultrasonic humidifier may work well to bring the RH up to 50-60%R (fairly low cost to operate). I prefer to use a simple humidifier without build-in humidistat (which seems to be inaccurate sometimes), and maintain the humidity with Amazon.com: Zoo Med HygroTherm Humidity and Temperature Controller: Pet Supplies

If your room is big, then you need some kinds of enclosure. This is what I use:
Amazon.com: LEDwholesalers GYO1009 60-Inch x 48-Inch x 24-Inch Mylar Reflective Hydroponic Grow Tent: Patio, Lawn & Garden

But if your area isn't extremely dry (e.g. < 40%RH), the grow tent isn't probably worth it.
